Safety Precautions
General Safety Guidelines to Follow When Working on Vehicles
To prevent accidents that could result in serious injury and/or damage
to your vehicle or test equipment, carefully follow these safety rules
and test procedures at all times when working on vehicles:
 Always wear a roved eye rotection.
 Always o erate the vehicle in a well-ventilated area. Do not inhale exhaust gases
 they are very oisonous!
 Always kee yourself, tools and test equi ment away from all moving or hot engine
arts.
 Always make sure the vehicle is in Park (Automatic transmission) or Neutral
(manual transmission) and that the parking brake is firmly set. Block the drive
wheels.
 Never lay tools on vehicle battery. You may short the terminals together causing
harm to yourself, the tools or the battery.
 Never use OBD II System Tester if its internal circuitry has been ex osed to any
liquids.
 Never smoke or have o en flames near vehicle. Va ors from gasoline and
charging battery are highly flammable and ex losive.
 Never leave vehicle unattended while running tests.
 Always kee a fire extinguisher suitable for gasoline/electrical/chemical fires handy.
 Always use extreme caution when working around the ignition coil, distributor ca ,
ignition wires, and s ark lugs. These com onents contain High Voltage when the
engine is running.
 When erforming a road test, Never o erate the OBD II System Tester alone while
driving the vehicle. Always have one erson drive the vehicle while an assistant
o erates the tester.
 Always turn ignition key OFF when connecting or disconnecting electrical com o-
nents, unless otherwise instructed.
 Always follow vehicle manufacturers warnings, cautions and service rocedures.
WARNING!
Some vehicles are equi ed with safety air bags. You must follow
vehicle service manual cautions when working around the air bag
com onents or wiring. If the cautions are not followed, the air bag
may o en u unex ectedly, resulting in ersonal injury. Note that the
air bag can still o en u several minutes after the ignition key is off
(or even if the vehicle battery is disconnected) because of a s ecial
energy reserve module.

Section 1: Welcome to the OBD II System Tester
1-1 Overview
OBD II (On-Board Diagnostic, second generation) systems are designed to meet or
exceed a set of standards and regulations designed to im rove air quality. The
Environmental Protection Agency (EPA), in conjunction with California Air Research
Board (CARB), issued these standards and regulations through the Clean Air Act
of1990. OBD II systems are required to monitor the erformance of emission related
systems and their com onents. The ability to detect hard and intermittent faults are
further requirements of an OBD II com liant system. The Society of Automotive
Engineers (SAE) defined several standards for OBD II systems. These standards
include criteria for the diagnostic link connector, communication, Diagnostics trouble
codes (DTCs), descri tor names, and other re air information.
This OBD II System Tester will work on OBD II com liant cars and light trucks. If you
use a vehicle service manual along with the tester, you will be able to diagnose and
re air many automotive-related roblems. Before roceeding, make sure you have
read and fully understand the material in this Manual.
1-2 The OBD II System Tester
KAL Equi s OBD II System Tester was develo ed by ex erts in the automotive
service industry to hel diagnose todays vehicles and assist in troubleshooting
rocedures. When a roblem occurs in the vehicle, its com uter will store a record of
the event and take corrective action to adjust the circuit at fault. The OBD II System
Tester will allow you to monitor these vehicle events and read DTCs from the
com uters memory to in oint roblem areas. The OBD II System Tester will
inter ret the com uter signals and rovide you with a real time readout of vehicle
data. In addition, the Code Looku feature allows you to reference code descri tions
without having to age through an instruction manual. A detailed descri tion of the
functions are rovided in Section 2: Diagnosing with the Tester.
1-3 Diagnostic Connector and Location
The OBD II System Tester communicates with
the vehicle via a diagnostic link connector (DLC).
OBD II S ecification J1962 defines the DLCs
hysical and electrical ro erties. The DLC is
known as the J1962 connector. The S ecification
J1962 was introduced by the SAE (Society of
Automotive Engineers) to make all com liant
vehicles use the same DLC with the generic link
information available on the same ins, no
matter what make of vehicle. In addition to the
connector s ecification, there is a guideline on
where to locate the DLC or J1962 connector, which
states it should be located under the dashboard on the
drivers side of the vehicle. Even with this guideline, not
all OBD II DLCs are located under the dash on the
drivers side. If the DLC is not located in the s ecified area, then a note will be laced
where the DLC should be informing the user of the location. If you cannot find the
DLC, see the vehicle service documentation for its location.

easy viewing. This hel s make the OBD II System Tester more user friendly by
offering a large viewing area to dis lay most Hel and Instructional messages. This
uts more information on the dis lay to reduce reference to rinted materials. The
dis lay will su ort a number of hel ful symbols that will rom t you through test
routines. These symbols are shown and defined below:
|Question Mark in lower right corner means there is help available for this screen
or current selectable item.
`Pointer (cursor) is used to indicate current selectable choice.
[Down Arrow indicates there is additional
information on the next screen.
]U Arrow indicates there is additional
information on previous screen.
LISTS, MENUS AND QUESTIONS
The OBD II System Tester is designed to be as intuitive as ossible. That is, its
functions and controls should be easy to understand and use the first time you try it.
All menu and screen lists o erate the same way. By using the UP and DOWN arrow
keys, you can move the cursor to a selection of your choice. The ENTER key selects
that function or item. The screen exam le above illustrates a few selections available
on the OBD II Function Menu.
Notice, in the screen below on the left, how the cursor (`) is ointing at 1)Read
Codes. If you wish to read the vehicles DTCs, ress the ENTER key to select that
function. To make a different choice, such as View Data, use the DOWN arrow key to
move the cursor down to ) View Data and ress the ENTER key to select the View
Data function.
Sometimes, a list will be longer than three or four items, and will not fit on a single
screen. In these cases, the down arrow symbol ([) is visible in the last column of the
dis lay, indicating that there are more choices on the next screen, as shown below
on the left. To go to the next choice, use the DOWN arrow key to move the cursor
down the list. Kee going even after you have reached the bottom of the screen. The
dis lay will scroll to the list, shown above on the right:
You should see that there are now arrows in the last column ointing u and ointing
down. This indicates that you can use the UP arrow key to move the cursor to the
revious screen or the DOWN arrow key to move the cursor to the next screen.
Once the bottom of the list is reached, you will notice that there is now only an UP
arrow (]) in the last column. This indicates that you have reached the end of this list,
and that all other choices are on revious screens. You can return to those screens
by ressing the UP arrow key. These u and down arrow characters on the screen
are used throughout the OBD II System Tester. The UP and Down arrow keys work
exactly the same way, even if you are just scrolling through text such as the On-Line
Hel screen.

that articular screen or item. To enter On-Line
Help, ress the ? key. The O erating Error
hel screen is shown at the right.
The text in On-Line Help screens are in
CAPITAL letters to remind you that you are
viewing On-Line Help screens and not screens associated with a function. Some On-
Line Hel messages are longer than one screen. If this is the case, the arrow
symbols (][) will a ear in the last column of the dis lay. A [ means more
information available on the next screen and a ] means more information available
on the revious screen. Use the UP and DOWN arrow keys to age u or down
through a series of On-Line Hel screens.
The On-Line Hel screen shown above has a [in the last column. To view the next
On-Line Hel screen, ress the DOWN arrow key.
Notice now that both arrow symbols (][) are
visible in the last column of the dis lay. This
indicates that you can either age u to a
revious On-Line Hel screen, or age down to
the next On-Line Hel screen by using the UP
and DOWN arrow keys. The revious On-Line Hel screen is always the one you just
viewed, just as with Function Menu.

Section 2: Diagnosing with the Tester
2-1 Preliminary Checks
Before using the OBD II System Tester on your vehicle, it is a good idea to erform a
com lete visual ins ection. You can find the cause of many driveability roblems by
just looking, thereby saving yourself a lot of time. Check the following items before
roceeding with OBD II System Tester testing:
oHas the vehicle been serviced recently? Sometimes things get reconnected in
the wrong lace, or not at all.
oDont take shortcuts. Ins ect hoses and wiring which may be difficult to see
because of location beneath air cleaner housings, alternators and similar
com onents.
oIns ect the air cleaner and ductwork for defects.
oCheck sensors and actuators for damage.
oIns ect all vacuum hoses for:
 Correct routing. Refer to vehicle service manual, or Vehicle Emission Control
Information (VECI) decal located in the engine com artment.
 Pinches and kinks.
 S lits, cuts or breaks.
oIns ect wiring for:
 Contact with shar edges (this ha ens frequently).
 Contact with hot surfaces, such as exhaust manifolds.
 Pinched, burned or chafed insulation.
 Pro er routing and connections.
oCheck electrical connectors for:
 Corrosion on ins.
 Bent or damaged ins.
 Contacts not ro erly seated in housing.
 Bad wire crim s to terminals.
NOTE: Problems with connectors are common in the engine control system. Ins ect
them carefully for corrosion, bent ins, ushed out ins, or over ex anded
ins. Some connectors use a s ecial grease on the contacts to revent
corrosion. Do not wi e off! Obtain extra grease, if needed, from your vehicle
dealer. It is a s ecial ty e for this ur ose.
2-2 OBD II Functions
During the functions described below, a communication link is established, allowing
the OBD II System Tester and the vehicles PCM to exchange information. The way in
which this information is exchanged is referred to as a data stream or data links. The
OBD II Function Menu shows all OBD II Generic functions. Not every vehicle will have
every function that is listed. If the function or art of function selected is not su orted
by the vehicle, a message screen informing you of this will be dis layed.

9
After you select OBDII Functions from the MAIN MENU the OBD II System Tester will
automatically link to the PCM and check the OBD II Readiness Monitors. OBD II
Readiness Monitors are strategies designed to test the o eration of emission related
systems or com onents. The PCM may erform s ecial tests on a system or
com onent to com lete its monitor. The vehicle may have to be o erated under
certain conditions to initiate a monitor. If the PCM loses ower or the codes are
erased the monitors will be cleared. The OBD II System Tester will dis lay the
condition of vehicles OBD II Monitors.
Below is an exam le of the screen when the OBD II readiness monitors are com-
leted. If any of the monitors are not com leted, the following screen on the right will
be dis layed.
Press the down arrow key to view a list of the monitors. The monitor list consists of
the OBD II monitor name followed by the monitors condition. A monitor that is not
su orted by the test vehicle will be followed
by n/a, (not a licable). A monitor that has
been com leted will be followed by OK. If a
monitor has not been com leted, it will be
follower by inc for incom lete.
Press the BACK key and the OBD II Function Menu will dis lay. Use the UP and
DOWN arrow keys to scroll through the choices.
IMPORTANT: If you choose a test that your vehicle does not su ort, you will get a
message telling you that the test is not a licable.
Read Codes
The Read Codes function is used to retrieve Diagnostic Trouble Codes (DTCs) from
the vehicles on-board com uter. Diagnostic Trouble Codes are set when the PCM
recognizes a condition outside reset ranges. A Malfunction Indicator Lam (MIL) that
is on indicates that a DTC has been recorded. Because DTCs indicate a circuit or
system failure not com onent failures they are very useful in diagnosing vehicle
concerns.
NOTE: Changing arts without diagnosing the circuit or system may result in good
com onents being unnecessarily re laced.
Select Read Codes from the OBD II Function
Menu and ress the ENTER key. The PCM will
check its memory and re ort trouble condi-
tions that were stored.
NOTE: If you get an O erating Error message, make sure the DLC ada ter cable is
ro erly attached to the vehicle connector. If the roblem remains, refer to
Section : On-Line Help and Trouble-Shooting Tips.

When the tester has finished reading the DTCs, one of two ossible screens is
dis layed. If there are no DTCs stored in the vehicles on-board com uter, a
System Pass screen is dis layed. If there are DTCs stored in the vehicles on-
board com uter, then the OBD II System Tester dis lays the number of codes found.
If codes are retrieved, ress the DOWN arrow to view the DTC(s). Definitions for
Generic DTCs (SAE J2012) will be dis layed. Manufacturer s ecific DTCs will just
dis lay the code, no definition. Use an a ro riate service manual to obtain code
definitions. When more than one DTC is received, the DOWN arrow will be dis layed
on the right of the screen. The arrow indicates additional code information is avail-
able. Use the DOWN arrow key to view the codes stored in memory. The last code
screen will just have a ]symbol in the last column of the dis lay. This indicates that
this is the last screen and additional code information is found on revious screens.
Use the BACK key to return to the OBD II Function Menu.
Pending Codes (or Continuous Test Codes)
The ur ose of this function is to obtain test results for continuously monitored
emission-related owertrain com onents and systems. Certain tests are run
continuously as the vehicle is driven within ro er o erating conditions. Unlike some
trouble codes this function re orts the test results after a single drive cycle. The
Pending Codes function is identical to the Continuous Test function and is useful
after a vehicle re air or after clearing the PCMs diagnostic information. Test results
re orted by this function do not necessarily indicate a faulty com onent or system.
To view the test results, select Pending Codes or Continuous Test from the OBDII
Function Menu and ress the ENTER key.
If no Pending Codes exist, the OBD II System
Tester will dis lay a single message screen
indicating this condition.

NOTE: If you get an O erating Error message, make sure the DLC ada ter cable is
securely attached, and the ignition key is ON, then try again. If the roblem
remains, refer to Section : On-Line Help and Trouble-Shooting Tips.
If any of these tests indicate a fault, the DTCs
will be dis layed in the same format as Read
Codes. The tester will dis lay codes similar to
trouble codes. Press the DOWN arrow to view
the ending code(s).
A DOWN arrow dis layed on the right of the screen indicates additional codes can
be found on the next screens. Use the DOWN arrow key to view the codes stored in

a]symbol in the last column of the dis lay.
This indicates no more codes are available.
Use the UP arrow key to view the revious
codes.
Use the BACK key to return to the OBD II Function Menu.
Erase Codes
The Erase Codes function is used to erase the trouble codes from the test vehicles
PCM. This function also erases freeze frame data, O2 sensor test data, and on-board
monitoring test results, and resets the system monitors to the Not Ready status.
Because of this you should erase codes only after you have checked the systems
com letely. Erase Codes should be erformed at Key On, Engine Off to ro erly clear
the PCM.
To Erase Codes from your vehicles on-board
com uter, select Erase Codes from the OBDII
Function Menu.
A confirmation screen will be dis layed to verify
that you wish to erase codes. Select YES to
erase the diagnostic results from the PCM or
NO to cancel and retain the data.
If YES is selected, ress the ENTER key and a
message to Turn ignition key ON, engine
OFF will dis lay. Press the ENTER to con-
tinue. A Command Sent message is mo-
mentarily dis layed before returning to the
OBD II Function Menu.
NOTE: If you choose No, a Command Cancelled message a ears. Hard codes,
are trouble codes that will remain in the vehicles PCM memory until the
condition is re aired.
NOTE: If you get an O erating Error message, make sure the DLC ada ter cable is
securely attached, and the ignition key is ON, then try again. If the roblem
remains, refer to Section : On-Line Help and Trouble-Shooting Tips.

View Data
This function is used to view vehicle Parameter Identification Data (PID) in real time.
A art from Read Codes, View Data is the most hel ful diagnostic function for deter-
mining the cause of a driveability roblem. View Data is most often used for observ-
ing sensor data and the ON/OFF states of switches, solenoids and relays.
NOTE: Multiple Responses to a PID Request - Vehicles equi ed with more than
one on-board com uter, for exam le a PCM and TCM (Transmission Control
Module), can res ond with multi le results to a certain arameter identifi-
cation data (PID). In View Data, the OBD II Tester identifies the modules with
their manufacturer assigned names such as $10 or $1F by blinking the
module name near the end of the PID name. A PID that receives multi le
res onses, such as Engine (RPM), will dis lay on two lines.
To view your vehicles PIDs, select View Data
from the OBD II Function Menu and ress the
ENTER key.
The OBD II System Tester will dis lay the
generic OBD II PIDs su orted for the vehicle
under test. Not all vehicles will have the same
PIDs. Do not worry this is normal. The PIDs
covered by the OBD II System Tester are
defined in Appendix B.
Press the BACK key to dis lay the OBD II Function Menu.
NOTE: If you get an O erating Error message, make sure the DLC ada ter cable is
securely attached and the ignition key is ON, then try again. If the roblem
remains, refer to Section : On-Line Help and Trouble-Shooting Tips.
View Freeze Data
When an emission related fault is detected by the PCM the engine conditions are
recorded and stored in memory. This recording is known as a freeze frame. The
freeze frame is like a sna shot of the engine o erating conditions at the time of a
fault. Freeze frame data can only be overwritten by another fault with higher riority.
The OBD II System Tester will allow you to look at the freeze frame data stored in the
PCMs memory.
NOTE: If the Erase Codes function was erformed, then no freeze frame data will
be stored in the vehicles memory.
To view the freeze frame data, select View
Freeze Data from the OBD II Function Menu.

13
After selecting View Freeze Data, the OBD II
System Tester establishes a communication
link to the vehicles PCM. All PIDs su orted by
the vehicle are dis layed. Use the UP and

Record Data
The Record Data function is used to record vehicle Parameter Identification Data (PIDs)
while the vehicle is arked or being driven. This function is mainly used for diagnosing
intermittent driveability roblems that cannot be diagnosed by any other method. For
exam le, if your vehicle sometimes loses ower while going u stee hills, then you
should start a recording as soon as your vehicle reaches the base of the hill. The OBD II
System Tester records the su orted PIDs in Frames at various time intervals. The first
5 Frames are recorded rior to the start time (0.0 seconds) Once started, Frames will
be recorded for 8 to 35 seconds; the number of Frames de ends on the vehicles data
rate and quantity of PIDs. The Record Data function allows you to diagnose an intermit-
tent roblem by analyzing data leading u to the roblem, during the roblem, and
ossibly after the roblem, de ending on roblem duration. The PIDs covered by the
OBD II System Tester are defined in Appendix B.
Select Record Data from the OBD II Function Menu and ress the ENTER key. The
Pick Trigger Method menu is dis layed next. Select either Manual Trigger or Trigger
on Codes then ress the ENTER key.
If the memory is full from a revious recording,
it must be erased before recording more data.
To erase memory and continue, select YES
and ress the ENTER key and then the Pick
Trigger Method o tions will dis lay. Otherwise,
select NO and ress the ENTER key to return
to the OBD II Function Menu.
NOTE: If you get an O erating Error message, make sure the DLC cable is securely
attached, and the ignition key is ON, then try again. If the roblem ersists,
refer to Section of this Manual: On-Line Help and Trouble-Shooting Tips.

The OBD II System Tester initializes by
establishing the time intervals and then
recording the first five Frames of data. When
done, the system tester is ready to record data.
To cancel this function, ress the BACK key to
return to the OBD II Function Menu.
If Manual Trigger was selected, then the OBD
II System Tester will start recording when the
ENTER key is ressed.
If Trigger on Codes was selected, then the
tester will automatically start recording when a
trouble code is set in the vehicles on-board
com uter. Press the BACK key to cancel and
return to the OBD II Function Menu.
WARNING! Never operate the OBD II System Tester and drive your vehicle at
the same time. Always have one person drive the vehicle while a
helper operates the tester.
The tester records for a time of varying duration. Remember, your recording will
consist of 5 Frames of data rior to the start of the recording, and a number of
Frames after with time intervals of 5 seconds or longer (de ending on the number of
PIDs). All a licable data arameters will be recorded for your vehicle.
When the recording is in rogress, screens
like the exam le below are dis layed for the
duration of the recording, dis laying the Frame
Number being recorded. You can record all the
frames or ress the ENTER key any time to
sto recording.
Next, You will be asked if you want to lay back
the recording now. If you answer YES, then
the Playback Data function will dis lay,
Answering NO returns you to the OBD II
Function Menu.
Playback Data
The Playback Data function is used to layback a recording. This function is very
similar to View Data. The only difference is that View Data is a real time viewing of
vehicles PIDs, while Playback Data is a viewing of reviously recorded ones.
To view the PIDs recorded in the Record Data
function, select Playback Data from the OBD II

No Recording Present, Please Make Record-
ing First will dis lay. The Record Data function
must be erformed in order to lay back the
data. Press the BACK key to return to the OBD II OBD II Function Menu and select
Record Data to make a recording.
If recorded data exists, the PIDs, Frame
number and Time are dis layed.
NOTE: Multi le-res onse PIDs (see View Data) are dis layed with their module
address in one frame and their measurement values in the next frame. Use
the LEFT/RIGHT arrow key to alternate between the frames to identify the PIDs
and their measurement values.
On the Playback Data screen, lines 1-3 are used to dis lay the vehicles PIDs. Use
the UP/DOWN arrow keys to scroll through the PID list. The end of the list is reached
when only the UP arrow is dis layed at the right of line 3. The PID list scrolls line-by-
line and will not wra around to the beginning.
Use the LEFT/RIGHT arrow key to move through the Frame/Time index. Frame 0/
Time 0.0 is the trigger oint; where the recording was started by either Manually
Triggering or by Triggering On Codes. Frames -5 to -1 contain data rior to the trigger
oint.
NOTE: After reaching the last Frame/Time interval, the system tester will wra  to
the first Frame/Time interval recorded. The Frame/Time dis lay will change
from a ositive to the first negative number viewed. This is normal. The LEFT/
RIGHT arrow may be used to scroll through all time intervals.
A Frame is a sna shot of engine o erating conditions at a certain time. The
relationshi between the Frame index and the Time index are based on the vehicles
on-board com uter data rate and the number of PIDs being read. Remember, not all
OBD II vehicles use the same data stream (communication rotocol), data rates
(baud) and the same number of PIDs. For this reason, not all vehicles will start and
end with the same Frame number. The Frame number increases every time data is
transmitted from the vehicle to the OBD II System Tester. The intervals when this
occurs increases for slower data rates and larger PID lists. Frame 0 occurs at the
trigger oint, Time 0.0. Thus, negative and ositive Frame numbers contain data
before and after the trigger oint, res ectively.
NOTE: Some vehicles will wait 3 to 4 minutes after the driveability roblem first occurs
before storing a trouble code in the vehicles on-board com uter. If you
selected Trigger On Codes when you made your recording, you might not
see any drastic change in data arameters before and after the trigger oint.
In cases like this, it is better to manually trigger the start of the recording when
the driveability sym tom is first observed.
When you have finished laying back a recording, ress the BACK key to return to
the OBD II Function Menu.

O2 Monitor Test
NOTE: This is NOT an on-demand test. The O2 sensors are not tested when this
menu selection is made. The O2 sensors were tested at an earlier time when
engine o erating conditions were correct.
OBD II regulations require the vehicle to monitor and test the oxygen sensors. The O2
Monitor Test selection allows the technician to retrieve the com leted test information
on the oxygen sensors from the PCM. Information on the oxygen sensor monitors will
be hel ful in recognizing sensor or system roblems related to fuel and emissions. The
oxygen sensor test may include the following information:
To view the oxygen sensor test results, select
O2 Monitor Test from the OBD II Function
Menu and ress the ENTER key.
Once the O2 Monitor Test has been selected
the recommended oxygen sensor tests list will
be dis layed. Select which test you want to
review using the UP/DOWN arrow keys then
ress the ENTER key.
The OBD II System Tester will dis lay selected
information for all the vehicles oxygen sen-
sors. Listing the sensors together makes their
data easier to com are. Tests not su orted
by the test vehicle will return three dashes after
the sensor name.
NOTE: If you get an O erating Error message, make sure the DLC ada ter cable is
securely attached and the ignition key is ON, then try again. If the roblem
remains, refer to Section : On-Line Help and Trouble-Shooting Tips.
NOTE: Remember that some sensors are before the catalytic converter ( recatalyst)
and some are after ( ostcatalyst). The recatalyst and ostcatalyst O2
sensors may act differently. Use the arrow keys to scroll through list if
necessary.

Non-Continuous Tests
The ur ose of this function is to obtain test results for emission-related owertrain
com onents and systems that are not continuously tested. Certain tests are run only
once er drive cycle when the vehicle is within ro er o erating conditions. This
function re orts the test results after a single drive cycle. The Non-Continuous Test
function is useful after a vehicle re air or after clearing the PCMs diagnostic informa-
tion. Test results re orted by this function do not necessarily indicate a faulty com o-
nent or system. Exam les of systems not continuously monitored are catalyst and
eva orative OBD II monitors.
To view the Non-Continuous Monitors test
results, select Non-Contin Test from the OBD II
Function Menu and ress the ENTER key.
The OBD II System Tester will request the vehicle to transmit the test IDs for available
non-continuous tests and dis lay them in a list. The vehicle manufacturer is res on-
sible to assign test IDs and com onent IDs to distinguish between the different
systems and com onents. Refer to vehicle service manuals for test IDs and definitions.
NOTE: If you get an O erating Error message, make sure the DLC ada ter cable is
securely attached, and the ignition key is ON, then try again. If the roblem
remains, refer to Section : On-Line Help and Trouble-Shooting Tips.
Select a test ($xx) from the list then ress the
ENTER key. Selected test results are re-
quested by the OBD II System Tester may also
include test limits. Only one test limit is usually
included in a res onses message and
dis layed on the screen. The single limit could be either minimum or a maximum
test limit. The OBD II System Tester will dis lay the test ID, system or com onent ID
the test measurement, s ecification and status.
The first line of the dis lay will show the Non-
Continuous test that was selected using its ID
number. The ID column dis lays the system or
com onent ID number, refer to vehicle service
manual for ID definitions and ex lanations. A
column labeled MEAS will contain the measured data of the test. The test measure-
ment data is dis layed in hexadecimal number format (a system based on 16 digits
where letters A through F re resent the digits greater than 9. The s ecification
values for the system tested are found in SPEC column and dis layed in hexadeci-
mal number format. The final column, STS (Status) information is calculated by the
OBD II System Tester using the measurement and s ecification data. The status can
be Low, High or OK, de ending u on the measurements relationshi to the s ecifi-
cation.

I/M Readiness
The ur ose of the I/M (Ins ection and Maintenance) Readiness function is to dis lay
the current status of emissions-related systems required by OBD II regulations. The
o eration of emission-related systems and com onents are verified using monitors. .
The scan tool will dis lay the condition of vehicles OBD II Monitors. Monitors are
used by the vehicles PCM to check the ro er o eration of systems and com onents
as well as identifying out-of-range values. The PCM may erform a s ecial test on a
system or com onent to com lete its monitor. A vehicle may have to be o erated
under certain conditions for the monitor test to be erformed. If the vehicles PCM
loses ower or the Erase Codes function has been erformed, then the status of the
monitors will be reset.
To view the status of su orted monitors,
select I/M Readiness from the OBD II Function
Menu and ress the ENTER key.
