2. Ignition Key is not turned ON.
3. The vehicle is not OBDII compliant.
Note:
To check whether the vehicle being tested is OBDII compliant, always
refer to the Vehicle Emission Control Information (VECI) decal located
under the
hood or by the radiator of most vehicles. See below).
2.1.1 – READ DTCs
✓ Selecting this function allows the Scan Tool to read the DTCs
from the vehicle’s control modules. DTCs are used to help
determine the
cause of a problem or problems within a vehicle. These codes cause the
control module to illuminate the malfunction indicator lamp
(MIL) when emission-related or drivability fault occurs. MIL
is also known as service engine soon or check engine lamp.
✓ READ DTCs can be done with the Key On Engine Off (KOEO)
or with the Key On Engine Running (KOER).

2.1.2 - ERASE DTCs
Selecting this function erases the DTCs from vehicle’s control module(s)
memory. Perform this function with KOEO. Do not start the engine.

✓ The ERASE DTCs function resets all the I/M Readiness Monitor Status
to a not RUN “flashing” condition. To set all of the Monitors to a DONE
status, an OBDII Drive Cycle must be performed. Please refer to the

2.1.4 - FREEZE FRAME
- 11 -
When an emission-related fault has occurs, certain vehicle conditions are recorded
by the on-board computer. This information is referred to as Freeze Frame data.
FREEZE FRAME is a snapshot of the operating conditions at the time of an
emission-related fault had occurred.
✓
FREEZE FRAME can be overwritten by faults with a higher priority.
✓ If DTCs were erased, FREEZE FRAME may not be stored in vehicle
memory depending on vehicle.

2.1.5 - MIL STATUS
When the vehicle on board computer detects a problem in the emission related
systems or components, its diagnostic program will assign a fault code (DTC) and
store it in its memory. It also records a “Freeze Frame” of the conditions present
when the fault was found and set the Malfunction Indicator Lamp (MIL) alight. Some
faults require detection for two trips in a row before the MIL is turned on.
Three typical examples of MIL are shown below:

Definition of Trip
‘A Trip’ is define as a Key-ON, Key-OFF event in which the power-train control
module (PCM) detects the following:
o
• Engine coolant temperature should exceed 70 C
o
• Engine coolant temperature should change more than 20 C after starting the
engine.
• Engine speed should go over 400 RPM.
st
When the power-train control module (PCM) detects a fault during the 1 trip, the
DTC and the corresponding ‘Freeze Frame’ data are stored in the PCM’s memory.
nd
The MIL will not light up until the fault is again detected during the 2 trip. Certain
DTCs are capable of turning the Malfunction Indicator Light (MIL) ‘ON’ or ‘blinking’
during the first trip.
To access to this function, go to ‘New Scan’ Menu and
select MIL Status icon:

If there is no fault in the system, then
the screen will display as shown:
2.1.6 - I/M Readiness
The I/M Readiness (Inspection / Maintenance Readiness) function is used to
view a snapshot of the operations on the emission system on OBD II vehicles.
✓ I/M Readiness is a very useful function. To guarantee no faults exist and to
make sure all monitors are okay or not present and no DTCs exist.
- 13 - ✓ Always refer to the vehicles service manual for the Drive Cycle operation.
✓ During normal driving conditions, the vehicle’s computer scans the
Emission system. After a specific amount of drive time (each monitor
has specific driving conditions and time required), the computer’s

monitors decide if the vehicles emission system is working correctly
or not as well as detecting out of range values. When the monitor’s
status is:
• Has Run - vehicle was driven enough to complete the monitor.
• Has Not Run - vehicle was not driven enough to complete the
monitor.
• Don’t support- vehicle does not support that monitor.
✓ Depending on the vehicle, disconnecting or a discharged battery may
erase DTCs and clear monitor status.
✓ Monitors may be cleared by:
❒ Erasing DTCs
❒ Vehicle control modules losing power
✓ I/M Readiness Monitor Status can be done with the KOER or KOEO.

2.1.7 – Vehicle Information (VIN
)
This Vehicle Information (VIN) function allows the Scan Tool to request the
vehicle’s VIN number, calibration ID(s) which identifies software version in
vehicle control module(s), and calibration verification numbers (CVN(s).)
- 15 - ✓ Vehicle Information (VIN) function applies to model year 2000 and newer
OBD II compliant vehicles.
✓ The Scan Tool cannot verify if data is correct for scanned vehicles.

✓ CVNs are calculated values required by OBD II regulations.
✓ The CVN calculation may take several minutes.
✓ CVNs are reported to determine if emission-related calibrations have been
changed. Multiple CVNs may be reported for a control module.

2.3.0 - Select M.F (Manufacturer)
Vehicle Manufacturer specific codes are non-uniform DTCs. Areas within each alpha
designator have been made available for manufacturer-controlled DTCs such as
P1xxx, P30xx, U1xxx, etc. These are fault codes (DTCs) that will not generally be
used by a majority of the manufacturers due to basic system differences,
implementation differences, or diagnostic strategy differences.
Each vehicle manufacturer or supplier who designs and specifies diagnostic
algorithms, software, and diagnostic trouble codes are strongly encouraged to remain
consistent across their product line when assigning codes in the manufacturer
controlled area.
For powertrain codes, the same groupings should be used as in the ISO /SAE
controlled area, i.e. 100's and 200's for fuel and air metering, 300's for ignition system
or misfire, etc.
Code groupings for non-powertrain codes will be specified at a later date.
While each manufacturer has the ability to define the controlled DTCs to meet their
specific controller algorithms, all DTC words shall meet ISO 15031-2.
Note:
Correct selection of the Manufacturer on which the vehicle being tested will provide
more information in the HELP mode.
