Safety Precautions
SAFETY FIRST!

SAFETY FIRST!
This manual describes common test procedures used by experienced
service technicians. Many test procedures require precautions to avoid
accidents that can result in personal injury, and/or damage to your
vehicle or test equipment. Always read your vehicle's service manual
and follow its safety precautions before and during any test or service
procedure. ALWAYS observe the following general safety precautions:
When an engine is running, it produces carbon monoxide,
a toxic and poisonous gas. To prevent serious injury or
death from carbon monoxide poisoning, operate the vehicle
ONLY in a well-ventilated area.
To protect your eyes from propelled objects as well as hot
or caustic liquids, always wear approved safety eye
protection.
When an engine is running, many parts (such as the
coolant fan, pulleys, fan belt etc.) turn at high speed. To
avoid serious injury, always be aware of moving parts.
Keep a safe distance from these parts as well as other
potentially moving objects.
Engine parts become very hot when the engine is running.
To prevent severe burns, avoid contact with hot engine parts.
Before starting an engine for testing or troubleshooting,
make sure the parking brake is engaged. Put the
transmission in park (for automatic transmission) or
neutral (for manual transmission). Block the drive wheels
with suitable blocks.
Connecting or disconnecting test equipment when the
ignition is ON can damage test equipment and the vehicle's
electronic components. Turn the ignition OFF before
connecting the Scan Tool to or disconnecting the Scan
Tool from the vehicle’s Data Link Connector (DLC).
To prevent damage to the on-board computer when taking
vehicle electrical measurements, always use a digital
multimeter with at least 10 megOhms of impedance.
Fuel and battery vapors are highly flammable. To prevent
an explosion, keep all sparks, heated items and open
flames away from the battery and fuel / fuel vapors. DO
NOT SMOKE NEAR THE VEHICLE DURING TESTING.
Don't wear loose clothing or jewelry when working on an
engine. Loose clothing can become caught in the fan,
pulleys, belts, etc. Jewelry is highly conductive, and can
cause a severe burn if it makes contact between a power
source and ground.

number. Each fault is assigned a code number that is specific to that
fault. The DTC number is color-coded as follows:
RED - Indicates the currently displayed DTC is a STORED OR
PERMANENT DTC.
YELLOW - Indicates the currently displayed DTC is a PENDING
DTC.
GREEN - In cases where no codes are retrieved, a “No DTCs
are presently stored in the vehicle’s computer” message is
shown in green.
7. Code Number Sequence - The Scan Tool assigns a sequence
number to each DTC that is present in the computer’s memory,
starting with “1.” This number indicates which code is currently
displayed. Code number “1” is always the highest priority code, and
the one for which “Freeze Frame” data has been stored.

Retrieving and using Diagnostic Trouble Codes (DTCs) for
troubleshooting vehicle operation is only one part of an
overall diagnostic strategy.
CODE RETRIEVAL PROCEDURE
Never replace a part based only on the DTC definition.
Each DTC has a set of testing procedures, instructions and
flow charts that must be followed to confirm the location of
the problem. Always refer to the vehicle's service manual
for detailed testing instructions.
Check your vehicle thoroughly before performing
any test.
ALWAYS observe safety precau-
tions whenever working on a
vehicle.
1. Turn the ignition off.
2. Locate the vehicle's 16-pin Data Link
Connector (DLC).
Some DLCs have a plastic cover
that must be removed before
connecting the Scan Tool cable
connector.
If the Scan Tool is ON, turn it OFF
BEFORE connecting the Scan
Tool to the DLC.
3. Connect the Scan Tool to the vehicle’s DLC. The cable connector is
keyed and will only fit one way.
If you have problems connecting the cable connector to the DLC,
rotate the connector 180°.
If you still have problems, check the DLC on the vehicle and on
the Scan Tool.
4. Turn the ignition on. DO NOT start the engine.
5. When the Scan Tool is properly connected to the vehicle’s DLC, the
unit automatically turns ON.
If the unit does not power on automatically, it may indicate there
is no power present at the vehicle’s DLC connector. Check the
fuse panel and replace any burned-out fuses.
If replacing the fuse(s) does not correct the problem, consult
your vehicle’s repair manual to identify the proper computer
(PCM) fuse/circuit, and perform any necessary repairs before
proceeding.

6. The Scan Tool automatically starts a check of the vehicle’s
computer to determine which type of communication protocol it is
using. When the Scan Tool identifies the computer’s communication
protocol, a communication link is established.
A PROTOCOL is a set of rules and procedures for regulating
data transmission between computers, and between testing
equipment and computers. As of this writing, five different
types of protocols (ISO 9141, Keyword 2000, J1850 PWM,
J1850 VPW and CAN) are in use by vehicle manufacturers.
If the Scan Tool fails to link to the vehicle’s computer, a
“Communication Error” message shows.
- Ensure your vehicle is OBD2 compliant.
- Verify the connection at the DLC, and verify the ignition is ON.
- Turn the ignition OFF, wait 5 seconds, then back ON to reset
the computer.
- Press POWER/LINK to continue.
If the Scan Tool cannot link to the vehicle’s computer after three
attempts, the message “Contact Technical Support” displays.
- Press the SYSTEM MENU button to return to the System
Menu.
- Turn the ignition off, and
disconnect the Scan Tool.
- Contact Technical Support for
assistance.
7. If the Scan Tool can decode the Vehicle
Identification Number (VIN) for the
vehicle under test, the Confirm Vehicle
screen displays.
If the information shown is correct for the vehicle under test,
select Yes, then press ENTER . Proceed to step 10.
If the information shown is not correct for the vehicle under test,
or if you wish to manually select the vehicle, select No, then
press ENTER . Proceed to step 8.
If the Scan Tool cannot decode the Vehicle Identification
Number (VIN) for the vehicle under test, the Select Vehicle
screen displays. Proceed to step 8.
8. When No is selected from the Vehicle
information screen, the Select Vehicle
screen displays. The Select Vehicle
screen lists the three most recently
tested vehicles.
