Error Messages
Check the following if an error message displays:
❒
Verify ignition key is in the ON and not in the ACCESSORIES
position.
❒
Make sure OBD II Cable is attached to vehicle’s data link
connector (DLC) and Scan Tool.
❒
Look at DLC and check for cracked or recessed pins, or for any
substance that could prevent a good electrical connection.
❒
Test for continuity between the DLC wiring and the computer. In
an extreme case, there may be a broken wire.
❒
Check for bent or broken pins.
❒
With the key on engine off (KOEO), check for blown fuses.
❒
Make sure the vehicle’s control module has a good ground. If the
computer case is grounded, then clean the connection and apply
a conductive (dielectric) grease to the mating surfaces.
❒
With the KOEO, verify battery voltage is at least 8.0V
❒
Verify the control module is not defective. Refer to the service
manual to diagnose the control module.
