Troubleshooting

Error Messages
Check the following if an error message displays:
•
Verify ignition key is in the ON and not in the ACCES-
SORIES position.
•
Make sure the DLC 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 bro-
ken wire.
•
Check for bent or broken pins.
•
With the engine off, check for blown fuses in the
vehicle fuse box.
•
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 (dielec-
tric) grease to the mating surfaces.
•
With the key on engine off (KOEO), verify vehicle
battery voltage is at least 8.0V.
•
Verify the control module is not defective. Refer to
the service manual to diagnose the control module.
