the scan tool assigns a 2 digit module ID to be used in
place of the actual CAN module ID. The module ID
assigned for the CAN module ID is used in all functions
of the scan tool.

7 Troubleshooting
7.1 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.

WARNING
Review Safety Messages on page 4
before troubleshooting.
If scan tool will not power up, communicate with vehicle
control module, pass scan tool self-tests, or functions
incorrectly in any other way, do the following:
