Diagnostic Test

1.TEST FOR INTERMITTENT CONDITION


NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.



NOTE: A red X will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.


NOTE: Check the TIPM for any active CAN C hardware DTCs, perform DTC before proceeding.



Does the scan tool display a red X next to the module?

Yes
  • Go To 2


No
  • The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.

  • Perform the ABS VERIFICATION TEST - VER 1.

3.(Z907) (Z917) GROUND CIRCUITS OPEN





Does the test light illuminate brightly for each circuit?

Yes
  • Go To 4


No
