Diagnostic Test

1.TEST FOR INTERMITTENT CONDITION

NOTE: Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.



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.

2.(Z901) GROUND CIRCUITS OPEN







Does the test light illuminate brightly for each circuit?

Yes
  • Go To 3


No
  • Repair the (Z901) ground circuits for an open.
  • Perform the ABS VERIFICATION TEST - VER 1.

3.(F202) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN OR SHORTED






Does the test light illuminate brightly?

Yes
  • Go To 4


No
  • Repair the (F202) Ignition Switch Output (Run-Start) circuit for an open or short.
  • Perform the ABS VERIFICATION TEST - VER 1.

4.(D65) CAN C BUS (+) CIRCUIT OPEN







Is resistance below 5.0 ohms?

Yes
  • Go To 5


No
  • Repair the (D65) CAN C Bus (+) circuit for an open.
  • Perform the ABS VERIFICATION TEST - VER 1.

5.(D64) CAN C BUS (-) CIRCUIT OPEN





Is resistance below 5.0 ohms?

Yes
  • Replace the Antilock Brake Module in accordance with the service information.
  • Perform the ABS VERIFICATION TEST - VER 1.


No
  • Repair the (D64) CAN C Bus (-) circuit for an open.
  • Perform the ABS VERIFICATION TEST - VER 1.
