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 DTC's, 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.(F202) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN OR SHORTED








Does the test light illuminate brightly?

Yes
  • Go To 3


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

3.(A923) FUSED B(+) CIRCUIT OPEN OR SHORTED





Does the test light illuminate brightly?

Yes
  • Go To 4


No
  • Repair the (A923) Fused B+ circuit for an open or short.
  • Perform the appropriate VERIFICATION TEST.

4.(Z967) GROUND CIRCUIT OPEN






Does the test light illuminate brightly?

Yes
  • Go To 5


No
  • Repair the (Z967) ground circuit for an open.
  • Perform the appropriate VERIFICATION TEST.

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






Is the resistance below 5.0 ohms?

Yes
  • Go To 6


No
  • Repair the (D65) CAN C Bus (+) circuit for an open.
  • Perform the appropriate VERIFICATION TEST.

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





Is the resistance below 5.0 ohms?

Yes
  • Replace and program the All Wheel Drive Control (AWD) Module in accordance with the service information.
  • Perform the appropriate VERIFICATION TEST.


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