No Response From All Wheel Drive Control Module (AWD)

NO RESPONSE FROM ALL WHEEL DRIVE CONTROL (AWD) MODULE





For a complete wiring diagram, refer to the wiring information .






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.

1. Turn the ignition on.

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

2. With the scan tool, select ECU View.

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




1. Turn the ignition off.
2. Disconnect the AWD harness connector.
3. Turn the ignition on.
4. Using a 12-volt test light connected to ground, check the (F202) Ignition Switch Output (Run-Start) circuit.

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 AWD VERIFICATION TEST. . .

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




1. Using a 12-volt test light connected to ground, check the (A923) Fused B+ circuit.

Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the (A923) Fused B+ circuit for an open or short.
- Perform the AWD VERIFICATION TEST. .

4. (Z967) GROUND CIRCUIT OPEN




1. Turn the ignition off.
2. Using a 12-volt test light connected to 12-volts, check the (Z967) ground circuit.

Does the test light illuminate brightly?

Yes

- Go To 5

No

- Repair the (Z967) ground circuit for an open.
- Perform the AWD VERIFICATION TEST.

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




1. Disconnect the TIPM C3 harness connector.
2. Measure the resistance of the (D65) CAN C Bus (+) circuit between the TIPM C3 harness connector and the AWD harness connector.

Is the resistance below 5.0 ohms?

Yes

- Go To 6

No

- Repair the (D65) CAN C Bus (+) circuit for an open.
- Perform the AWD VERIFICATION TEST.

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




1. Measure the resistance of the (D64) CAN C Bus (-) circuit between the TIPM C3 harness connector and the AWD harness connector.

Is the resistance below 5.0 ohms?

Yes

- Replace and program the All Wheel Drive Control (AWD) Module.
- Perform the AWD VERIFICATION TEST.

No

- Repair the (D64) CAN C Bus (-) circuit for an open.
- Perform the AWD VERIFICATION TEST.
