U0161-LOST COMMUNICATION WITH COMPASS MODULE





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on.

- Set Condition:
The Cluster does not receive information from the Compass Module.





1. CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK THE VOLTAGE OF THE (D506) LIN BUS CIRCUIT




1. Turn the ignition off.
2. Disconnect the Compass Module harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (D506) LIN BUS circuit.

Is the voltage above 5 volts?

Yes

- Go To 4

No

- Go To 3

3. (D506) LIN BUS CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Cluster C1 harness connector.
3. Measure the resistance of the (D506) LIN BUS circuit.

Is the resistance below 10K Ohms?

Yes

- Replace the Cluster. Instrument Cluster - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (D506) LIN BUS circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. (F921) IGNITION RUN CIRCUIT OPEN




1. Turn the ignition on.
2. Measure the voltage of the (F921) Ignition Run circuit.

Is the voltage above 10 volts?

Yes

- Go To 5

No

- Repair the (F921) Ignition Run circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. (Z923) GROUND CIRCUIT OPEN




1. Turn the ignition off.
2. Measure the resistance between ground and the (Z923) Ground circuit.

Is the resistance below 10K Ohms?

Yes

- Replace the Compass Module. Compass Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (Z923) ground circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
