U0161-LOST COMMUNICATION WITH COMPASS MODULE







- When Monitored:
With the ignition on.

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





1. CHECK FOR AN ACTIVE DTC

NOTE: Remove any electronic devices (laptop computers, cell phones) from the instrument panel.

NOTE: Before proceeding, check the compass variance and calibration.

1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Wait 30 seconds.
4. With the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- The condition that caused this code to set is not present at this time. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. (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 Instrument Cluster C2 harness connector.
3. Measure the resistance of the (D506) LIN BUS circuit.

Is the resistance below 10K ohms?

Yes

- Replace the Cluster.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Repair the (D506) LIN BUS circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

4. (F921) FUSED RUN RELAY OUTPUT CIRCUIT OPEN




1. Turn the ignition on.
2. Measure the voltage of the (F921) Fused Run Relay Output circuit at the Compass Module harness connector.

Is the voltage above 10 volts?

Yes

- Go To 5

No

- Repair the (F921) Fused Run Relay Output circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

5. (Z926) GROUND CIRCUIT OPEN




1. Turn the ignition off.
2. Measure the resistance between ground and the (Z926) Ground circuit at the Compass Module harness connector.

Is the voltage above 10K ohms?

Yes

- Replace the Compass Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Repair the (Z926) ground circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
