1043-00 CAN BUS COMMUNICATION GENERAL MALFUNCTION





- When Monitored: With the ignition on.

- Set Condition: CAN Bus communication failure between the Instrument Cluster and the CAN Bus network.





Diagnostic Test

1. MEASURE THE RESISTANCE OF THE CAN C BUS (+) CIRCUIT





Turn the ignition off.

Disconnect the Instrument Cluster harness connector.

Disconnect the harness connectors of the other modules on the CAN Bus network.

NOTE: Check connectors - Clean/repair as necessary.

Measure the resistance of the CAN C Bus (+) circuit from the Instrument Cluster harness connector to the harness connectors of the other modules on the CAN Bus network.

Is the resistance below 1.0 ohm?

Yes

- Go to 2

No

- Repair the CAN C Bus (+) circuit for an open.
- Perform ABS VERIFICATION TEST. ABS Verification Test

2. MEASURE THE RESISTANCE OF THE CAN C BUS (-) CIRCUIT





With the ignition off.

Measure the resistance of the CAN C Bus (-) circuit from the Instrument Cluster harness connector to the harness connectors of the other modules on the CAN Bus network.

Is the resistance below 1.0 ohm?

Yes

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

No

- Repair the CAN C Bus (-) circuit for an open.
- Perform BODY VERIFICATION TEST. ABS Verification Test
