For a complete Instrument Cluster Circuit Diagram,Schematics and Diagrams.

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. Instrument Cluster - Removal.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

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