DTC (Gauge Control Module)

NOTE:

If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A - Initial Communication and DTC Checks .
If you have any loss of communication DTCs for the PCM, troubleshoot those DTCs first.

Problem verification

- 1. Clear the DTCs with the HDS.

Clear DTCs

- 2. Turn the vehicle to the OFF (LOCK) mode and then the ON mode.

- 3. Wait for at least 6 seconds.

- 4. Check for DTCs with the HDS.

Are any DTCs indicated?

YES

Go to step 2.

Intermittent failure, the system is OK at this time. Check for loose or poor connections.

Open wire check (F-CAN_L, F-CAN_H lines)

- 1. Turn the vehicle to the OFF (LOCK) mode.

- 2. Jump the SCS line with the HDS, and wait more than 1 minute.

SCS short

- 3. Disconnect the receiving control unit connector.

Gauge control module 32P connector

- 4. Disconnect the transmitting control unit connectors.

(Refer to the DTC code shown on the display, and then disconnect the connector(s) based on the instructions in the table below.)

PCM connector A (51P)
