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.
