Possible Causes
- Signal plausibility failure (voltage out of range)
NOTE:
Circuit reference - DCM R/L -
- Refer to the appropriate system wiring diagrams and check headlamp leveling motor circuits for failure. Disconnect one headlamp connector, clear DTC and re-test. If DTC cleared, suspect headlamp leveling control module or circuits to the disconnected side of the failure. If DTC remains, reconnect first headlamp and disconnect second, clear DTC and re-test. If DTC cleared, suspect headlamp leveling control module or circuits to the disconnected side of the failure. If DTC remains, suspect common circuits of the failure. Refer to the appropriate system wiring diagrams and check as required
