This code means that the car's computer has detected a problem with the part that locks the charger plug into the car. It's like when a toy's battery cover won't close properly.
The P1C3D code is triggered when the vehicle's control module detects a high voltage condition in the circuit responsible for locking the battery charger coupler.
The Battery Charger Coupler Lock 'B' Control Circuit High code indicates that the voltage level in the control circuit for the charger coupler lock is higher than expected. This could be due to a short circuit, faulty wiring, or a malfunctioning control module.
• Unable to charge the vehicle
• Warning light on the dashboard
• Error message related to charging system
• Faulty charger coupler lock mechanism
• Wiring issues or short circuits in the control circuit
• Defective control module
Coupler: A device used to connect two parts together.
Control Module: An electronic device that manages various functions of the vehicle.
• Perform a visual inspection of the charger coupler lock and wiring.
• Use a multimeter to check for voltage levels in the control circuit.
• Test the control module functionality.
