This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble with a part that helps lock the charger in place when charging the car's battery. It's like when a plug doesn't fit right into an outlet.
The P1C3C code indicates a problem with the electrical circuit that controls the locking mechanism for the battery charger coupler, specifically that the circuit is reading a low voltage.
The P1C3C code is triggered when the Powertrain Control Module (PCM) detects a low voltage condition in the control circuit for the Battery Charger Coupler Lock 'B'. This could be due to an electrical fault such as a short to ground, an open circuit, or a failed component within the system.
• Charging issues
• Warning light on the dashboard
• Inability to charge the vehicle
• Faulty battery charger coupler lock
• Damaged wiring or connectors
• Failed control module
PCM: Powertrain Control Module
Coupler: A device used to connect two parts together
• Inspect the battery charger coupler lock for damage.
• Check the wiring and connectors for signs of wear or damage.
• Test the control circuit for proper voltage levels.
• Replace the faulty battery charger coupler lock.
• Repair or replace damaged wiring or connectors.
• Replace the control module if necessary.
• Multimeter
• OBD-II scanner

Moderate
• Chevrolet Volt
• Nissan Leaf
• Tesla Model S
• Regularly inspect charging equipment.
• Ensure connectors are clean and secure.
• Avoid exposure to extreme weather conditions.
Electrical Circuit Issue
• Do not attempt to charge the vehicle until the issue is resolved.
• Contact a professional mechanic for diagnosis and repair.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been more common with the rise of electric vehicles and plug-in hybrids, reflecting the increased complexity of charging systems.
Moderate – It should be addressed soon to ensure the vehicle can be charged properly.
Ensure all repairs are conducted by a qualified professional to prevent electrical hazards.
• Vehicle in Park
• Charging cable connected
The battery charger coupler lock is typically located near the charging port of the vehicle.
Q: Can I drive my car with this code?
A: Yes, but you may not be able to charge the vehicle until the issue is fixed.
Q: Is this a common problem?
A: It can occur in electric and hybrid vehicles, especially if the charging system is frequently used.
