This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in your car that helps manage charging is not working right. It's like a battery checker that isn't reading the battery correctly.
The P1C4D code indicates that the voltage reading from the crash clamp voltage sensor in the universal charger extension control module is lower than expected.
This diagnostic trouble code (DTC) is triggered when the universal charger extension control module detects a voltage level from the crash clamp voltage sensor that is below the specified range. This could be due to a sensor malfunction, wiring issues, or a fault in the control module itself.
• Charging system warning light on
• Reduced charging efficiency
• Possible inability to charge the vehicle
• Faulty crash clamp voltage sensor
• Wiring issues or poor connections
• Defective universal charger extension control module
