This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the part of the car that helps charge the battery. It's like a switch that isn't working right, so the battery might not charge properly.
The code indicates an issue with the control circuit for the negative contactor in the battery charging system. This circuit is responsible for managing the flow of electricity during charging.
P2D67 is triggered when the vehicle's onboard diagnostics system detects a low voltage or an open circuit condition in the control circuit for the negative contactor C of the battery charging system. This contactor is crucial for ensuring proper electrical flow and charging of the vehicle's battery.
