This code means there's a problem with the part of the car that helps manage the battery's charging. 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 can affect the battery's ability to charge efficiently.
The P2D65 code is triggered when the Engine Control Module (ECM) detects an open or malfunction in the control circuit of the negative contactor in the battery charging system. This contactor is responsible for managing the flow of electricity to and from the battery, ensuring proper charging and discharging cycles.
