Code C1205 Ford Description

The C1205 Ford diagnostic trouble code (DTC) indicates an issue with the ABS Rear Dump Valve Circuit being shorted to ground. The ABS (Anti-lock Braking System) Rear Dump Valve is responsible for releasing brake pressure to prevent wheel lock-up during sudden braking or slippery road conditions. When this circuit is shorted to ground, it means that there is an unintended connection between the dump valve and the vehicle's chassis or ground, which can disrupt the proper functioning of the ABS system.
