Code C1210 GMC Description

As the wheel is rotated, the speed sensor produces an AC voltage that increases with wheel speed. The Electronic Brake Control Module (EBCM) uses the frequency of the AC signal to calculate the wheel speed. The speed sensor is connected to the EBCM by a twisted pair of wires. Twisting reduces noise susceptibility that may cause a Diagnostic Trouble Code (DTC) to be set. The DTC will be set when the right rear wheel speed is accelerating or decelerating beyond reasonable limits.
