Verify 12 volts power on the Red wire, and ground on the Black wire, at the 2-pin connector to the Electronic Brake Control Module (EBCM). Disconnect the plug from the bottom of the EBCM going to the motor. Then power and ground those wires and verify that the motor runs and how it sounds. If the motor runs and sounds fine, then the EBCM has to be replaced. If the motor does not run, replace the motor and retest to see if the code returns.
This code pertains to loss of communication from the EBCM, not a malfunction of the EBCM, and the factory repair involves re-grounding the EBCM...
