C0243 Pontiac Description

The Electronic Brake Control Module (EBCM) sends a Engine Drag Control (EDC) request via a dedicated data line. The Powertrain Control Module (PCM) supplies a pull up voltage of 5 volts that the EBCM switches to ground to create the signal. The EBCM receives a serial data message from the PCM indicating that the EDC circuit has failed.
