Code C0240 Buick Description

The Powertrain Control Module (PCM) and the Electronic Brake Control Module (EBCM) communicate on the serial data link, whenever the ignition is ON. The EBCM receives a serial data message stating that the PCM has lost the ability to reduce engine torque. A requested torque signal malfunction is only one possible cause for the PCM to lose the ability to perform traction control. DTC C0240 may set due to engine overheating, throttle actuator control failure, loss of ignition timing control by the PCM, etc.
