Code C0242 2014 Chevrolet Silverado Description

The Electronic Brake Control Module (EBCM) and the Engine Control Module (ECM) simultaneously control the traction control. The Electronic Brake Control Module sends a serial data message to the Engine Control Module requesting torque reduction. When certain Engine Control Module DTCs are set, the Engine Control Module will not be able to perform the torque reduction for traction control. A serial data message is sent to the Electronic Brake Control Module indicating that traction control is not allowed. The Diagnostic Trouble Code (DTC) engine control module detects a fault that prevents it from performing a traction control function and sends a serial data message to the electronic brake control module indicating that torque reduction is not allowed.
