The cost of diagnosing the P15FB GMC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
The Electronic Brake Control Module (EBCM) monitors the brake pedal position sensor in order to provide emission related brake pedal position information to the Engine Control Module (ECM). The EBCM sends the information, via the serial data circuit, to the ECM in a continuously repeating series of 16 rolling counts, with each count assigned a value. When the ECM determines that too many of the counts have an incorrect value, the ECM sets DTC P15FB.
