Code B2815 Chevrolet Description

The Steering Wheel Controls are momentary contact switches that connect a series of resistors so that each switch selection corresponds to a fixed resistance value. The Body Control Module (BCM) determines which switch has been pressed by the voltage drop across the corresponding resistance value. The BCM supplies voltage to the steering wheel controls through the rear wiper/washer switch supply voltage circuit. The BCM monitors the switch voltage on the remote radio control signal circuit. The Diagnostic Trouble Code (DTC) sets when the BCM detects a switch voltage that is higher than normal.
