Code B2587 GMC Description

The Body Control Module (BCM) provides the steering column control function which allows the column to be electronically locked or unlocked. The BCM provides three outputs, steering column lock, steering column unlock, and a steering column lock relay control. The BCM can apply a ground or battery output on the steering column lock or steering column unlock depending on the desired steering column lock motor position. The BCM uses the feedback switch in order to monitor the motor position and determine if the commanded position was accomplished. The Diagnostic Trouble Code (DTC) sets when the BCM detects an internal malfunction, an open or a short to ground, in the steering column lock circuit.
