B3624

DTC B3624

CIRCUIT DESCRIPTION
The body control module (BCM) monitors the steering wheel controls 2 switch signal circuit to determine the function. The MUTE/SEEK UP switch consists of a momentary contact switch that connects a series of resistors. Each switch selection corresponds to a specific resistance value. The BCM determines the switch selection by the voltage drop across the resistor. The BCM sets DTC B3624 when it detects a stuck MUTE/SEEK UP switch.
