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.

Conditions for Running the DTC
Ignition is in RUN.

Conditions for Setting the DTC
Steering wheel controls 2 signal circuit remains in the same state for 1 minute

Action Taken When the DTC Sets
MUTE/SEEK UP switch remains in the last selected position

Conditions for Clearing the MIL/DTC
^ The DTC becomes history when the fault is no longer present.
^ A History DTC clears after 100 malfunction free ignition cycles.
^ The BCM module receives a clear code command from the scan tool.
