Turn Signals

Movement of the turn signal stalk up or down will activate the Left/Right turn signals with the ignition on. Placement of the stalk switch up or down with the ignition off will activate parking lights only on the side requested. Flashing of the turn signals is controlled by the BC1.

The left hand and right hand direction indicator lamps in the instrument cluster will always be synchronized with the respective vehicle direction indicators. The Body Control Module (BC1) controls operation of the indicator LED in the cluster via the K-bus.
