Lights On Chime

The BCM will activate an audible warning as a reminder that the headlamps are left on when exiting the vehicle with the ignition switch in the off position. The lights on warning sounds at the rate of 150 pulses per minute (fast rate chime) until the headlamp switch in turned off. The BCM receives a signal from the headlamp and panel dimmer switch via the headlamp relay. The BCM activates the lights on warning chime when the following occurs:
^ The ignition is OFF.
^ The park lamp switch input is active.
^ The dimming potentiometer input is not in a maximum dimming state.
