Circuit Description

WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) receives a variable voltage from the instrument panel lamp dimmer switch. The BCM uses this signal in order to vary the illumination level of the instrument panel lamps. The instrument panel dimming lamps output from the BCM is a pulse width modulated voltage supply used to light the instrument panel lamps. If a malfunction occurs in the instrument panel dimming lamps output circuit, this DTC is set.
