Circuit Description

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) receives a variable voltage signal from the instrument panel (I/P) dimmer switch requesting to illuminate the illumination lamps to a desired intensity. When this occurs, the BCM directly sends a variable voltage based on the I/P dimmer switch position on the instrument panel lamps dimming supply voltage circuit, controls illumination lamps dimming control circuit, and the LED dimming signal circuit.

Voltage for the instrument panel lamps dimming supply voltage circuit, controls illumination lamps dimming control circuit, and the LED dimming signal circuits is from the TBC 2A fuse in the instrument panel fuse block directly through the BCM to these circuits.
