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 dimming lamps to a desired intensity. When this occurs, the BCM directly sends a pulse width modulated (PWM) voltage based on the I/P dimmer switch position on the light emitting diode (LED) dimming supply circuit, controls illumination lamps dimming control circuit, and the instrument panel lamps dimming supply voltage circuit.

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