Non-Dimming Panel Lamps Circuit

WARNING: This page is about a different variant/trim than selected.

The non-dimming panel lamps circuit actually includes several circuits. These circuits control the backlighting of the heater-air conditioner controls, the window controls, the upper and lower instrument panel switch pods, the steering wheel switches and the automatic transmission gear selector bezel. All lamps in the non-dimming panel lamps circuits are provided a path to ground at all times through a hard wired ground circuit. These lamps are illuminated by outputs of the BCM using internal high side drivers through the non-dimming panel lamps circuits.

The Instrument Panel Cluster (IPC) and the radio use electronic backlights without dimmer messages from the BCM to control the illumination intensity of their own back lighting and controls.
