Ash Tray Lamp: Description and Operation

CIRCUIT OPERATION
The ash receiver lamp receives power on the E2 circuit from the Body Control Module (BCM). This circuit is HOT when the operator has turned the headlamp switch to the PARK or ON position. Lamp intensity is controlled by the input of the dimmer switch to the BCM on circuit E19.

Ground for the lamp is provided by the Z1 circuit. This circuit terminates at the instrument panel left side cowl after passing through the ground joint in the junction block.
