Vanity Lamp: Description and Operation

CIRCUIT OPERATION
The visor/vanity lamps are operated by a switch internal to the assembly Power for the lamps is provided by circuit M1 from the junction block. This is the Ignition-Off Draw (IOD) circuit and is protected by a 10 Amp fuse located in cavity 13 of the junction block. Power for the fuse is supplied on circuit A7 from the Power Distribution Center (PDC). Circuit A7 is protected by a 20 Amp fuse located in cavity G of the PDC. The M1 circuit is spliced and provides power to both lamps and is HOT at all times.

When the operator lifts the cover on the lamp, the switch CLOSES, completing a path to ground on circuit Z1. This circuit terminates at the Airbag Control Module (ACM) bracket.
