Test K: The Ambient Lighting Is Inoperative

PINPOINT TEST K: THE AMBIENT LIGHTING IS INOPERATIVE

Normal Operation
The ambient lighting module and switch receive voltage from the accessory delay relay on circuit CBX07 (GN/RD), which is circuit CBP02 (GN) at the smart junction box (SJB). The ambient lighting module supplies voltage and ground to the LEDs, located in the floor console. The ambient lighting switch can cycle through 7 color combinations or turn the ambient lighting off by sending a voltage signal to the ambient lighting module through circuit CLN54 (BN/YE). There are 3 different color LEDs (red, blue, and green) housed within each LED assembly. Ground is provided to the module and switch through circuit GD116 (BK/VT), which is circuit GD908 (BK) at the module and switch.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ambient lighting switch
- Ambient lighting module
