Test I: The Ambient Lighting Is Inoperative
PINPOINT TEST I: THE AMBIENT LIGHTING IS INOPERATIVENormal Operation
When the ignition key is in the run or accessory position, the ambient lighting module supplies voltage and ground to the light emitting diodes (LEDs) located in the floor console cup holders and the front and rear footwells. The ambient lighting switch is used to cycle through the 7 color combinations or to turn the ambient lighting feature off. There are 3 different color (red, blue and green) LEDs housed within each LED assembly.
When the ignition key is in the run or accessory position, the ambient lighting switch and the ambient lighting module receives voltage through circuit CLN46 (BU) (shared with the electrochromatic mirror voltage supply circuit). Ground for the ambient lighting module is provided through circuit GD908 (BK). When the ambient lighting switch is pressed, voltage is routed to the ambient lighting module through circuit CLN54 (BN/YE), indicating a request for the module to cycle the ambient lighting to the next setting.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ambient lighting harness
- Ambient lighting switch
- Ambient lighting module
