Test F: The Courtesy Lamps Are Inoperative - From The Dimmer Switch
PINPOINT TEST F: THE COURTESY LAMPS ARE INOPERATIVE - FROM THE DIMMER SWITCH
Normal Operation
The smart junction box (SJB) monitors the instrument panel dimmer switch status on circuit CLN28 (GN/BU) to determine if the courtesy lamps are
requested. When the instrument panel dimmer switch is rotated to the dome detent, ground is supplied to circuit CLN28 (GN/BU). Based on the
dimmer switch status, the SJB supplies voltage to the courtesy lamps through circuit VLN33 (GY/VT).
