Test C: The Courtesy Lamps Stay On Continuously

PINPOINT TEST C: THE COURTESY LAMPS STAY ON CONTINUOUSLY

Normal Operation
The smart junction box (SJB) monitors the door ajar switch status on circuits CPL26 (GN/VT) (LH front), CPL36 (GN)/CPL39 (YE) (LH rear), CPL31 (WH) (RH front) and CPL39 (YE) (RH rear). The door ajar switches are normally closed when the doors are closed. When the SJB determines a door is open, the SJB then controls the voltage side of the interior lamp on circuit VLN33 (GY/VT) to illuminate the interior lamp.
