Normal Operation
When any door is open, the ajar switch opens the circuit to the smart junction box (SJB). In contrast, when the luggage compartment lid is opened, the switch closes the circuit to the SJB. The SJB monitors the ajar circuits, and based on the ajar status, the SJB will supply voltage to the courtesy lamps on circuit CLN26 (BU).

Possible Causes
- Circuit CLN26 (BU) short to voltage
- Circuit CLN28 (GN/BU) short to ground
- Circuit CPL26 (GN/VT) open
- Circuit CPL31 (WH) open
- Circuit CPL36 (GN) open
- Circuit CPL39 (YE) open
- Circuit CPL44 (YE/OG) short to ground
- Circuit GD126 (BK/WH) open
- Circuit GD139 (BK/YE) open
- Circuit GD171 (BK/GY) open
- Dimmer control switch
- Door ajar switch
- Luggage compartment lid ajar switch
- SJB
