Normal Operation
Power is supplied to the courtesy lamps through the smart junction box (SJB) fuse 9 (15A), and SJB fuse 25 (10A) for the demand lamps. When any door is opened, the ajar switch opens, signaling the SJB. The SJB monitors the ajar circuits, and based on the ajar status, the SJB supplies voltage to the courtesy lamps on circuit VLN33 (GY/VT). Ground is supplied through circuit GD133 (BK) for the courtesy lamps, and circuit GD126 (BK/WH) for the cargo lamp.
DTC B2A35 - is an on-demand DTC that sets when the SJB detects an open from the interior lighting circuit.
DTC B2A36 - is a continuous and on-demand DTC that sets when the SJB detects a short to ground from the interior lighting circuit.
