Normal Operation
The smart junction box (SJB) monitors the status of the convertible top through circuits 1558 (TN/BK) and 700 (WH/VT). When the convertible top is in the full up position, the convertible top ajar switch closes to ground circuit 1558 (TN/BK). When the convertible top is in the full down position, the convertible top ajar switch closes to ground circuit 700 (WH/VT). Ground is provided through circuit 1205 (BK). DTC B1141 sets if the convertible top ajar switch on-demand self-test is run with the convertible top not in the full down position. DTC B1142 sets if the convertible top ajar switch on-demand self-test is run with the convertible top in the full up position.

Possible Causes
- circuit 700 (WH/VT) short to voltage, short to ground, or open
- circuit 1205 (BK) open
- circuit 1558 (TN/BK) short to voltage, short to ground, or open
- convertible top ajar switch
- SJB
