Test J: DTCs B1141/B1142 - Convertible Top Full Down/Up Position Switch Circuit Failure

PINPOINT TEST J: DTCs B1141/B1142 - CONVERTIBLE TOP FULL DOWN/UP POSITION SWITCH CIRCUIT FAILURE

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 and provides ground to circuit 1558 (TN/BK). When the convertible top is in the full down position, the convertible top ajar switch closes and provides ground to circuit 700 (WH/VT). Ground is provided to the convertible top ajar switch 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. If DTC B1141 or B1142 is present, the rear quarter windows may still function during convertible top operation, but will not function when commanded by the window control switch.
