Normal Operation
The battery junction box (BJB) supplies voltage to the roof opening panel motor through circuit 931 (OG). The central junction box (CJB) supplies voltage to the roof opening panel switch (part of the overhead console) through circuit 964 (DB/LG) when the ignition switch is in the ON or ACC position. Ground to the overhead console is supplied through circuit 676 (PK/OG). When the roof opening panel control switch is moved to the open position and released it connects circuit 964 (DB/LG) to circuit 1174 (WH/RD) for open. When the roof opening panel control switch is moved to the close position and released it connects circuit 964 (DB/LG) to circuit 1175 (TN/RD) for close. Ground to the roof opening panel motor is supplied through circuit 57 (BK).
