Normal Operation
In normal operation, voltage from the battery junction box (BJB) fuse 7 (60A) is supplied to the ignition switch through circuit 1050 (LG/VT). When the ignition switch is placed in the START position, voltage is supplied through circuit 33 (WH/PK) to the central junction box (CJB) fuse 33 (10A). Voltage is supplied from the CJB to the starter relay through circuit 1093 (TN/RD). The starter relay is supplied ground from the powertrain control module (PCM) through circuit 1419 (LG/YE). Voltage is supplied at all times to the starter motor from the battery, circuit 2037 (RD). The starter relay has voltage supplied at all times from BJB fuse 18 (60A), circuit 1523 (DG). When the starter relay is energized, voltage supplied to the starter relay is sent to the starter motor solenoid through circuit 113 (YE/LB).
