Normal Operation
Under normal operation the PDB supplies constant power to the starter relay on circuit 1050 (LG/VT) through fuse 12 (50A). When the key is placed in the START position, with the vehicle in PARK or NEUTRAL, the TR sensor provides power on circuit 33 (WT/PK) and the PCM provides ground on circuit 461 (OR). The coil of the relay is energized and sends power to the starter motor on circuit 113 (YE/LB).
