Normal Operation
Under normal operation, the battery junction box (BJB) supplies constant power to the starter relay on circuit 32 (RD/LB) through fuse F105 (30A). Constant power is also supplied to fuse F1 (30A) that powers C250-9, circuit 1050 (LG/VT) for ignition voltage. When the key is placed in the START position with the vehicle in PARK or NEUTRAL, the transmission range (TR) sensor provides power on circuit 33 (WH/PK) and the powertrain control module (PCM) provides ground on circuit 3405 (GY/RD), activating the starter motor.

Possible Causes
- Battery
- Starter motor
