The starter motor is attached to the cylinder block, at the joint between the transmission and the engine. The pinion gear of the starter motor protrudes through an aperture in the transmission housing, adjacent to the ring gear on the drive plate.
The starter motor has the motor located directly behind the pinion gear. The motor is geared directly to the pinion gear and is a pre-engaged type comprising a series wound motor and an overrunning clutch.
The starter motor has a permanent power supply via a fuse, located in the Battery Junction Box (BJB). The starter solenoid is connected to a power feed from the starter relay in the Engine Junction Box (EJB). The starter relay is controlled by the Powertrain Control Module (PCM). When the motor solenoid is energized it closes a high-current contact within the solenoid. The high-current contact supplies the starter motor with power from the startup battery.
