| WARNING | On vehicles equipped with airbags, refer to AIR BAG RESTRAINT SYSTEMS before attempting steering wheel, steering column, or instrument panel component diagnosis or service. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury. |
DESCRIPTION
The starter is a permanent magnet starter motor. The fields have six permanent magnets. A planetary gear train transmits power between starter motor and pinion shaft. The starter provides mechanical torque to rotate the crankshaft at an RPM (crank speed) necessary for self-sustained spark/ignition.
Scheme 1
Scheme 2
- Disconnect and isolate the battery negative cable. (Scheme 1)
- Raise vehicle on hoist.
- Remove starter bolts. (Scheme 2)
- Remove starter assembly.
- Disengage latch and remove solenoid connector from starter assembly.
- Remove battery positive connector from starter assembly. It is not necessary to remove the alternator output lead from the connector.
The Starter Relay is a micro relay located in the Power Distribution Center (PDC), positioned in the left front corner of the engine compartment.
OPERATION
As battery power is applied to the relay from the ignition switch, battery power is applied to the starter motor through the relay to the starter solenoid.
The Starter Solenoid is mounted directly to the Starter Motor.
The Starter Solenoid is a switching device used to activate the high amperage starter motor circuit from a low amperage control circuit.
