Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Starting System: Description
Bosch, Melco and Mitsubishi starters use a planetary gear train that transmits power from starter motor to pinion shaft. Six permanent magnets (Bosch and Melco starters) or 4 permanent magnets (Mitsubishi starters) are used, eliminating potential field wire-to-frame short circuits.
Nippondenso starter is a 4-field, 4-brush, 12-volt motor with a solenoid mounted within housing. Diesel models uses a conventional gear set. Starter has a 2-to-1 reduction gear set in a die cast aluminum housing, except diesel models. Starter has serviceable gear and clutch assembly only. If starter solenoid fails, entire starter motor must be replaced.
All models use a starter relay in starter circuit between battery and starter solenoid terminal. Automatic Transmission (A/T) equipped vehicles use a Park/Neutral Position (PNP) switch or a Transmission Range (TR) sensor to complete circuit or signal Powertrain Control Module (PCM). Manual Transmission (M/T) equipped vehicles use a clutch pedal position switch to complete circuit or signal PCM. See WIRING DIAGRAMS .
