DESCRIPTION & OPERATION
| WARNING | Deactivate air bag system before performing any service operation. See appropriate AIR BAG RESTRAINT SYSTEMS article. Do not apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy. |
When ignition switch is turned to START position a 12-volt signal is sent to PCM Ignition Crank Sense circuit. PCM verifies that transmission is in Park or Neutral position. PCM then grounds START-1 relay coil, completing circuit which energizes relay. When starter relay is energized, contacts close sending battery voltage to starter solenoid "S" terminal. This causes solenoid pull-in windings to move plunger and shift lever, which engages pinion gear with engine flywheel ring gear. Movement of plunger also closes main solenoid contacts, applying full battery voltage directly to starter motor, cranking engine. (Scheme 1)
When engine starts, pinion overrun clutch protects armature from excessive speed produced by engine. When ignition switch is released from START position, plunger return spring disengages pinion gear from flywheel and opens main solenoid contacts.
The PG-260M and PG-260L starter motors are non-serviceable and must be replaced as a single unit to repair. For starter to engine application, see STARTER APPLICATION table.
| Engine | Starter |
