Starting System: Operation

When ignition key is put into ignition switch, transponder sends a code to Central Electronics With Anti-Theft Alarm (TWICE) module which grounds starter relay actuating coil. As ignition is turned to start position, starter relay operates and circuit to solenoid terminal No. 50 closes. Solenoid engages pinion with ring gear on engine's flywheel and closes a switch so starter motor commutator is supplied with power via slip brushes from terminal No. 30.

After engine start and engine speed exceeds starter motor RPM, pinion is disengaged from its shaft via a freewheel, preventing starter motor from over revving. Releasing ignition key breaks starting circuit and operating circuit to solenoid, causing spring to return pinion to its rest position.
