Starting System
Starting system
1 tern Description
I 1 I lgnitionlstarter switch I
1 2 1 Starter relay I
1 3 1 Electric starter motor I
1 4 1 Powertrain control module (PCM) I
1 5 1 Sensor,- crankshaft position ( CKP) I
The purpose of the starting system is to turn the
engine crankshaft at a speed which enables the
engine to start.
The engine is started as follows:
Ignitionlstarter switch in position
Ill.
The starter relay is activated by the PCM .
The solenoid is supplied with voltage.
The solenoid engages the starter motor pinion
with the flywheel ring gear.
The solenoid applies battery current to the
starter.
The starter turns the crankshaft until the engine
starts. The key can then be released and it
automatically returns to position
I I.
The system incorporates the "Smart
StartingWstrategy. This makes starting faster and
protects the starter.
If the driver fails to release the key immediately
after the engine starts, the PCM interrupts
activation of the starter relay and thus switches off
the electric starter motor.
The speed signal provided by the CKP sensor is
used for monitoring the starting procedure.
