Starter System-Operation
When the ignition switch is turned to the START position, the starter relay switches power to the starter solenoid causing the starter motor to engage as long as
- the digital transmission range (TR) sensor is in PARK or NEUTRAL.
- the anti-theft system is operational.
Refer to SYSTEM WIRING DIAGRAMS (Freestar) or SYSTEM WIRING DIAGRAMS (Monterey) for schematic and connector information.
Normal Operation
Under normal operation, constant power is supplied to the starter relay on circuit 1050 (LG/VT). When the key is placed in the START position, with the vehicle in PARK or NEUTRAL, the TR sensor provides power to the starter relay coil on circuit 33 (WH/PK) and the PCM provides ground to the starter relay coil on circuit 1419 (LG/YE). When the coil of the relay is energized, it sends power to the starter motor on circuit 113 (YE/LB).
