Starter Relay: Description and Operation

The starter interrupt relay consists of the following:
- Pull-in coil
- Contacts

When the ignition switch is in the START position and the selector lever is in NEUTRAL or PARK:
- Current passes from the Transmission Range (TR) sensor to the pull-in coil.
- Pull-in coil is activated and pulls the contacts together.
- Current passes through the starter relay from the engine compartment power distribution box to the starter solenoid.

The starter interrupt relay is energized by the anti-theft controller and opens the starter circuit.
