Starter Relay
Double Start Override is a feature that prevents the starter from operating if the engine is already running.This feature is accomplished with software only.
- There was no hardware added because of this feature.
- To incorporate the unique feature of Double Start Override, it was necessary to use the PCM (software) to control the starter circuit.
To use the PCM it was necessary to separate the starter relay coil ground from the park neutral switch.
- The starter relay ground is now controlled through Pin 60 of the PCM.
- This allows the PCM to interrupt the ground circuit if other inputs tell it that the engine is turning.
If the starter system is operating properly, it can be assumed that the override protection is also working.
