4.23.3 Starter relay

The starter relay is controlled by the ECM in response to a valid crank request signal when the vehicle is stationary and park or neutral are selected. A failure of the starter relay circuit will be registered if the starter relay drive signal from the ECM is on but the starter relay feedback indicates that the relay is off, or vice versa.
