Starter Relay Circuit
SMALL | MEDIUM | LARGE

Circuit Description

The starter lockout relay is controlled by the Electronic Control Module (ECM) through the starter lockout relay signal circuit. The relay prevents the starter from being engaged when the engine is running. The relay return circuit is dependent on Original Equipment Manufacturer (OEM) wiring. It is wired to chassis or block ground. Consult the OEM wiring diagram for return circuit details.

Component Location

The starter lockout relay is installed by the vehicle OEM. See the OEM service manual for exact location.

Shop Talk

The ECM monitors the voltage level on this circuit. If it detects a voltage when the signal is commanded off, it records this fault code. This fault can be caused by:

  • Open circuit in the starter lockout relay, OEM harness, or connectors
  • Short circuit to a voltage source in the OEM harness or relay.

Cautions and Warnings

 CAUTION 

To reduce the possibility of damaging a new ECM, all other active fault codes must be investigated prior to replacing the ECM.
 CAUTION 

To reduce the possibility of pin and harness damage, use the following test leads when taking a measurement:
Part Number 3822758 – male Deutsch/AMP/Metri-Pack test lead
Part Number 3822917 – female Deutsch/AMP/Metri-Pack test lead.
