For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
With the ignition on and the Starter Relay command off.

- Set Condition:
The Engine Control Module (ECM) detects that the Engine Starter Motor Relay Control circuit is shorted to ground for 5.0 seconds.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Diagnostic Test

1. DTC IS ACTIVE
Ignition on, engine not running.
With the scan tool, Clear DTCs in the Engine Control Module (ECM).
Crank the engine for five seconds.
With the scan tool, select View DTCs.
Is the status Active for this DTC?

Yes

- Go To 2

No

- Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure.Component Tests and General Diagnostics

2. ENGINE STARTER MOTOR RELAY CONTROL CIRCUIT SHORTED TO GROUND
Turn the ignition off.
Disconnect the Starter Relay.
Disconnect the Engine Control Module (ECM) connector.
Measure the resistance between ground and the Engine Starter Motor Relay Control circuit in the Starter Relay connector.
Is the resistance below 1000 ohms?

Yes

- Repair the Engine Starter Motor Relay Control circuit for a short to ground.
- Perform the ECM Verification Test Ver. 1. Verification Tests

No

- Go to 3

3. ENGINE STARTER MOTOR RELAY CONTROL CIRCUIT OPEN OR HIGH RESISTANCE
Measure the resistance of the Engine Starter Motor Relay Control circuit between the Starter Relay connector and the Engine Control Module (ECM) harness connector.
Is the resistance below 10.0 ohms?

Yes

- Go to 4

No

- Repair the Engine Starter Motor Relay Control circuit for an open circuit or high resistance.
- Perform the ECM Verification Test Ver. 1. Verification Tests

4. STARTER RELAY
Connect the Engine Control Module (ECM) connector.
Install a substitute Starter Relay in place of the vehicle's Starter Relay.
Turn the ignition on.
With the scan tool, Clear DTCs.
Crank the engine for five seconds.
With the scan tool, select View DTCs.
Is the status Active for this DTC?

Yes

- Go to 5

No

- Replace the Starter Relay.
- Perform the ECM Verification Test Ver. 1. Verification Tests

5. ENGINE CONTROL MODULE (ECM)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Starter Relay and the Engine Control Module (ECM).
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals.
Search for any Technical Service Bulletins that may apply.
Were any problems found?

Yes

- Repair as necessary.
- Perform the ECM Verification Test Ver. 1. Verification Tests

No

- Replace the Engine Control Module (ECM).
- Perform the ECM Verification Test Ver. 1. Verification Tests
