P0616-STARTER CONTROL CIRCUIT LOW

For a complete wiring diagram, refer to the Wiring Information.

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

- Set Condition:
The Powertrain Control Module (PCM) detects that the starter relay control circuit is shorted to ground.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

Diagnostic Test

1. DTC IS ACTIVE
1. Turn the ignition on.
2. With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes

- Go To 2

No

- Perform the INTERMITTENT CONDITION diagnostic procedure. Intermittent Condition Test.

2. STARTER RELAY
1. Turn the ignition off.
2. Install a known good relay.

Does the engine start?

Yes

- Replace the Starter Relay.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Go To 3

3. CHECK THE (T750) STARTER RELAY CONTROL CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the PCM C1 harness connector.
3. Remove the Starter Relay.
4. Measure the resistance between ground and the (T750) Starter Relay Control circuit at the PCM C1 harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Repair the (T750) Starter Relay Control circuit for a short to ground.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Go To 4

4. POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the relay and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Perform any Technical Service Bulletins that may apply.

Were any problems found?

Yes

- Repair as necessary.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Replace and program the Powertrain Control Module (PCM). .
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.
