P0617-STARTER CONTROL CIRCUIT HIGH





For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
With the engine running and battery voltage greater than 10.4 volts.

- Set Condition:
The PCM detects that the starter control circuit is shorted high.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.Initial Inspection and Diagnostic Overview

Diagnostic Test

1. DTC IS ACTIVE
Attempt to start the engine. If the engine will not crank, turn the ignition switch to the crank position for 5 seconds.

WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death.

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.Checking For An Intermittent DTC

2. (T752) STARTER CONTROL CIRCUIT SHORTED TO VOLTAGE




Turn the ignition off.
Disconnect the Totally Integrated Power Module (TIPM) connector.
Disconnect the Powertrain Control Module (PCM) connector.
Turn the ignition on.
Measure the voltage of the (T752) Starter Control circuit in the Totally Integrated Power Module (TIPM) harness connector.
Is there any voltage present?

Yes

- Repair the (T752) Starter Control circuit for a short to voltage.
- Perform the PCM Verification Test Ver. 1Powertrain Verification Test.

No

- Go to 3

3. (T752) STARTER CONTROL CIRCUIT OPEN OR HIGH RESISTANCE




Turn the ignition off.

NOTE: When checking circuits at the Powertrain Control Module (PCM), be careful not to damage or distort the connector terminals. Improper measurement technique could result in poor pin to terminal contact.

Measure the resistance of the (T752) Starter Control circuit between the Totally Integrated Power Module (TIPM) harness connector and the Powertrain Control Module (PCM) harness connector.
Is the resistance below 5.0 ohms?

Yes

- Go to 4

No

- Repair the (T752) Starter Control circuit for an open circuit or high resistance.
- Perform the PCM Verification Test Ver. 1Powertrain Verification Test.

4. TOTALLY INTEGRATED POWER MODULE (TIPM)




Connect the Powertrain Control Module (PCM) connector.
Turn the ignition on.
Using a 12 volt test light connected to 12 volts, check the (T752) Starter Control circuit in the Totally Integrated Power Module (TIPM) harness connector.

NOTE: The test light should not be illuminated.

While monitoring the test light, move the ignition to the start position.

NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.

Is the test light not illuminated with the ignition in the run position and illuminated and bright with the ignition in the start position?

Yes

- Go to 5

No

- Go to 6

5. TOTALLY INTEGRATED POWER MODULE (TIPM)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Totally Integrated Power Module (TIPM) and the Powertrain Control Module (PCM).
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 PCM Verification Test Ver. 1Powertrain Verification Test.

No

- Replace the Totally Integrated Power Module (TIPM).
- Perform the PCM Verification Test Ver. 1Powertrain Verification Test.

6. POWERTRAIN CONTROL MODULE (PCM)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Totally Integrated Power Module (TIPM) and the Powertrain Control Module (PCM).
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 PCM Verification Test Ver. 1Powertrain Verification Test.

No

- Replace and program the Powertrain Control Module (PCM).
- Perform the PCM Verification Test Ver. 1Powertrain Verification Test.
