•

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.

Possible Causes

INTERMITTENT DTC

(T752) STARTER CONTROL CIRCUIT SHORTED TO VOLTAGE

(T752) STARTER CONTROL CIRCUIT OPEN OR HIGH RESISTANCE

TOTALLY INTEGRATED POWER MODULE (TIPM)

POWERTRAIN CONTROL MODULE (PCM)

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)

Diagnostic Test

DTC IS ACTIVE

Ignition on, engine not running.

With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes

>> Go to 2

>> Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. (Refer to 9 - ENGINE -

DIAGNOSIS AND TESTING)

(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 volt-

age.

Perform the PCM Verification Test Ver. 1 (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING).

>> Go to 3

(T752) STARTER CONTROL CIRCUIT OPEN OR HIGH RESISTANCE

Turn the ignition off.

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

>> Repair the (T752) Starter Control circuit for an open circuit

or high resistance.

Perform the PCM Verification Test Ver. 1 (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING).

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

>> Replace the Totally Integrated Power Module (TIPM) in

accordance with the Service Information.

Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

>> Go to 5

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.

Refer to any Technical Service Bulletins that may apply.

Were any problems found?

Yes

>> Repair as necessary.

Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

>> Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information.

Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

•

When Monitored:
With the ignition on.

•

Set Condition:
When secondary software determines that the requested output is not being achieved by the engine for a
period of time. ETC lamp will flash.

Possible Causes

INTERMITTENT DTC

POWERTRAIN CONTROL MODULE (PCM)

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)

Diagnostic Test

DTC IS ACTIVE

NOTE: If any other DTCs are set, they must be diagnosed and repaired before continuing this test.

NOTE: An intermittent loss of power to the PCM without performing an ETC Relearn procedure may cause
this DTC to set.

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.
Turn the ignition on.

With the scan tool, Clear DTCs in the Powertrain Control Module (PCM).

Verify the Powertrain Control Module (PCM) is at the latest calibration (flash level). If necessary, update the Pow-
ertrain Control Module (PCM) in accordance with the Service Information.

Start the engine and allow it to reach operating temperature.

Increase engine speed by pressing the accelerator pedal. Do not exceed 3500 rpm.

With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes

>> Go to 2

>> Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. (Refer to 9 - ENGINE -

DIAGNOSIS AND TESTING)

POWERTRAIN CONTROL MODULE (PCM)

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Throttle Body 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.

Refer to any Technical Service Bulletins that may apply.

Were any problems found?
