Transmission Control Module (TCM) - AS68RC






P0713-TRANSMISSION TEMPERATURE SENSOR 1 HIGH





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

Theory of Operation

The Transmission Oil Temperature Sensor is used to determine shift schedule selection. Transmission Oil Temperature is also used in TCC operation.

- When Monitored:
Continuously with the ignition on and the engine running.

- Set Condition:
The Diagnostic Trouble Code (DTC) will set if the monitored Transmission Temperature Sensor Signal circuit is greater than -40° C (-40° F) for more than 500 ms.





Always perform the AS68RC Pre-Diagnostic Troubleshooting procedure before proceeding. AS68RC Pre-Diagnostic Troubleshooting Procedure

1. CHECK IF DTC IS CURRENT
1. Using the scan tool, read TCM DTCs.
2. Record the Environmental Data and any DTCs.
3. Clear DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. Read TCM DTCs.

Did the DTC reset?

Yes

- Go To 2

No

- Go To 6

2. CHECK THE (T54) TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE




1. Turn the ignition off to the lock position.
2. Disconnect the TCM C1 harness connectors.
3. Disconnect the Transmission Solenoid Assembly C1 harness connector.
4. Ignition on, engine not running.
5. Measure the voltage of the (T54) Transmission Temperature Sensor Signal circuit in the TCM C1 harness connector.

Is the voltage above 0.5 of a volt?

Yes

- Repair the (T54) Transmission Temperature Sensor Signal circuit for a short to voltage.
- Perform AS68RC TRANSMISSION VERIFICATION TEST AS68RC Transmission Verification Test.

No

- Go To 3

3. CHECK THE (T54) TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT FOR AN OPEN




1. Measure the resistance of the (T54) Transmission Temperature Sensor Signal circuit between the PCM C2 harness connector and the Transmission Solenoid Assembly harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Go To 4

No

- Repair the (T54) Transmission Temperature Sensor Signal circuit for an open.
- Perform AS68RC TRANSMISSION VERIFICATION TEST AS68RC Transmission Verification Test.

4. CHECK THE (T820) SENSOR GROUND CIRCUIT FOR AN OPEN




1. Measure the resistance of the (T820) Sensor Ground circuit between the TCM C3 harness connector and the Transmission Solenoid Assembly C1 harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Go To 5

No

- Repair the (T820) Sensor Ground circuit for an open.
- Perform AS68RC TRANSMISSION VERIFICATION TEST AS68RC Transmission Verification Test.

5. CHECK THE TRANSMISSION TEMPERATURE SENSOR









1. Turn the ignition off to the lock position.
2. Reconnect the Transmission Solenoid harness connector.
3. Disconnect the TCM C3 harness connector.

NOTE: Check connectors - Clean/repair as necessary

4. Measure the resistance of the Transmission Temperature Sensor between the (T54) Transmission Temperature Signal circuit and the (T820) Sensor Ground circuit in the TCM C3 harness connector.
5. Using the chart at the chart above, compare the Temperature Sensor temperature to the correlating resistance value.

Is the resistance within the specified range when the sensor is at the given temperature?

Yes

- Using the schematics as a guide, check the Transmission Control Module (TCM) pins, terminals, and connectors for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the TCM.
- Perform AS68RC TRANSMISSION VERIFICATION TEST AS68RC Transmission Verification Test.

No

- Remove the Transmission Oil Pan and inspect the internal Transmission harness, pins, terminals, and connectors for corrosion, damage, or terminal push out. If no problems are found, replace the Transmission Temperature Sensor.
- Perform AS68RC TRANSMISSION VERIFICATION TEST AS68RC Transmission Verification Test.

6. CHECK WIRING AND CONNECTORS
1. The conditions necessary to set the DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. Check for any Service Bulletins that may apply.

Were there any problems found?

Yes

- Repair as necessary.
- Perform AS68RC TRANSMISSION VERIFICATION TEST AS68RC Transmission Verification Test.

No

- Test Complete.
