Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  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  4.
  2. CHECK THE TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND

    1. Turn the ignition off to the lock position.
    2. Disconnect TCM harness connector and remove the TCM from the transmission.
    3. Measure the resistance of the internal Output Speed sensor between ground the appropriate terminal of the TCM transmission connector.

      Is the resistance above 100k Ohms?

      Yes 

      • Go To  3.

      No 

      • Remove the Transmission Side cover and inspect the internal harness for high resistance or intermittent short to ground. Refer to VALVE BODY, REMOVAL . If no short is found, replace the Transmission Temperature sensor.
      • Refer to STANDARD PROCEDURE  and perform the AW60T VERIFICATION TEST .
  3. CHECK THE TRANSMISSION TEMPERATURE SENSOR

    TYPICAL VALUES FOR TRANSMISSION TEMPERATURE SENSOR 
    TEMPERATURE  APPROXIMATE OHM 
    -30° C (-22° F) 44000 Ohms ± 6600
    10° C (50° F) 6455 Ohms ± 645
    110° C (230° F) 247 Ohms ± 16
    145° C (293° F) 111 Ohms ± 6
    1. Measure the resistance of the Transmission Temperature Sensor between the Transmission Temperature Signal circuit and the Transmission Temperature Sensor Ground circuit in the appropriate terminals of the TCM transmission connector.
    2. 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 in accordance with the Service Information. Refer to MODULE, TRANSMISSION CONTROL [EAB, DF1], REMOVAL .
      • Refer to STANDARD PROCEDURE  and perform the AW60T VERIFICATION TEST .

      No 

      • Remove the Transmission Side cover and inspect the internal harness for high resistance or intermittent short to ground. Refer to VALVE BODY, REMOVAL . If no trouble is found, replace the Transmission Temperature sensor.
      • Refer to STANDARD PROCEDURE  and perform the AW60T VERIFICATION TEST .
  4. 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.
      • Refer to STANDARD PROCEDURE  and perform the AW60T VERIFICATION TEST .

      No 

      • Test Complete.
