Diagnostic Test

  1. CHECK TO SEE IF THE DTC IS ACTIVE 
    1. With the scan tool, read Transmission DTCs.

      Is the status Active or is the Starts Since Set counter 2 or less for this DTC?

      Yes 

      • Go To  2.

      No 

      • Go To  6.
  2. CHECK THE (T314) A, (T315) B, (T316) C, AND (T317) D STEP MOTOR CONTROL CIRCUIT(S) FOR A SHORT TO VOLTAGE

    1. Turn the ignition off to the lock position.
    2. Disconnect the TCM C1 and C2 harness connectors.
    3. Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
    4. Ignition on, engine not running.
    5. Measure separately the voltage of the (T314) A, (T315) B, (T316) C, and (T317) D Step Motor Control circuits.

      Is the voltage above.05 of a volt for any of the Step Motor Control circuits?

      Yes 

      • Repair the (T314) A, (T315) B, (T316) C, and/or (T317) D Step Motor Control circuit(s) for a short to voltage.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  3.
  3. CHECK THE (T314) A, (T315) B, (T316) C, AND (T317) D STEP MOTOR CONTROL CIRCUIT(S) FOR AN OPEN

    1. Turn the ignition off to the lock position.
    2. Measure separately the resistance of the (T314) A, (T315) B, (T316) C, and (T317) D Step Motor Control circuits between the TCM C1 harness connector and the Transmission Solenoid/Pressure Switch harness connector.

      Is the resistance above 5.0 Ohms for any of the Step Motor Control circuits?

      Yes 

      • Repair the (T314) A, (T315) B, (T316) C, and/or (T317) D Step Motor Control circuit(s) for an open.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  4.
  4. CHECK THE (T314) A, (T315) B, (T316) C, AND (T317) D STEP MOTOR CONTROL CIRCUIT(S) FOR A SHORT TO GROUND 
    Fig 3: Measuring Resistance Between Ground & A, B, C & D Step Motor Control Circuits

    1. Measure separately the resistance between ground and the (T314) A, (T315) B, (T316) C, and (T317) D Step Motor Control circuits.

      Is the resistance below 5.0 Ohms for any of the Step Motor Control circuits?

      Yes 

      • Repair the (T314) A, (T315) B, (T316) C, and/or (T317) D Step Motor Control circuit(s) for a short to ground.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  5.
  5. TRANSMISSION CONTROL MODULE 
    1. Replace the Transmission Control Module in accordance with the Service Information.
    2. Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      During the verification test did the DTC reset?

      Yes 

      • Replace Step Motor in accordance with the Service Information.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Test Complete.
  6. CHECK THE WIRING AND CONNECTORS 
    1. The conditions necessary to set this 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.

      Were there any problems found?

      Yes 

      No 

      • Test Complete.
