      Yes 

      • Go To  6.

      No 

      • Repair Pressure Control Solenoid 2 (SL2) Signal circuit for an open or high resistance.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST  .
  6. CHECK PRESSURE CONTROL SOLENOID 2 (SL2) SIGNAL RETURN CIRCUIT FOR AN OPEN OR HIGH RESISTANCE 
    1. Disconnect the transmission pass through harness connector.
    2. Measure the resistance of Pressure Control Solenoid 2 (SL2) Signal Return circuit between the Transmission Assembly harness connector and the TCM harness connector.

      Is the resistance below 3.0 Ohms?

      Yes 

      • Replace the Pressure Control Solenoid (SL2) and Internal Transmission Harness in accordance with the Service Information.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST  .

      No 

      • Repair Pressure Control Solenoid 2 (SL2) Signal Return circuit for an open or high resistance.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST  .
  7. CHECK THE PRESSURE CONTROL SOLENOID (SL2) SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    1. Connect the Transmission Harness Pass Through Connector.
    2. Check for continuity between ground and Pressure Control Solenoid 2 (SL2) Signal circuit at the TCM harness connector.

      Is there continuity between ground and Pressure Control Solenoid 2 (SL2) Signal circuit?

      Yes 

      • Repair Pressure Control Solenoid 2 (SL2) Signal circuit for a short to ground.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST  .

      No 

      • Go To  8.
  8. CHECK PRESSURE CONTROL SOLENOID 2 (SL2) SIGNAL CIRCUIT FOR A SHORT TO ANOTHER CIRCUIT 
    1. Connect the transmission pass through harness connector.
    2. Check for continuity between circuit and all other circuits in the TCM harness connector.

      Is there continuity between any other circuits and Pressure Control Solenoid 2 (SL2) Signal circuit?

      Yes 

      • Repair Pressure Control Solenoid 2 (SL2) Signal circuit for a short to another circuit.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST  .

      No 

      • Go To  9.
  9. CHECK PRESSURE CONTROL SOLENOID 2 (SL2) SIGNAL RETURN CIRCUIT FOR A SHORT TO GROUND 
    1. Connect the transmission pass through harness connector.
    2. Check for continuity between ground and Pressure Control Solenoid 2 (SL2) Signal Return circuit at the TCM harness connector.

      Is there continuity between ground and Pressure Control Solenoid 2 (SL2) Signal Return circuit?

      Yes

      No 

  11. CHECK FOR AN INTERMITTENT CONDITION 
    NOTE:

    The conditions necessary to set the DTC are not present at this time. The code set because of an intermittent condition. Try to determine the cause in this step.

    Turn the ignition off.

    1. Disconnect all TCM harness connectors.
    2. Disconnect all related in-line harness connections (if equipped).
    3. Disconnect the related component harness connectors.
    4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
      • Proper connector installation.
      • Damaged connector locks.
      • Corrosion.
      • Other signs of water intrusion.
      • Weather seal damage (if equipped).
      • Bent terminals.
      • Terminals that have been pushed back into the connector cavity.
      • Perform a terminal drag test on each connector terminal to verify proper terminal tension.
    5. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
    6. Wiggle the wires while checking for shorted and open circuits.
