Pinpoint Test A: Shift And Torque Converter Clutch Solenoids

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Read and record all DTCs. All Digital TR Sensor and VSS DTCs must be repaired before entering Output State Control (OSC).
NOTE: Refer to the Transmission Internal Harness illustration preceding these pinpoint tests.
NOTE: Refer to the transmission vehicle harness connector illustration preceding these pinpoint tests.

    • Select TCC for Torque Converter Clutch Solenoid. Follow procedures of TCC in Drive Mode as listed.
    • Does the transmission upshift and downshift or torque converter engage/disengage when commanded? 
    • Yes  : CLEAR all DTCs. ROAD TEST to verify if concern is still present. If concern is still present, REFER to DIAGNOSIS BY SYMPTOM  to diagnose shift or torque converter concern.
    • No  : GO to A5.
  5. A5 CHECK FOR BATTERY VOLTAGE 
    • Remove transmission fluid pan.
    • Visually inspect the lead frame and connectors for damage.
    • Key in ON position.
    • Measure the voltage with the positive lead to VPWR solenoid pin and negative lead to a good ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to A6.
    • No  : CHECK for open or short circuit in harness or solenoid.
  6. A6 ELECTRICAL SIGNAL CHECK 
    • Measure the voltage with the positive lead connected to VPWR solenoid pin and the negative lead to the signal pin of the appropriate solenoid.

  13. Enter the following diagnostic mode on the scan tool: Select Parameter TCC.
  14. Select "ON".
  15. Press "SEND".
  16. Turn the solenoid ON and OFF, while monitoring the voltage, solenoid state on the diagnostic tool (ON and OFF) and listen for the solenoid to activate (click).
  17. Select "OFF", press "SEND".
  18. Does the voltage and solenoid state change? 
    • Yes  : GO to A7.
    • No  : CHECK for open or short circuit in harness, solenoid or a PCM concern.
