Pinpoint Test A: Shift And Torque Converter Clutch Solenoids

WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Refer to the TRANSMISSION VEHICLE HARNESS  Connector illustration preceding these pinpoint tests.
NOTE: Refer to the Internal Harness Diagram illustration preceding these pinpoint tests.
NOTE: Read and record all DTCs. All Digital TR Sensor and VSS DTCs must be repaired before entering Output State Control (OSC).
  1. A1 ELECTRONIC DIAGNOSTICS 
    • Key in OFF position.
    • Select PARK.
    • Check to make sure the transmission harness connector is fully seated, terminals are fully engaged in connector and in good condition before proceeding.
    • Connect the diagnostic tool.
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Diagnostic Data Link.

    • Enter the following diagnostic mode on the diagnostic tool: Trans-Bench Mode.
    • Does vehicle enter Trans-Bench Mode? 

    Yes 

    REMAIN in Trans-Bench Mode. GO to A2.

    No 

    REPEAT procedure to enter Trans-Bench Mode. If vehicle did not enter Trans-Bench Mode, REFER to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE for diagnosis of PCM or NGS.

  2. A2 WIGGLE TEST 
    • Remain in Trans-Bench Mode.
    • Select PIDs to be monitored.

    • Select "ON" to turn suspect solenoid on.
    • Press "SEND".
    • Wiggle all wiring and connectors to the transmission.
    • Monitor the solenoid state for changes.
    • Select "OFF" to turn solenoid off.
    • Press "SEND".
    • Does the suspect solenoid(s) fault state change? 

    Yes 

    REPAIR the circuit. TEST the system for normal operation.

    No 

    GO to A3.

  3. A3 SOLENOID FUNCTIONAL CHECK 
    • Monitor each solenoid state.
    • Turn each solenoid ON and OFF.
    • Does the solenoid turn ON and OFF when commanded and can solenoid activation be heard? 

    Yes 

    GO to A4.

    No 

    GO to  A5.

  4. A4 OSC TRANS-DRIVE MODE (GEAR OR TCC) 
    • Carry out OSC Trans-Drive Mode.
    • Select GEAR for shift solenoids or follow procedures for GEAR as listed.
    • 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 
    • Disconnect: Transmission Vehicle Harness Connector.
    • Visually inspect all wires and connectors for damage.
    • Key in ON position.
    • Measure the voltage on pin 3 harness side and ground.

    • Enter the following diagnostic mode on the diagnostic tool: Trans-Bench Mode.
    • Select Parameter SSA, SSB, SSC, SSD or TCC.
    • Select "ON".
    • Press "SEND".
    • Measure the voltage while cycling the solenoids ON and OFF.
    • Select "OFF", press "SEND".
    • Does the voltage change? 

    Yes 

    GO to A7.

    No 

    REPAIR the circuit. TEST the system for normal operation.

  7. A7 CHECK SOLENOID RESISTANCE AT SOLENOID 
    • Measure the resistance between pin 3 and pins 5, 6, 14, 15, and 16 solenoid side.
