Pinpoint Test A: Shift And Torque Converter Clutch Solenoids

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Refer to Figure 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 scan tool.
    • Key in ON position.
    • Enter the following diagnostic mode on the scan tool: Diagnostic Data Link.
    • Enter the following diagnostic mode on the scan tool: PCM.
    • Enter the following diagnostic mode on the scan tool: Active Command Modes.
    • Enter the following diagnostic mode on the scan tool: Output State Control (OSC).
    • Enter the following diagnostic mode on the scan 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, See INTRODUCTION - GASOLINE article for diagnosis of PCM or NGS.
  2. A2 WIGGLE TEST 
    • Remain in Trans-Bench Mode.
    • Select PIDs to be monitored.
      PID Command PID Actual
      SSA SSA
      SSB SSB
      SSC SSC
      SSD SSD
      TCC TCC
    • Select "ON" to turn suspect solenoid(s) on.
    • Press "SEND."
    • Wiggle all wiring and connectors to the transmission. Monitor the solenoid state for changes.
    • Select "OFF" to turn solenoid(s) off.
    • Press "SEND."
    • Repeat steps for each solenoid.
    • Does the suspect solenoid(s) 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 in this article.
    • Select TCC for torque converter clutch solenoid. Follow procedures of TCC in Drive Mode as listed in this article.
    • 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.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to  A6
    • No  : REPAIR the circuit. TEST for normal operation.
  6. A6 ELECTRICAL SIGNAL CHECK 
    • Leave positive lead connected to pin 3 and connect negative lead to pin 5, 6, 14, 15 and 16.

    • Enter the following diagnostic mode on the scan 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 resistance between pin 3 and pin 5, 6, 14, 15 and 16 solenoid side.
      Solenoid Resistance (ohms)
      SSA 16-45
      SSB 16-45
      SSC 16-45
      SSD 16-45
      TCC 9-16
