Pinpoint Test C: Torque Converter Clutch (TCC) Solenoid

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Refer to the Transaxle Vehicle Harness Connector illustration preceding these pinpoint tests.
  1. C1 CHECK FOR BATTERY VOLTAGE AT THE TRANSAXLE CONNECTOR 
    CAUTION: Do not pry on the connector. This will damage the connector and may result in a transaxle concern. Press button and pull up on the transaxle vehicle harness connector.
    • Disconnect: Transaxle Connector C199
    • Inspect the transaxle vehicle harness connector for damage. Make sure the pins are fully engaged and in good condition before proceeding.
    • Key in ON position.
    • Measure the voltage at transaxle connector C199-3, circuit CBB24 (VT/GN).

    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  C4.
    2. NO  : Go to  C2.
  2. C2 CHECK BATTERY CONTROL MODULE (BCM) FUSE 24 (10A) 
    • Check fuse: Battery Control Module (BCM) Fuse 24 (10A)
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  C3.
    2. NO  : REPAIR circuit CBB24 (VT/GN) or circuit CBB28 (GY/VT) for a short to ground. CONNECT all electrical connectors. TEST the system for normal operation.
  3. C3 CHECK THE SOLENOID POWER SUPPLY CIRCUIT FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: BCM Fuse 24 (10A)
    • Measure the resistance between the output side of BCM fuse 24 (10A) or circuit CBB28 (GY/VT) and transaxle connector C199-3, circuit CBB24 (VT/GN).
      • Fig 2: Measuring Resistance

    • Is the resistance less than 5 ohms? 
    1. YES  : Circuit CBB24 (VT/GN) or circuit CBB28 (GY/VT) has an intermittent open circuit. REPEAT this test step while wiggling the wiring harness. INSPECT the vehicle wiring harness for damage and repair as necessary.
    2. NO  : REPAIR circuit CBB24 (VT/GN) or circuit CBB28 (GY/VT) for an open. CONNECT all electrical connectors. TEST the system for normal operation.
  4. C4 CHECK SOLENOID CONTROL CIRCUIT FOR A SHORT TO POWER AND GROUND 
    • Disconnect: PCM Connector C175T
    • Inspect the PCM connector for damage. Make sure the pins are fully engaged and in good condition before proceeding.
    • Measure the resistance between PCM connector C175T-46, circuit CE418 (BU/OG) and ground and transaxle connector C199-3, circuit CBB24 (VT/GN).
      • Fig 3: Measuring Resistance

    • Is each resistance greater than 10,000 ohms? 
    1. YES  : Go to  C5.
    2. NO  : REPAIR circuit CE418 (BU/OG) for a short. CONNECT all components. TEST the system for normal operation.
  5. C5 CHECK THE SOLENOID CONTROL CIRCUIT FOR AN OPEN 
    • Measure the resistance between PCM connector C175T-46, circuit CE418 (BU/OG) and transaxle connector C199-4, circuit CE418 (BU/OG).
      • Fig 4: Checking Circuit For Open
      GF0024717Courtesy of FORD MOTOR CO.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  C6.
    2. NO  : REPAIR circuit CE418 (BU/OG) for an open. CONNECT all components. TEST the system for normal operation.
  6. C6 CHECK THE RESISTANCE OF THE SOLENOID FIELD CIRCUIT 
    • Measure the resistance between transaxle connector C199 pin 3, component side and pin 4, component side.
      • Fig 5: Measuring Resistance
      GF0042344Courtesy of FORD MOTOR CO.
    • Is the resistance between 12.5 and 19.0 ohms? 
    1. YES  : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS - 2.3L article or ELECTRONIC ENGINE CONTROLS - 3.0L (4V) article. RECONNECT all components. TEST the system for normal operation. If symptoms are still present, REFER to Diagnosis By Symptom .
    2. NO  : INSTALL a new main control assembly. REFER toMain Control Valve Body . CONNECT all components. TEST the system for normal operation.
