Pinpoint Test H: The Traction Control System Cannot Be Disabled

CAUTION: Use the correct probe adapter(s) when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. H1 CHECK CIRCUIT 91-CF54 (BK/WH) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: Traction Control Switch C2267

    • Measure the resistance between traction control switch C2267-1, circuit 91-CF54 (BK/WH), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  H2.
    2. NO  : REPAIR circuit 91-CF54 (BK/WH). CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
  2. H2 CHECK THE TRACTION CONTROL SWITCH 
      Fig 2: Measuring Resistance

    • Measure the resistance between traction control switch C2267, pin 1 and pin 2 (component side) while pressing the traction control switch.
    • Is the resistance less than 5 ohms with the traction control switch pressed and greater than 10,000 ohms with the traction control switch released? 
    1. YES  : Go to  H3.
    2. NO  : INSTALL a new traction control switch. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
  3. H3 CHECK CIRCUIT 91S-CF54 (BK/WH) FOR AN OPEN 
    • Disconnect: ABS Module C135
      • Fig 3: Measuring Resistance
      GF0039663Courtesy of FORD MOTOR CO.
    • Measure the resistance between ABS module C135-38, circuit 91S-CF54 (BK/WH), harness side and traction control switch C2267-2, circuit 91S-CF54 (BK/WH), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  H4.
    2. NO  : REPAIR circuit 91S-CF54 (BK/WH). CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
  4. H4 CHECK FOR CORRECT ABS MODULE OPERATION 
    • Disconnect all ABS connectors.
    • Check for:
      • corrosion.
      • pushed-out pins.
      • spread terminals.
    • Connect all ABS connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. YES  : INSTALL a new ABS module. REFER to Anti-Lock Brake System (ABS) Module . TEST the system for normal operation.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
