Pinpoint Test

  1. CHECK THE FRONT WIPER COMMAND LOW SPEED (F_WIP_SLO_SW) Parameter Identification (PID)
    1. Ignition ON.
    2. Using a scan tool, view Steering Column Control Module (SCCM) Parameter Identifications (PIDs).
    3. While monitoring the Steering Column Control Module (SCCM) Parameter Identification (PID) F_WIP_SLO_SW, place the wiper/washer switch into the windshield wiper LOW speed position.
      • Does the Parameter Identification (PID) read ON when the wiper/washer switch is in the LOW speed position? 
      • Yes:  If the vehicle is equipped with rain sensitive wipers, GO to 2  on page 2.

        If the vehicle is not equipped with rain sensitive wipers, GO to 3  on page 2.

      • No:  INSTALL a new wiper/washer switch. REFER to WIPER AND WASHER SWITCH . TEST the system for normal operation.

        If the concern is still present, GO to 9  on page 6.

  2. ISOLATE THE RAIN SENSOR
    1. Ignition OFF.
    2. Disconnect: Rain Sensor.
    3. Ignition ON.
    4. Operate the windshield wipers in low speed.
      • Do the windshield wipers operate in low speed? 
      • Yes:  INSTALL a new rain sensor. REFER to RAIN SENSOR .
      • No:  GO to 3  on page 2.
  3. CHECK THE WIPER PARK OPERATION
    1. Place the windshield wiper switch in the HIGH position.
    2. When the wiper blades are in the middle of the sweep pattern, place the windshield wiper switch in the OFF position.
      • Do the windshield wipers complete the sweep and then park correctly? 
      • Yes:  GO to 5  on page 3.
      • No:  GO to 4  on page 2.
  4. CHECK THE WINDSHIELD WIPER MOTOR LOGIC GROUND CIRCUIT FOR AN OPEN
    1. Ignition OFF.
    2. Disconnect: Windshield Wiper Motor.
    3. Measure:

      • Is the resistance less than 3 ohms? 
  5. CHECK THE Local Interconnect Network (LIN) CIRCUIT FOR AN OPEN
    1. Ignition OFF.
    2. Disconnect: Steering Column Control Module (SCCM) C2414A.
    3. Disconnect: Windshield Wiper Motor.
    4. Measure:
      Fig 2: Checking Local Interconnect Network (LIN) Circuit For Open
      G07429543Courtesy of FORD MOTOR CO.
      • Is the resistance less than 3 ohms? 
      • Yes:  GO to 6  on page 4.
      • No:  REPAIR the circuit.
  6. CHECK THE Local Interconnect Network (LIN) CIRCUIT FOR A SHORT TO GROUND
    1. Measure:
      Fig 3: Checking Local Interconnect Network (LIN) Circuit For Short To Ground
      G07429544Courtesy of FORD MOTOR CO.
      • Is the resistance greater than 10,000 ohms? 
      • Yes:  GO to 7  on page 5.
      • No:  REPAIR the circuit.
  7. CHECK THE Local Interconnect Network (LIN) CIRCUIT FOR A SHORT TO VOLTAGE
    1. Ignition ON.
    2. Measure:
      Fig 4: Checking Local Interconnect Network (LIN) Circuit For Short To Voltage
      G07429545Courtesy of FORD MOTOR CO.
      • Is the voltage greater than 11 volts? 
      • Yes:  REPAIR the circuit.
      • No:  GO to 8  on page 5.
  8. CHECK FOR CORRECT WINDSHIELD WIPER MOTOR OPERATION
    1. Ignition OFF.
    2. Inspect the windshield wiper motor electrical connector.
    3. Repair:
      • corrosion (install new connector or terminal - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    4. Connect: Windshield Wiper Motor.
    5. Connect: Steering Column Control Module (SCCM) C2414A.
    6. Connect: Rain Sensor (if equipped).
    7. Make sure the electrical connectors seat and latch correctly.
    8. Operate the system and determine if the concern is still present.
      • Is the concern still present? 
      • Yes:  CHECK On-Line Automotive Service Information System (OASIS) for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, DISCONTINUE this test and FOLLOW the Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new windshield wiper motor. REFER to WIPER MOTOR - WINDSHIELD .

        OPERATE the system and DETERMINE if the concern is still present. If the concern is still present, GO to 9  on page 6.

      • No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
  9. CHECK FOR CORRECT Steering Column Control Module (SCCM) OPERATION
    1. Ignition OFF.
    2. Disconnect and inspect all of the Steering Column Control Module (SCCM) electrical connectors.
    3. Repair:
      • corrosion (install new connector or terminal - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
