PINPOINT TEST F : The Windshield Wipers Operate In High Speed Only

  1. F1 CHECK THE FRONT WIPER COMMAND LOW SPEED (F_WIP_SLO_SW) PID

    • Ignition ON.
    • Using a scan tool, view SCCM PIDs.
    • While monitoring the SCCM PID F_WIP_SLO_SW, place the wiper/washer switch into the windshield wiper LOW speed position.

    Does the PID read ON when the wiper/washer switch is in the LOW speed position? 

    Yes  GO to  F2.
    No  For vehicles without the police package, INSTALL a new wiper/washer switch. REFER to Wiper and Washer Switch . If the concern is still present, INSTALL a new SCCM. REFER to STEERING COLUMN CONTROL MODULE (SCCM) . For vehicles with the police package, INSTALL a new multifunction switch. REFER to STEERING COLUMN MULTIFUNCTION SWITCH . If the concern is still present, INSTALL a new SCCM. REFER to STEERING COLUMN CONTROL MODULE (SCCM) .

  2. F2 CHECK THE WIPER PARK OPERATION

    • Place the windshield wiper switch in the HIGH position.
    • 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  F4.
    No  GO to  F3.

  3. F3 CHECK THE WINDSHIELD WIPER MOTOR LOGIC GROUND CIRCUIT FOR AN OPEN

    • Ignition OFF.
    • Disconnect: Windshield Wiper Motor.
    • Measure:
      Positive Lead Measurement / Action Negative Lead

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2414A-20
      GFD33596Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  F7.
    No  If the vehicle is not equipped with rain sensitive wipers, REPAIR the circuit. If the vehicle is equipped with rain sensitive wipers, GO to  F6.

  6. F6 ISOLATE THE RAIN SENSOR FOR THE SHORT TO GROUND

    • Disconnect: Rain Sensor.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2414A-20
      GFD33596Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance greater than 10, 000 ohms? 

    Yes  INSTALL a new rain sensor. REFER to Rain Sensor .
    No  REPAIR the circuit.

  7. F7 CHECK THE LIN CIRCUIT FOR A SHORT TO VOLTAGE

    • Ignition ON.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2414A-20
      GFD33595Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is any voltage present? 

    Yes  If the vehicle is equipped with rain sensitive wipers, GO to  F8. If the vehicle is not equipped with rain sensitive wipers, REPAIR the circuit.
    No  GO to  F9.

  8. F8 ISOLATE THE RAIN SENSOR FOR THE SHORT TO VOLTAGE

    • Ignition OFF.
    • Disconnect: Rain Sensor.
    • Ignition ON.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2414A-20
      GFD33595Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is any voltage present? 

    Yes  REPAIR the circuit.
    No  INSTALL a new rain sensor. REFER to Rain Sensor .

  9. F9 CHECK FOR CORRECT WINDSHIELD WIPER MOTOR OPERATION

    • Ignition OFF.
    • Inspect the windshield wiper motor electrical connector.
    • 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
    • Connect: Windshield Wiper Motor.
    • Connect: SCCM C2414A.
    • Connect: Rain Sensor (if equipped).
    • Make sure the electrical connectors seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no 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  F10.
    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.
