Pinpoint Test

  1. CHECK THE CRUISE CONTROL SWITCH
    1. Ignition ON.
    2. Using a scan tool, view the Steering Column Control Module (SCCM) Parameter Identifications (PIDs).
    3. Press each cruise control switch while monitoring the cruise control switch Parameter Identification (PID) (SCCS).
      CRUISE CONTROL SWITCH REFERENCE CHART

      Cruise Control Switch SCCS Parameter Identification (PID) Value
      - None pressed
      RES/CNCL RESUME/CANCEL
      ON/OFF On/Off
      SET (pressed up) SET/+
      SET (pressed down) SET/-
      GAP (pressed up) GAP
      GAP (pressed down) GAP+
      • Does the Parameter Identification (PID) value agree with the switch position? 
      1. Yes:  GO to 5  on page 5.
      2. No:  If only one switch value does not display the correct Parameter Identification (PID) value, INSTALL a new Left Hand (LH) steering wheel switch. REFER to STEERING WHEEL SWITCH .

        Otherwise, GO to 2  on page 2.

  2. CHECK FOR VOLTAGE TO THE CRUISE CONTROL SWITCHES
    1. Ignition OFF.
    2. Remove the driver air bag module. REFER to DRIVER AIR BAG MODULE .
    3. Disconnect Left Hand (LH) Steering Wheel Controls.
    4. Ignition ON.
    5. Measure:

      • Is the voltage approximately 5 volts? 
      1. Yes:  INSTALL a new Left Hand (LH) steering wheel switch. REFER to STEERING WHEEL SWITCH .
      2. No:  GO to 3  on page 3.
  3. CHECK FOR VOLTAGE TO THE CLOCKSPRING
    1. Ignition OFF.
    2. Disconnect Clockspring C218B.
    3. Ignition ON.
    4. Measure:
      Fig 2: Checking Clockspring Voltage

      • Is the voltage approximately 5 volts? 
      1. Yes:  INSTALL a new steering wheel. REFER to STEERING WHEEL .
      2. No:  GO to 4  on page 4.
  4. CHECK FOR VOLTAGE AT THE Steering Column Control Module (SCCM)
    1. Ignition OFF.
    2. Remove the clockspring. REFER to CLOCKSPRING .
    3. Ignition ON.
    4. Measure:
      Fig 3: Checking For Voltage At Steering Column Control Module (SCCM)
      G07432700Courtesy of FORD MOTOR CO.
      • Is the voltage approximately 5 volts? 
      1. Yes:  INSTALL a new clockspring. REFER to CLOCKSPRING .
      2. No:  GO to 5  on page 5.
  5. CHECK FOR CORRECT Steering Column Control Module (SCCM) OPERATION
    1. Disconnect all the Steering Column Control Module (SCCM) connectors.
    2. Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    3. Reconnect all the Steering Column Control Module (SCCM) connectors and make sure they are seated correctly.
    4. Connect all disconnected connectors.
    5. Install the driver air bag module. REFER to DRIVER AIR BAG MODULE .
    6. Operate the system and determine if the concern is still present.
      • Is the concern still present? 
      1. 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 Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new Steering Column Control Module (SCCM). REFER to STEERING COLUMN CONTROL MODULE (SCCM) .
      2. No:  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
