Pinpoint Test

  1. CHECK THE CRUISE CONTROL SWITCH
    1. Ignition ON.
    2. Using a scan tool, view the SCCM PIDs  .
    3. Press each cruise control switch while monitoring the cruise control switch PID (SCCS).
      Cruise Control Switch SCCS 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 PID value agree with the switch position? 

    1. Yes: GO to  5.
    2. No: If only one switch value does not display the correct PID value, INSTALL a new LH steering wheel switch. REFER to STEERING WHEEL SWITCH .

      Otherwise, GO to 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 LH Steering Wheel Controls.
    4. Ignition ON.
    5. Measure:

    Is the voltage approximately 5 volts? 

    1. Yes: INSTALL a new LH steering wheel switch. REFER to STEERING WHEEL SWITCH .
    2. No: GO to 3  .
  3. CHECK FOR VOLTAGE TO THE CLOCKSPRING
    1. Ignition OFF.
    2. Disconnect Clockspring C218B.
    3. Ignition ON.

    2. No: GO to 4  .
  4. CHECK FOR VOLTAGE AT THE SCCM
    1. Ignition OFF.
    2. Remove the clockspring. REFER to CLOCKSPRING .
    3. Ignition ON.

    Is the voltage approximately 5 volts? 

    1. Yes: INSTALL a new clockspring. REFER to CLOCKSPRING .
    2. No: GO to 5  .
  5. CHECK FOR CORRECT SCCM OPERATION
    1. Disconnect all the 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 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 OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs  address this concern, INSTALL a new 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.
