Pinpoint Test

  1. CHECK THE Steering Column Control Module (SCCM) VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
    1. Ignition OFF.
    2. Disconnect: Steering Column Control Module (SCCM) C2414A.
    3. Ignition ON.
    4. Measure:

      • Is the voltage greater than 11 volts? 
      1. Yes:  GO to 2  on page 2.
      2. No:  VERIFY the Body Control Module (BCM) fuse 23 (15A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short.
  2. CHECK THE Steering Column Control Module (SCCM) GROUND CIRCUITS FOR AN OPEN
    1. Ignition OFF.
    2. Measure:

      • Is the resistance less than 3 ohms? 
      1. Yes:  GO to 3  on page 3.
      2. No:  REPAIR the circuit.
  3. CHECK THE High Speed Controller Area Network (HS-CAN) CIRCUITS BETWEEN THE Steering Column Control Module (SCCM) AND THE Data Link Connector (DLC) FOR AN OPEN
    1. Measure:

      • Are the resistances less than 3 ohms? 
      1. Yes:  CONNECT the negative battery cable. GO to 4  on page 4.
      2. No:  REPAIR the circuit in question.
  4. CHECK FOR CORRECT Steering Column Control Module (SCCM) OPERATION
    1. Ignition OFF.
    2. Disconnect and inspect the Steering Column Control Module (SCCM) connectors.
    3. Repair:
      • corrosion (replace connector or terminals - clean module pins)
      • damaged or bent pins - replace terminals/pins
      • pushed-out pins - replace pins as necessary
    4. Reconnect the Steering Column Control Module (SCCM) connectors. Make sure they seat and latch correctly.
    5. Operate the system and verify 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. Concern may have been caused by a loose or corroded connector.
