Pinpoint Test

  1. CHECK FOR SCCM DTCs 
    1. Ignition ON.
    2. Using a scan tool, perform SCCM self-test.
    3. Clear the SCCM DTCs  and repeat the self-test.

    Is DTC B119D:16 still present? 

    1. Yes:  GO to .
    2. No  : The system is operating normally at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.
  2. CHECK FOR CHARGING SYSTEM DTCs  IN THE PCM
    1. Using a scan tool, perform PCM self-test.
    2. Record all CMDTCs  from the PCM.

    Are any charging system DTCs present in the PCM? 

    1. Yes:  REFER to DTC CHART: POWERTRAIN CONTROL MODULE (PCM) to diagnose the charging system DTCs  .
    2. No  : GO to .
  3. CHECK THE BATTERY CONDITION AND STATE OF CHARGE
    1. Ignition OFF.
    2. Carry out the Battery Condition Test. REFER to DIAGNOSTIC ROUTINE A : Battery Condition Test.

    Is the battery OK? 

    1. Yes:  GO to .
    2. No  : CORRECT the battery condition.
  4. CHECK THE SCCM VOLTAGE SUPPLY
    1. Measure and record battery voltage.
    2. Disconnect: SCCM C2414A.
    3. Disconnect: SCCM C2414B.
    4. Measure:
      SCCM Ground
      G08028379
      G08028380
      C2414A Ground
      Pin Circuit Measurement / Action Pin Circuit
      10 SBP23 (WH/RD)
      G08028381
      - Ground
    5. Measure:
      SCCM Ground
      G08028382
      G08028383
      C2414B Ground
      Pin Circuit Measurement / Action Pin Circuit
      8 SBP24 (VT/RD)
      G08028384
      - Ground

    Are the voltages within 0.2 volt of the recorded battery voltage? 

    1. Yes:  GO to .
    2. No  : VERIFY BCM fuses 23 (15A) and 24 (15A) are OK. If OK, REPAIR the affected circuit(s). If not OK, REFER to the appropriate wiring diagrams to identify the possible causes of the circuit short. REFER to OEM FUSE AND RELAY INFORMATION and OEM WIRING DIAGRAMS .
  5. CHECK THE SCCM GROUND CIRCUIT
    1. Disconnect the battery negative cable. REFER to BATTERY DISCONNECT .
    2. Measure:
      SCCM Ground
      G08028385
      G08028386
      C2414A Ground
      Pin Circuit Measurement / Action Pin Circuit
      13 GD214 (BK/BU)
      G08028387
      - Ground
    3. Measure:
      SCCM Ground
      G08028388
      G08028389
      C2414B Ground
      Pin Circuit Measurement / Action Pin Circuit
      5 GD214 (BK/BU)
      G08028390
      - Ground

    Are the resistances less than 3 ohms? 

    1. Yes:  CONNECT the battery negative cable. GO to .
    2. No  : REPAIR the affected circuit(s). CONNECT the battery negative cable.
  6. CHECK FOR CORRECT SCCM OPERATION
    1. Disconnect and inspect all 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 the SCCM connectors and all previously disconnected exterior system connectors. Make sure they seat and latch correctly.
    4. 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.
