Pinpoint Test

  1. RECHECK THE FLM DTCs 
    1. Ignition ON.
    2. Using a scan tool, clear the DTCs  and repeat the FLM on-demand self-test.

    Is DTC B11D9:16 still present? 

    • Yes: GO to 2  .
    • No: The system is operating normally at this time. The DTC may have been set due to a previous low battery voltage condition.
  2. CHECK FOR CHARGING SYSTEM DTCs  IN THE PCM
    1. Enter the following diagnostic mode on the scan tool: PCM Self-Test.
    2. Using a scan tool, perform the PCM KOEO self-test.
    3. Using a scan tool, retrieve the continuous memory DTCs  from the PCM.

    Are any charging system DTCs set in the PCM? 

  3. CHECK THE BATTERY CONDITION AND STATE OF CHARGE
    1. Ignition OFF.
    2. Check the battery condition and verify the battery is fully charged. REFER to DIAGNOSTIC ROUTINE A : Battery Condition Test.

    Is the battery OK and fully charged? 

  4. CHECK THE FLM VOLTAGE PID
    1. Ignition ON.
    2. Measure and record the voltage at the battery.
    3. Using a scan tool, view FLM PIDs  .
    4. Using a scan tool, monitor the FLM VBAT_INPUT PID.

    Is the voltage within 0.2 volt of the recorded battery voltage? 

    • Yes: GO to  7.
    • No: GO to 5  .
  5. CHECK THE FLM VOLTAGE SUPPLY CIRCUIT FOR HIGH RESISTANCE
    1. Ignition OFF.
    2. Disconnect: FLM.
    3. Ignition ON.
    4. Measure:
      FLM Ground
      G08036708
      G08036709
      C205 Ground
      Pin Circuit Measurement / Action Pin Circuit
      1 SBP23 (WH/RD)
      G08036710
      		 - Ground

    Is the voltage within 0.2 volt of the recorded battery voltage? 

    • Yes: GO to 6  .
    • No: REPAIR the circuit.
  6. CHECK THE FLM GROUND CIRCUIT FOR HIGH RESISTANCE
    1. Ignition OFF.
    2. Measure:
      FLM Ground
      G08036711
      G08036712
      C205 Ground
      Pin Circuit Measurement / Action Pin Circuit
      7 GD214 (BK/BU)
      G08036713
      		 - Ground

    Is the resistance less than 3 ohms? 

    • Yes: GO to 7  .
    • No: REPAIR the circuit.
  7. CHECK FOR CORRECT FLM OPERATION
    1. Disconnect and inspect all BCM 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 BCM 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? 

    • 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 FLM. REFER to Front Lighting Control Module (FLM) .
    • 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.
