WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. J1 PERFORM INSPECTION AND VERIFICATION 

    Was an obvious cause for an observed or reported concern found? 

    • Yes  : CORRECT the cause as necessary.
    • No  : GO to J2  .
  2. J2 CHECK BATTERY AND GENERATOR CONNECTIONS 
    • Inspect the battery and generator for loose or corroded connections.
    • Inspect the battery and engine for loose or corroded ground connections.
    • Inspect the generator for loose or corroded connections.
    • Inspect In-line connector C192  for:
      • 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

    Were any concerns present? 

    • Yes  : CORRECT the cause as necessary.
    • No  : GO to  J4.
  3. J3 VERIFY THE CUSTOMER CONCERN 
    • Verify the customer concern by operating the charging system.

    Did the customer indicate battery saver message only appeared in the centerstack with the engine running? 

    • Yes  : REFER to Refer to the appropriate article for the procedure.
    • No  : GO to J4  .
  4. J4 VERIFY THE NETWORK 
    • Ignition ON.
    • Using a diagnostic scan tool, perform the Network Test.

    Did the APIM  , BCM  , and PCM pass the Network Test? 

  5. J5 PERFORM PCM SELF TEST 
    • Ignition ON.
    • Using a diagnostic scan tool, perform the PCM  self-test.

    Were any battery or charging system related Diagnostic Trouble Codes (DTCs) retrieved? 

  6. J6 RETRIEVE ALL CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCs) 
    • Ignition ON.
    • Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

    Were any battery or charging system related Diagnostic Trouble Codes (DTCs) retrieved? 

    • Yes  : For BCM  Diagnostic Trouble Codes (DTCs) refer to Diagnostic Trouble Code (DTC) Chart . For APIM  or ACM  Diagnostic Trouble Codes (DTCs), Refer to the appropriate article for the procedure.

      For other battery or charging system related Diagnostic Trouble Codes (DTCs), MULTIFUNCTION ELECTRONIC MODULES DTC Chart.

    • No  : GO to J7  .
  7. J7 CHECK BCM BAT_ST_CHRG PID 
    • Ignition ON.
    • Using a diagnostic scan tool, view the BCM  Parameter Identifications (PIDs).
    • Monitor the BCM  BAT_ST_CHRG PID  .

    Does the PID indicate 50% or more? 

    • Yes  : GO to  J9.
    • No  : GO to J8  .
  8. J8 RELEARN BATTERY STATE OF CHARGE 
    NOTE: The battery state of charge is too low and needs to be relearned. Refer to DESCRIPTION AND OPERATION  in this article for more information on battery state of charge.
    • Remove all accessories from the lighter, all power outlets and, if equipped, the DC/AC inverter.
    • NOTE: The key should not be left in the vehicle but should be left in a secure location away from the vehicle such as a lock box.

      Allow the vehicle to sit undisturbed for at least 8 hours.

    • Ignition ON.
    • Using a diagnostic scan tool, view the BCM  Parameter Identifications (PIDs).
    • Monitor the BCM  BAT_ST_CHRG PID  .

    Does the PID indicate 50% or more? 

    • Yes  : The concern may have been caused by too low of a battery state of charge. REVIEW Energy Management operation with customer and return vehicle to customer.
    • No  : GO to J9  .
  9. J9 VERIFY IN-LINE CONNECTOR 
    • Inspect in-line connector C192  for secure connection.
    • Disconnect: In-line connector C192  .
    • Inspect for:
      • 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

    Were any concerns present? 

    • Yes  : CORRECT the cause as necessary.
    • No  : GO to J10  .
  10. J10 CHECK FOR CORRECT BCM OPERATION 
    • Ignition OFF.
    • Disconnect and inspect all BCM  connectors.
    • 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
    • Reconnect all connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    • Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW the TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM  . REFER to BODY CONTROL MODULE (BCM) CLEAR all Diagnostic Trouble Codes (DTCs) in all modules.
    • 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.
