Pinpoint Test J : All Door Locks Are Inoperative

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to REMOTE KEYLESS ENTRY AND ALARM for schematic and connector information.

    Normal Operation and Fault Conditions 

    REFER to: Handles, Locks, Latches and Entry Systems - System Operation and Component Description .

    Possible Sources 

    • Wiring, terminals or connectors
    • BCM

  2. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

  3. J1 CHECK FOR BCM (BODY CONTROL MODULE), DDM (DRIVER DOOR MODULE) AND PDM (PASSENGER DOOR MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the BCM self-test. (Vehicles without  passenger door one-touch windows).

    • Using a diagnostic scan tool, carry out the DDM self-test. (Vehicles with  passenger door one-touch windows).

    • Using a diagnostic scan tool, carry out the PDM self-test. (Vehicles with  passenger door one-touch windows).

    Are any Diagnostic Trouble Codes (DTCs) present? 

    Yes  REFER to the DTC Chart: BCM , the DTC Chart: DDM (With Passenger Door One-Touch Windows) , or the DTC Chart: PDM (With Passenger Door One-Touch Windows) .
    No  GO to  J2

  4. J2 VERIFY THE OPERATION OF THE DOOR LOCK CONTROL SWITCHES

    • Press the lock and unlock buttons on the door lock control switches while observing the door lock operation.

    Does any door lock operate? 

    Yes  GO to  J3
    No  GO to  J4

  5. J3 CHECK IF THE LOCKS OPERATE IN ONLY ONE DIRECTION

    • Press the lock and unlock buttons on the door lock control switches while observing the door lock operation.

    Are all the door locks inoperative from both switch positions (lock and unlock) of the door lock control switches? 

    Yes  GO to Pinpoint Test M 
    No  GO to Pinpoint Test L 

  6. J4 CHECK THE BCM (BODY CONTROL MODULE) DOOR LOCK GROUND CIRCUIT FOR AN OPEN

    • Ignition OFF.

    • Disconnect: BCM C2280F.

    • Measure

      		 Ground

    Is the resistance less than 3 ohms? 

    Yes  GO to  J5
    No  REPAIR the circuit.

  7. J5 CHECK THE ALL DOOR LOCK CIRCUITS FOR AN OPEN

    • Disconnect: LHF Door Lock Actuator C525.

      Positive Lead Measurement / Action Negative Lead
      C2280F-1
      GFD329130Courtesy of FORD MOTOR COMPANY
      		 C525-7

    Is the resistance less than 3 ohms? 

    Yes  GO to  J6
    No  REPAIR the circuit.

  8. J6 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Disconnect and inspect all the BCM connectors.

    • Repair:

      • corrosion (install new connectors or terminals - clean module pins)
      • damaged or bent pins - install new terminals pins
      • pushed-out pins - install new pins as necessary

    • Reconnect the BCM connectors and 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 service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, Refer to BCM GUIDED ROUTINE TESTING
    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.
