Pinpoint Test A: No Power In All Ignition Switch Positions - Conventional Ignition Switch

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to Wiring Diagrams Power Distribution for schematic and connector information.

    Normal Operation and Fault Conditions 

    REFER to: Steering Wheel and Column Electrical Components - System Operation and Component Description .

    Possible Sources 

    • Fuse
    • Wiring, terminals or connectors
    • Ignition switch
    • BCM

    Visual Inspection and Pre-checks 

    • Inspect the battery and battery cables
    • Inspect the BCM fuse 20 (5A)

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

  3. A1 CHECK THE VEHICLE BATTERY

    • Carry out the Battery Condition Test. REFER to: Battery .

    Is the battery OK? 

    Yes  GO to  A2
    No  CORRECT the battery condition.

  4. A2 CHECK FOR VOLTAGE TO THE IGNITION SWITCH

    • Ignition OFF.

    • Disconnect Ignition Switch C250.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C250-4

      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  INSTALL a new ignition switch. REFER to: Ignition Switch .
    No  VERIFY the BCM fuse 20 (5A) is OK. If OK, GO to  A3
    If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible cause of the circuit short.

  5. A3 CHECK THE IGNITION SWITCH VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

    • Disconnect BCM C2280A.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C250-4
      GFD552276Courtesy of FORD MOTOR COMPANY
      		 C2280A-12

    Is the resistance less than 3 ohms? 

    Yes  GO to  A4
    No  REPAIR the circuit.

  6. A4 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • 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 the BCM connectors and all other previously disconnected 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 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, INSTALL a new BCM REFER to: Body Control Module (BCM) .
    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.
