Pinpoint Test E : The Ignition Key Can Be Turned To The Off Position When The Selector Lever Is Not In Park

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. Shift Interlock for schematic and connector information.

    Normal Operation and Fault Conditions 

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

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM B1472:12 Ignition Key Removal Inhibit: Circuit Short To Battery Sets when the BCM detects a short to voltage from the key removal inhibit solenoid control circuit.
    BCM B1472:14 Ignition Key Removal Inhibit: Circuit Short To Ground Or Open Sets when the BCM detects an open from the key removal inhibit solenoid control circuit.

    Possible Sources 

    • Wiring, terminals or connectors
    • Ignition switch
    • Selector lever assembly (floor shifter)
    • Brake shift interlock actuator (column shifter)
    • 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. NOTE: The following Pinpoint Test uses a test lamp to simulate normal circuit loads. Use only a Rotunda Test Lamp (SGT27000) or 250- 300mA incandescent bulb test lamp. To avoid connector terminal damage, use the Rotunda Flex Probe kit for the test lamp probe connection to the vehicle. Do not use the test lamp probe directly on any connector.
  4. E1 CHECK THE KEY INHIBIT SOLENOID CIRCUIT FOR GROUND

    • Ignition OFF.

    • Disconnect Ignition Switch C250.

    • Set the park brake.

    • Select NEUTRAL.

    • Connect:
      Positive Lead Measurement / Action Negative Lead
      Refer to C250-4

      Refer to C250-3

    Is the test lamp illuminated? 

    Yes  INSTALL a new ignition switch. REFER to: Ignition Switch .
    No  GO to  E2
  5. E2 CHECK THE KEY INHIBIT SOLENOID CIRCUIT FOR AN OPEN

    • Disconnect Selector Lever Assembly C3233.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      Refer to C250-3
      GFD324698Courtesy of FORD MOTOR COMPANY
      Refer to C3233-2

    Is the resistance less than 3 ohms? 

    Yes  GO to  E3
    No  REPAIR the circuit.
  6. E3 BYPASS THE SELECTOR LEVER

    • Connect:
      Positive Lead Measurement / Action Negative Lead
      Refer to C250-4
      GFD324701Courtesy of FORD MOTOR COMPANY
      Refer to C250-3

    • Connect:
      Lead 1 Measurement / Action Lead 2
      Refer to C3233-2
      GFD324700Courtesy of FORD MOTOR COMPANY
      Refer to C3233-12

    • Remove the fused jumper wire.

    Does the test lamp illuminate with the fused jumper wire connected? 

    Yes  INSTALL a new selector lever assembly. REFER to: Selector Lever .
    No  GO to  E4
  7. E4 CHECK THE KEY INHIBIT SOLENOID CIRCUIT FOR A SHORT TO VOLTAGE

    • Connect:
      Positive Lead Measurement / Action Negative Lead
      Refer to C3233-3
      GFD324701Courtesy of FORD MOTOR COMPANY
      Ground

    Does the test lamp illuminate? 

    Yes  REPAIR the circuit.
    No  GO to  E5
  8. E5 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 On-Line Automotive Service Information System (OASIS) for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, DISCONTINUE this test and FOLLOW Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) 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.
