Pinpoint Test U : B1202:12, B1202:14

  1. Normal Operation and Fault Conditions 

    REFER to: Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - System Operation and Component Description .

    The PAD indicator is part of the overhead console and cannot be serviced separately.

    The RCM briefly activates each LED in the PAD indicator to prove-out and verify correct functional operation of the PAD indicator to the occupants.

    The RCM monitors the PAD indicator "ON" LED circuits for the following faults:

    • Open circuit
    • Short to voltage
    • Short to ground
    • Faulted PAD indicator

    If a fault is detected, the RCM stores DTC B1202:12 or B1202:14 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    RCM B1202:12 Restraint System Passenger Enable Indicator: Circuit Short To Battery A fault is indicated when the RCM senses a short to voltage on the PAD indicator "ON" LED circuit.
    RCM B1202:14 Restraint System Passenger Enable Indicator: Circuit Short To Ground Or Open A fault is indicated when the RCM senses a short to ground on the PAD indicator "ON" LED circuit. An open on the ignition voltage supply circuit to the PAD indicator also sets this DTC.

    Possible Sources 

    • Wiring, terminals or connectors
    • PAD indicator
    • RCM

  2. WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
  3. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
  4. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  5. NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
  6. NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
  7. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

    • Ignition OFF.

    • Connect RCM C310A and C310B.

    • Ignition ON.

    • Using a diagnostic scan tool, perform RCM self-test.

    Yes  REMOVE the fused jumper wire and INSTALL a new PAD indicator. REFER to: Passenger Airbag Deactivation (PAD) Indicator . Refer to the appropriate Information and Entertainment System articles for the procedure. GO to  U12
    No  GO to  U10

  17. U10 CONFIRM THE RCM (RESTRAINTS CONTROL MODULE) FAULT

    NOTE: Make sure all restraint system components and the RCM electrical connectors are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.

    • Ignition OFF.

    • Prior to reconnecting any previously disconnected SRS component:

      • inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
      • inspect wire harness for any damaged, pinched, cut or pierced wires.
      • inspect RCM C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation.
      • repair any concerns found. Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

    • Connect RCM C310A and C310B.

    • Connect PAD Indicator C241.

    • Ignition ON.

    • Using a diagnostic scan tool, perform RCM self-test.

    Was the original DTC retrieved on-demand during self-test? 

    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 RCM. REFER to: Restraints Control Module (RCM) . GO to  U12
    No  In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test. GO to  U11

  18. U11 CHECK FOR AN INTERMITTENT FAULT

    WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

    • Ignition OFF.

    • Disconnect PAD Indicator C241.

      • Inspect connector(s) (including any inline connectors) for corrosion, loose or spread terminals and loose or frayed wire connections at terminals.
      • Inspect wire harness for any damage, pinched, cut or pierced wires.
      • Repair any concerns found.
      • Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

    • Connect RCM C310A and C310B.

    • Connect PAD Indicator C241.

    • Ignition ON.

    • Using a diagnostic scan tool, perform RCM self-test.

    Was DTC B1202:12 or B1202:14 retrieved on-demand during self-test? 

    Yes  This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during self-test. For DTC B1202:14, GO to  U2 For DTC B1202:12, GO to  U8
    No  CHECK for causes of intermittent open, short to ground or short to voltage on the PAD indicator control circuit. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. ACTIVATE other systems in the same wire harness. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test. GO to  U12

  19. U12 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS)

    WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

    • Ignition OFF.

    • Reconnect all SRS components (if previously disconnected).

    • Ignition ON.

    • NOTE: When selecting Restraints from the Self Test menu, DTCs are retrieved from the RCM, OCSM and BECMB.

      Using a diagnostic scan tool, perform

      Restraints  self-test.

    Are any RCM and/or OCSM Diagnostic Trouble Codes (DTCs) retrieved on-demand during self-test? 

    Yes  Do not clear any Diagnostic Trouble Codes (DTCs) until all SRS Diagnostic Trouble Codes (DTCs) have been resolved. DIAGNOSE and REPAIR the Diagnostic Trouble Codes (DTCs). REFER to RCM (DTC) Chart .
    No  The repair is complete. RETURN the vehicle to the customer.
