Pinpoint Test R - DTC: B00D5:12 and B00D5:14

Refer to Wiring Diagram SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.

Normal Operation and Fault Conditions 

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

The RCM continuously monitors the PAD indicator circuits for the following faults:

If a fault is detected, the RCM stores DTC B00D5:12 or B00D5:14 in memory and sends a message to the IPC to illuminate the airbag warning indicator. DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
B00D5:12 Restraint System Passenger Disable Indicator: Circuit Short to Battery A fault is indicated when the RCM senses a short to voltage on the PAD indicator circuit for more than 4 seconds.
B00D5:14 Restraint System Passenger Disable Indicator: Circuit Short to Ground or Open A fault is indicated when the RCM senses a short to ground or an open circuit on the PAD indicator circuit for more than 4 seconds. An open ignition circuit to the PAD indicator also sets this DTC.

Visual Inspection and Diagnostic Pre-checks 

PINPOINT TEST A : B00D5:12 AND B00D5:14 

  1. WARNING: Do not handle, move or change the original horizontal mounting position of the Restraints Control Module (RCM) while the Restraints Control Module (RCM) is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy® and cause serious personal injury or death.
  2. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  3. 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.
  4. 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.
  5. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

  13. A8 CHECK THE RCM (RESTRAINTS CONTROL MODULE)

    NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the fault reported changes, this indicates the RCM is functioning correctly and is not the source of the fault.

    • Ignition OFF.
    • Ignition ON.
    • Using a diagnostic scan tool, perform RCM self-test.
    • DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the PAD indicator disconnected, an open circuit fault is normally retrieved.

    Did the on-demand DTC change from B00D5:12 to B00D5:14? 

    Yes  INSTALL a new PAD indicator. REFER to: Passenger Airbag Deactivation (PAD) Indicator GO to  A11
    No  GO to  A9

  14. A9 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. REFER to: Restraints Control Module (RCM)
      • repair any concerns found. REFER to Wiring Diagram CONNECTOR REPAIR PROCEDURES for schematic and connector information.
    • Connect PAD Indicator C2099 .
    • 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RCM. REFER to: Restraints Control Module (RCM) GO to  A11
    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  A10

  15. A10 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 C2099 .
      • 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 Wiring Diagram CONNECTOR REPAIR PROCEDURES for schematic and connector information.
    • Connect all previously disconnected component(s)/connector(s).
    • Ignition ON.
    • Using a diagnostic scan tool, perform RCM self-test.

    Was DTC B00D5:12 or B00D5:14 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 B00D5:14, GO to  A2For DTC B00D5:12, GO to  A7
    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  A11

  16. A11 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 and OCSM.

      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 Diagnostic Trouble Codes (DTCs) have been resolved. REFER to DTC Chart: Restraint Control Module (RCM) or REFER to DTC Chart: Occupant Classification System Module (OCSM) for pinpoint test direction.
    No  CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs) in all modules. PROVE OUT the SRS. The repair is complete. RETURN the vehicle to the customer.
