Pinpoint Test - T DTC: B00B5:11, B00B5:12, B00B5:13, B00B5:1D

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Supplemental Restraint System for schematic and connector information.

Normal Operation and Fault Conditions 

The RCM continuously monitors the driver seat position sensor circuits for the following faults:

If a fault is detected, the RCM stores DTC B00B5:11, B00B5:12, B00B5:13 or B00B5:1D in memory and sends a message to the IPC to illuminate the airbag warning indicator.

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
B00B5:11 Driver Seat Track Position Restraints Sensor: Circuit Short to Ground A fault is indicated when the RCM senses a short to ground on the driver seat position sensor circuit for more than 6 seconds.
B00B5:12 Driver Seat Track Position Restraints Sensor: Circuit Short to Battery A fault is indicated when the RCM senses a short to voltage on the driver seat position sensor circuit for more than 6 seconds.
B00B5:13 Driver Seat Track Position Restraints Sensor: Circuit Open A fault is indicated when the RCM senses an open on either driver seat position sensor circuit for more than 6 seconds.
B00B5:1D Driver Seat Track Position Restraints Sensor: Circuit Current Out of Range A fault is indicated when the RCM measures current outside of an acceptable range on the driver seat position sensor circuit for more than 6 seconds.

Possible Sources 

PINPOINT TEST A : B00B5:11, B00B5:12, B00B5:13 AND B00B5:1D 

  1. 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.
  2. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
  3. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  4. 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.
  5. 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.
  6. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

    7. PINPOINT TEST A B00B5:11, B00B5:12, B00B5:13, B00B5:1D 

  7. A1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.

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

    Was DTC B00B5:11, B00B5:12, B00B5:13 and B00B5:1D 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 B00B5:11 or B00B5:1D, GO to  A2 For DTC B00B5:12, GO to  A4 For DTC B00B5:13, GO to  A5
    No  This is an intermittent fault when present as a CMDTC only. GO to  A10

  8. A2 CHECK THE DRIVER SEAT POSITION SENSOR DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (SHORT TO GROUND OR CURRENT OUT OF RANGE INDICATED)

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

    • Ignition OFF.

    • Disconnect Driver Seat Position Sensor C356 .

    • Ignition ON.

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

    • DIAGNOSTIC TIP:  When viewing Diagnostic Trouble Codes (DTCs) with the driver seat position sensor disconnected, an open circuit fault is normally retrieved.

    Did the on-demand DTC change from B00B5:11 or B00B5:1D to B00B5:13? 

    Yes  GO to  A8
    No  For DTC B00B5:11, GO to  A3 For DTC B00B5:1D, GO to  A9

  9. A3 CHECK THE DRIVER SEAT POSITION SENSOR CIRCUIT FOR A SHORT TO GROUND

    • Ignition OFF.

    • Measure:

    No  GO to  A9

  11. A5 CHECK THE DRIVER SEAT POSITION SENSOR DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (OPEN INDICATED)

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

    • Ignition OFF.

    • Disconnect Driver Side Airbag (Inline) C3051 .

    • Disconnect Driver Seat Position Sensor C356 .

    • Connect a fused jumper wire:

      		 C356-1

    • Ignition ON.

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

    • DIAGNOSTIC TIP:  When viewing Diagnostic Trouble Codes (DTCs) with the driver seat position sensor circuits shorted together, a short to ground fault is normally retrieved.

    Did the on-demand DTC change from B00B5:13 to B00B5:11? 

    Yes  REMOVE the fused jumper wire and GO to  A8
    No  REMOVE the fused jumper wire and GO to  A6
