Pinpoint Test F: DTC B2292 - Restraint System - SEATBELT PRETENSIONER Fault

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
WARNING: Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which increases the risk of serious personal injury or death.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Supplemental restraint system (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS. 
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

    • Repower the SRS. Do not  prove out the SRS at this time. Refer to Supplemental Restraint System (SRS) Depowering and Repowering .
    • Enter the following diagnostic mode on the diagnostic tool: Self Test/Retrieve and Record On-Demand and Continuous Memory DTCs
    • Enter the following diagnostic mode on the diagnostic tool: DataLogger/View and Record All B2292 Fault PIDs
      • Refer to PID list in Normal Operation to view B2292 fault PIDs.
    • Does the original on-demand DTC B2292 fault PID indicate a fault? 
    1. YES  : INSTALL a new RCM and CARRY OUT programmable module installation (PMI). REFER to Restraints Control Module (RCM) . Go to  F26.
    2. NO  : In the process of diagnosing the fault, the fault condition has become intermittent. CHECK for causes of the intermittent fault in the areas previously worked in, particularly the pins and terminals of any electrical connectors that were disconnected.

      For 2292_31_CM (Pretensioner Circuit Resistance Low, Front Driver Side), 2292_30_CM (Pretensioner Circuit Open, Front Driver Side), 2292_27_CM (Pretensioner Circuit Resistance Low, Front Passenger Side) or 2292_26_CM (Pretensioner Circuit Open, Front Passenger Side), go to  F22.

      For 2292_28_CM (Pretensioner Circuit Short to Ground, Front Driver Side) or 2292_24_CM (Pretensioner Circuit Short to Ground, Front Passenger Side), go to  F24.

      For 2292_29_CM (Pretensioner Circuit Short to Battery, Front Driver Side) or 2292_25_CM (Pretensioner Circuit Short to Battery, Front Passenger Side), go to  F25.

  22. F22 CHECK FOR AN INTERMITTENT PRETENSIONER LOW RESISTANCE OR OPEN CIRCUIT FAULT 
    • If the fault PID was reported for the driver safety belt buckle pretensioner, monitor the DR_PTENS (Pretensioner Circuit Resistance, Driver side) resistance PID.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the PS_PTENS (Pretensioner Circuit Resistance, Passenger Side) resistance PID.
      • NOTE: A resistance PID that reads between 1.36 and 1.50 ohms or between 3.04 and 3.72 ohms may or may not set an on-demand DTC, yet indicates a strong potential of an intermittent fault condition. Make sure to thoroughly check wire harness(es), connectors and terminals as they are the likely source of the fault condition.
    • Attempt to recreate the fault by wiggling the connectors (including any inline connectors) and flexing the wire harness.
    • Does any safety belt buckle pretensioner on-demand fault indicate a fault is present or is the pretensioner resistance PID less than 1.50 ohms or greater than 3.04 ohms? 
    1. YES  : DEPOWER the SRS and REPAIR as necessary. Refer to SYSTEM WIRING DIAGRAMS - E350 SUPER DUTY , Connector Repair Procedures for schematic and connector information. Go to  F26.
    2. NO  : Go to  F23.
  23. F23 CHECK THE HARNESS AND CONNECTORS 
    • Key in OFF position.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering .
    • Disconnect the affected safety belt buckle pretensioner C3338 (driver) or C3135 (passenger):
      • 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.
    • Were any concerns found? 
    1. YES  : REPAIR as necessary. Refer to SYSTEM WIRING DIAGRAMS - E350 SUPER DUTY , Connector Repair Procedures for schematic and connector information. Go to  F26.
    2. NO  : The fault is not present and cannot be recreated at this time. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test.  Go to  F26.
  24. F24 CHECK FOR AN INTERMITTENT SAFETY BELT BUCKLE PRETENSIONER CIRCUIT SHORT TO GROUND FAULT 
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: DataLogger/View and Record All B2292 Fault PIDs
      • Refer to PID list in Normal Operation to view B2292 fault PIDs.
    • If the fault PID was reported for the driver safety belt buckle pretensioner, monitor the 2292_28_OD (Pretensioner Circuit Short to Ground, Front Driver Side) fault PID.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the 2292_24_OD (Pretensioner Circuit Short to Ground, Front Passenger Side) fault PID.
    • DIAGNOSTIC TIP:  When monitoring fault PIDs with the scan tool, it may take up to 2 seconds for the scan tool display to update.
    • Attempt to recreate the fault by wiggling connectors (including any inline connectors) and flexing the wire harness.
    • Does any safety belt buckle pretensioner on-demand fault PID indicate a fault is present? 
    1. YES  : DEPOWER the SRS and REPAIR as necessary. Refer to SYSTEM WIRING DIAGRAMS - E350 SUPER DUTY , Connector Repair Procedures for schematic and connector information. Go to  F26.
    2. NO  : The fault is not present and cannot be recreated at this time. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test.  Go to  F26.
  25. F25 CHECK FOR AN INTERMITTENT SAFETY BELT BUCKLE PRETENSIONER CIRCUIT SHORT TO BATTERY FAULT 
    • If the fault PID was reported for the driver safety belt buckle pretensioner, monitor the 2292_29_OD (Pretensioner Circuit Short to Battery, Front Driver Side) fault PID.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the 2292_25_OD (Pretensioner Circuit Short to Battery, Front Passenger Side) fault PID.
    • DIAGNOSTIC TIP:  When monitoring fault PIDs with the scan tool, it may take up to 2 seconds for the scan tool display to update.
    • Attempt to recreate the fault by wiggling the connectors (including any inline connectors) and flexing the wire harness.
    • Does the safety belt buckle pretensioner short to battery on-demand fault PID indicate a fault is present? 
    1. YES  : DEPOWER the SRS and REPAIR as necessary. Refer to SYSTEM WIRING DIAGRAMS - E350 SUPER DUTY , Connector Repair Procedures for schematic and connector information. Go to  F26.
    2. NO  : The fault is not present and cannot be recreated at this time. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test.  Go to  F26.
  26. F26 CHECK FOR ADDITIONAL SRS DTCs 
    • Key in OFF position.
      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.
    • Reconnect all SRS components (if previously disconnected).
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Self Test/Retrieve and Record On-Demand and Continuous Memory DTCs
    • Enter the following diagnostic mode on the diagnostic tool: Clear all Continuous Memory DTCs
    • Enter the following diagnostic mode on the diagnostic tool: Self Test/RCM
    • Are any DTCs retrieved indicating a fault? 
    1. YES  : Do not clear any DTCs until all DTCs have been resolved. Go to Supplemental Restraint System (SRS) DTC Chart  for pinpoint test direction.
    2. NO  : PROVE OUT the SRS. REPAIR is complete. RETURN the vehicle to the customer.
