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

WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the 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.
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 taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: 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: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

    • Enter the following diagnostic mode on the diagnostic tool: RCM DataLogger/View and Record All B2292 Fault PIDs
      • Refer to PID list in Normal Operation to view B2292 fault PIDs.
    • Does the original RCM 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  G26.
    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 connector that were disconnected.

      For 2292_31_CM (Pretensioner Circuit Resistance Low, Front Driver Side), 2292_27_CM (Pretensioner Circuit Resistance Low, Front Passenger Side), (2292_30_CM (Pretensioner Circuit Open, Front Driver Side) or 2292_26_CM (Pretensioner Circuit Open, Front Passenger Side), go to  G22.

      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  G24.

      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  G25.

  22. G22 CHECK PRETENSIONER CIRCUIT FAULT PIDs FOR AN INTERMITTENT LOW RESISTANCE OR OPEN 
    • If the fault PID was reported for the driver safety belt buckle pretensioner, monitor the following on the scan tool:
      • DR_PTENS (Pretensioner Circuit Resistance, Driver side) resistance PID.
      • 2292_30_OD (Pretensioner Circuit Open, Front Driver Side) and 2292_31_OD (Pretensioner Circuit Resistance Low, Front Driver Side) on-demand fault PIDs.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the following on the scan tool:
      • PS_PTENS (Pretensioner Circuit Resistance, Passenger side) resistance PID.
      • 2292_26_OD (Pretensioner Circuit Open, Front Passenger Side) and 2292_27_OD (Pretensioner Circuit Resistance Low, Front Passenger Side) on-demand fault PIDs.
      • 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 RCM B2292 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 appropriate SYSTEM WIRING DIAGRAMS article, Connector Repair Procedures for schematic and connector information. Go to  G26.
    2. NO  : Go to  G23.
  23. G23 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 electrical connector:
      • 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 appropriate SYSTEM WIRING DIAGRAMS article, Connector Repair Procedures for schematic and connector information. Go to  G26.
    2. NO  : The fault is not present and cannot be recreated at this time. Go to  G26.
  24. G24 CHECK SAFETY BELT BUCKLE PRETENSIONER CIRCUIT FAULT PIDs FOR AN INTERMITTENT SHORT TO GROUND 
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: RCM DataLogger/PID
    • 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) on-demand fault PID on the scan tool.
    • 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) on-demand fault PID on the scan tool.
    • 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 RCM on-demand B2292 fault PID indicate a fault is present? 
    1. YES  : DEPOWER the SRS and REPAIR as necessary. Refer to appropriate SYSTEM WIRING DIAGRAMS article, Connector Repair Procedures for schematic and connector information. Go to  G26.
    2. NO  : The fault is not present and cannot be recreated at this time. Go to  G26.
  25. G25 CHECK SAFETY BELT BUCKLE PRETENSIONER CIRCUIT FAULT PIDs FOR AN INTERMITTENT SHORT TO BATTERY 
    • 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) on-demand 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) on-demand fault PID.
    • Key in ON position.
    • 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 appropriate SYSTEM WIRING DIAGRAMS article, Connector Repair Procedures for schematic and connector information. Go to  G26.
    2. NO  : The fault is not present and cannot be recreated at this time. Go to  G26.
  26. G26 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: RCM Self Test/Retrieve and Record On-Demand and Continuous Memory DTCs
    • Enter the following diagnostic mode on the diagnostic tool: Clear all RCM and OCSM Continuous Memory DTCs
    • Enter the following diagnostic mode on the diagnostic tool: Self Test/RCM
    • Are any RCM DTCs retrieved indicating a fault? 
    1. YES  : Do not clear any DTCs until all DTCs have been resolved. Go to the SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DTC TABLE  for pinpoint test direction.
    2. NO  : PROVE OUT the SRS. REPAIR is complete. RETURN the vehicle to the customer.
