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

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. 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 air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of 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.
CAUTION: Use the correct probe adapter(s) when making 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: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the Pinpoint Test.

      For driver or passenger safety belt buckle pretensioner with a short to battery fault (2292_29__CM or 2292_25_CM), go to  G25.

  22. G22 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 following on the scan tool:
      • driver safety belt buckle pretensioner resistance PID (DS_PTENS).
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the following on the scan tool:
      • passenger safety belt buckle pretensioner resistance PID (PS_TENS).
      • NOTE: A resistance PID that reads between 0.9 and 1.23 ohms or between 3.31 and 5 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 1.23 ohms or greater than 3.31 ohms? 
    1. YES  : DEPOWER the SRS and REPAIR as necessary. Refer to SYSTEM WIRING DIAGRAMS , 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 C3201 (driver) or C3202 (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 , 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 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: RCM DataLogger/PID
    • If the fault PID was reported for the driver safety belt buckle pretensioner, monitor the driver safety belt buckle pretensioner short to ground on-demand fault PID (2292_28_OD) on the scan tool.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the passenger safety belt buckle pretensioner short to ground on-demand fault PID (2292_24_OD) 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.
    • Do any safety belt buckle pretensioner on-demand fault PIDs indicate a fault? 
    1. YES  : DEPOWER the SRS and REPAIR as necessary. Refer to SYSTEM WIRING DIAGRAMS , 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 FOR AN INTERMITTENT SAFETY BELT BUCKLE PRETENSIONER CIRCUIT SHORT TO BATTERY FAULT 
    • Key in OFF position.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering .
    • Disconnect the side air bag module electrical connector C328 (driver) or C327 (passenger) on the side with the affected pretensioner.
    • Repower the SRS. Do not  prove out the SRS at this time. Refer to Supplemental Restraint System (SRS) Depowering and Repowering .
    • If the fault PID was reported for the driver safety belt buckle pretensioner:
      • monitor the driver safety belt buckle pretensioner short to battery on-demand fault PID (2292_28_OD).
    • If the fault PID was reported for the passenger safety belt buckle pretensioner:
      • monitor the passenger safety belt buckle pretensioner short to battery on-demand fault PID (2292_25_OD).
    • 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? 
    1. YES  : DEPOWER the SRS and REPAIR as necessary. Refer to SYSTEM WIRING DIAGRAMS , 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 DTCs 
    • Refer to the continuous memory DTCs recorded during Step G1.
    • Were any continuous memory DTCs retrieved during Step G1? 
    1. YES  : Do not clear any DTCs until all DTCs have been resolved. Go to the Supplemental Restraint System (SRS) Diagnostic Trouble Code (DTC) Chart  for pinpoint test direction.
    2. NO  : RECONNECT the SRS. If previously directed to depower the SRS, REPOWER the SRS REFER to Supplemental Restraint System (SRS) Depowering and Repowering . PROVE OUT the SRS. CLEAR all RCM DTCs.
