Pinpoint Test K: DTC B2292

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) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test  .

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  .

      For 2292_29_CM or 2292_25_CM, GO to  K25.

  22. K22 CHECK PRETENSIONER 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 PID.
      • 2292_30_OD and 2292_31_OD fault PIDs.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the following on the scan tool:
      • PS_PTENS PID.
      • 2292_26_OD and 2292_27_OD 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 a DTC, yet indicates a strong potential for a fault to occur. 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 in-line connectors) and flexing the wire harness.
    • Does any 2292 on-demand fault PID indicate a fault is present or is the pretensioner resistance PID less than 1.50 ohms or greater than 3.04 ohms? 
    • Yes  : DEPOWER the SRS  and REPAIR as necessary.

      Refer to SYSTEM WIRING DIAGRAMS , Connector Repair Procedures for schematic and connector information.

      GO to  K26.

    • No  : GO to K23.
  23. K23 CHECK THE HARNESS AND CONNECTORS 
    • Ignition OFF.
    • 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 in-line 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? 
    • Yes  : REPAIR as necessary.

      Refer to SYSTEM WIRING DIAGRAMS , Connector Repair Procedures for schematic and connector information.

      GO to  K26.

    • No  : The fault is not present and cannot be recreated at this time. GO to  K26.
  24. K24 CHECK SAFETY BELT BUCKLE PRETENSIONER FAULT PID FOR AN INTERMITTENT SHORT TO GROUND 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: DataLogger - RCM  - PID.
    • If the fault PID was reported for the driver safety belt buckle pretensioner, monitor the 2292_28_OD fault PID on the scan tool.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the 2292_24_OD 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 on-demand 2292 fault PID indicate a fault is present? 
    • Yes  : DEPOWER the SRS  and REPAIR as necessary.

      Refer to SYSTEM WIRING DIAGRAMS , Connector Repair Procedures for schematic and connector information.

      GO to  K26.

    • No  : The fault is not present and cannot be recreated at this time. GO to  K26.
  25. K25 CHECK SAFETY BELT BUCKLE PRETENSIONER FAULT PID FOR AN INTERMITTENT SHORT TO BATTERY 
    • If the fault PID was reported for the driver safety belt buckle pretensioner, monitor the 2292_29_OD fault PID.
    • If the fault PID was reported for the passenger safety belt buckle pretensioner, monitor the 2292_25_OD fault PID.
    • Ignition ON.
    • 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 in-line connectors) and flexing the wire harness.
    • Does the safety belt buckle pretensioner short to battery on-demand fault PID indicate a fault is present? 
    • Yes  : DEPOWER the SRS  and REPAIR as necessary.

      Refer to SYSTEM WIRING DIAGRAMS , Connector Repair Procedures for schematic and connector information.

      GO to K26.

    • No  : The fault is not present and cannot be recreated at this time. GO to K26.
  26. K26 CHECK FOR ADDITIONAL SRS DTCs 
    • Ignition OFF.
      • 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).
    • If previously directed to depower the SRS  , repower the SRS  . Do not prove out the SRS  at this time. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - Restraints.
      • NOTE: When selecting Restraints from the Self Test menu, DTCs will be retrieved from the RCM  and OCSM  .
    • Are any RCM and/or OCSM DTCs retrieved indicating a fault? 
    • Yes  : Do not clear any DTCs until all DTCs have been resolved. GO to the DTC CHART  for pinpoint test direction.
    • No  : CLEAR all RCM  and OCSM CMDTCs  . PROVE OUT the SRS  . Repair is complete. RETURN the vehicle to the customer.
