Pinpoint Test Ag: B1994/B1995 - Driver Side, Side Mount Air Bag Circuit Open Fault/Driver Side, Side Mount Air Bag Circuit Low Resistance On Squib Fault

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the Pinpoint Test.
  1. AG1 CHECK FOR CONTINUOUS AND ON-DEMAND DTCs 
    WARNING: Restraint system diagnostic tools are for service only. Tools must be removed prior to operating the vehicle over the road. Failure to remove restraint system diagnostic tools could result in injury and possible violation of vehicle safety standards.
    WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
    WARNING: The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
    NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road. 
    NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
    • Enter the following diagnostic mode on the scan tool: On-Demand Self Test.
    • Enter the following diagnostic mode on the scan tool: Retrieve/Record Continuous DTCs.
    • Was DTC B1994 or B1995 retrieved during the on-demand self test? 

    Yes  : This is a hard fault. The fault condition is still present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during the on-demand self test.

    GO to  AG2.

    No  : This is an intermittent fault. The fault condition is not present at this time. GO to  AG6.

  2. AG2 CHECK THE DRIVER SIDE AIR BAG MODULE 

    Yes  : For DTC B1994, GO to  AG4.

    For DTC B1995, GO to  AG3.

    No  : REMOVE and INSPECT the seat side air bag module harness for damage. If a concern is found, REPAIR harness as needed. If no problem is found in the harness, INSTALL a new driver side air bag module. REFER SIDE AIR BAG MODULE  in this article. GO to  AG7.

  3. AG3 CHECK THE DRIVER SIDE AIR BAG CIRCUIT 91S-JA37 (BK/GN) AND CIRCUIT 15S-JA37 (GN/BK) FOR LOW RESISTANCE 
    • Key in OFF position.
    • Depower the system. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING  in this article.
    • Disconnect: Driver Seat C311.
    • Measure the resistance between driver seat C311e-9, circuit 15S-JA37 (GN/BK), harness side and C311e-10, circuit 91S-JA37 (BK/GN), harness side.

    • Is the resistance greater than 10,000 ohms? 

    Yes  : GO to  AG5.

    No  : REPAIR circuit 91S-JA37 (BK/GN) and circuit 15S-JA37 (GN/BK). GO to  AG7.

  4. AG4 CHECK CIRCUIT 91S-JA37 (BK/GN) FOR AN OPEN 
    • Key in OFF position.
    • Depower the system. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING  in this article.
    • Disconnect: Driver Seat C311.
    • Disconnect: RCM C2041a and C2041b.
    • Measure the resistance between RCM C2041a-10, circuit 91S-JA37 (BK/GN), harness side and driver seat C311e-10, circuit 91S-JA37 (BK/GN), harness side; and between RCM C2041a-9, circuit 15S-JA37 (GN/BK), harness side and driver seat C311e-9, circuit 15S-JA37 (GN/BK), harness side.

    • Are the resistances less than 0.5 ohm? 

    Yes  : GO to  AG5.

    No  : REPAIR circuit 91S-JA37 (BK/GN) or circuit 15S-JA37 (GN/BK). GO to  AG7.

  5. AG5 CONFIRM THE RCM FAULT 
    NOTE: Make sure all restraint system diagnostic tools, sensor electrical connectors and the RCM electrical connectors are connected before carrying out the on-demand self test. If not, erroneous DTCs will be recorded.
    • Connect: Driver Seat C311.
    • Connect: Restraint System Diagnostic Tool 501-109 to Driver Seat C311e.
    • Connect: RCM C2041a and C2041b.
    • Repower the system. Do not  prove out the system at this time. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING  in this article.
    • Enter the following diagnostic mode on the scan tool: On-Demand Self Test.
    • Was DTC B1994 or B1995 retrieved during the on-demand self test? 

    Yes  : INSTALL and CONFIGURE a new RCM. REFER to RESTRAINTS CONTROL MODULE (RCM)  in this article. GO to  AG7.

    No  : CHECK for causes of the intermittent fault on the pretensioner circuits. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition key frequently. REPAIR any intermittent concerns found. GO to  AG7.

  6. AG6 CHECK FOR AN INTERMITTENT FAULT 

    Yes  : This is a hard fault. The fault condition is now present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during the on-demand self test.

    CHECK for causes of the intermittent fault at or near the driver side air bag module electrical connectors. REPAIR any intermittent concern found.

    If an intermittent concern was  found and repaired, GO to  AG7.

    If an intermittent concern was not  found and repaired, GO to  AG3.

    No  : CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition key frequently. REPAIR any intermittent concerns found. GO to  AG7.

  7. AG7 CHECK FOR ADDITIONAL DTCs 
    • Refer to the continuous DTCs recorded during Step AG1.
    • Were any continuous DTCs retrieved during Step AG1? 

    Yes  : Do not clear any DTCs until all DTCs have been resolved. GO to the DIAGNOSTIC TROUBLE CODES (DTCS)  in this article for pinpoint test direction.

    No  : RECONNECT the system. If previously directed to deactivate the system, REACTIVATE the system. REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEACTIVATION AND REACTIVATION  in this article. REPOWER the system. REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING  in this article. PROVE OUT the system. CLEAR all DTCs.
