BULLETIN NOTES This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. Previous TSBs: Date(s) Issued: 08-001/22 08/10/22, 05/02/22, 04/08/22 and 03/17/22 APPLICABLE MODEL(S)/VINS 2019-2023 Mazda3 (Japan built) vehicles with VINs lower than JM1 BP**** ** 618425 (Produced before Apr. 1, 2023) 2019-2023 Mazda3 (Mexico built) vehicles with VINs lower than 3MZ BP**** ** 361665 (Produced before Feb. 10, 2023) DESCRIPTION Some vehicles may exhibit that the air bag warning light turns on or repeats cycles of turning on and off with DTC B1126:13 and/or B1127:13 stored in memory. • B1126:13 - Driver-side side air bag module circuit open circuit or resistance high • B1127:13 - Passenger-side side air bag module circuit open circuit or resistance high This issue is caused by any of the following: • When the driver or passenger moves, a load is applied to the seat back and the load may cause displacement of the mating terminals in the side air bag module connector, resulting in insufficient contact and higher resistance. • The DTC detection level is too sensitive. • The form of the female terminals in the side air bag module connector may cause insufficient contact and higher resistance. To eliminate these concerns, (1) the DTC detection level of the SAS control module has been optimized. (2) Design of the side air bag module connector has been modified. (3) Layout of the side air bag module connector has been modified. Customers having this concern should have their vehicle repaired using the following repair procedure. Page 1 of 15 05/17/2023 04:16 PM tlawrenc REPAIR PROCEDURE 1. Verify the customer concern. 2. Replace the concerned side of the short cord between the side air bag module and the vehicle side harness with a new one and modify the routing of the short cord to the concerned side of the side air bag module according to the Repair Procedure for Short Cord. 3. Reprogram the SAS control module (SAS on MDARS screen) with the Mazda Modular Diagnostic System (M-MDS), using the Mazda Diagnostic And Repair Software (MDARS). Refer to MDARS ECU Reprogramming Procedure. • If the current calibration file name in the ECU FILENAME screen is the same as shown in the Calibration Files Information or with a later suffix, reprogramming is not necessary. • After the reprogramming, pending DTC P2610:00 [PCM] may be stored without the CHECK ENGINE light ON. Be sure to clear DTCs after all repair work is done. • If DTC U2120:00 or/and U2500:82 are stored and i-ACTIVSENSE warning light (amber) turns on after the reprogramming, refer to SA-043/20. • If the Welcome Lamp function is accidently activated while using MDARS, it may also cause this concern. Check and correct as necessary. Refer to the SA-054/20 for details. 3. Clear the DTC, turn the ignition off, and get out of the vehicle. 4. Close and lock the door. 5. Wait for at least ten minutes. 6. Verify the repair by starting the engine and verifying that the air bag/seat belt pre-tensioner system warning light turns on for approx. 6 s and then turns off. NOTE: If any DTCs remain after deleting DTCs, diagnose the DTCs according to the appropriate troubleshooting on MGSS. Repair Procedure for Short Cord Outline Procedure is the same for driver side and passenger side. 1. Remove the seat back trim and the urethane foam pad, t hen remove the side air bag module (1). 2. Partially remove the side air bag short cord. 3. Remove the plastic cover. 4. Perform the following (may be done in different order). a. Work on the plastic cover. b. Assemble a clip band to the short cord c. Work on the urethane foam pad. 5. Assemble the removed parts. 6. Install the seat back trim and the urethane foam pad. 7. Confirm the air bag warning / pre-tensioner warning light s do not stay on.
