## Other bulletins for the same vehicles and component

- [08\-002\-23](/bulletins/10232280.md), 2023-03-03, Service bulletin: ELECTRICAL SYSTEM:12V/24V/48V BATTERY; AIR BAGS; AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION:STATUS INDICATOR LAMP/LIGHT. Some customers may experience the airbag warning light ON with DTC B00A0:09 stored in the SAS control module memory when the battery voltage is low. DTC B00A0:09 \(Occupant classification sensor internal signal output unstable\). This concern is caused by the low voltage detection time of the occupant classification sensor \(OCS\) being too short during cranking, which causes detection of the DTC unnecessarily. The concern occurs more often in colder weather when greater electric current is consumed to start the vehicle. To eliminate this concern, the OCS has been modified to avoid unnecessary DTC detection. NOTE: Even if the voltage is recovered after the engine is started, the airbag warning light stays ON during the drive cycle. When the battery voltage becomes stable after the engine is started, the airbag system will operate normally.
- [SA\-010\-22](/bulletins/10209753.md), 2022-04-06, Service bulletin: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Some customers may experience the 12V battery under the hood is discharged and the vehicle will not turn on. This can be caused by frequently opening and closing the doors \(which will wake modules up and cause a drain on the 12V battery\) or leaving the vehicle in the Accessory or Power On mode. The Power button has 4 positions \(modes\).
- [DRW41a](/bulletins/10200947.md), 2021-09-03, Service bulletin: ELECTRICAL SYSTEM:12V/24V/48V BATTERY; EQUIPMENT:ELECTRICAL; COMMUNICATION:MANUFACTURER TELEMATICS. DRW41 \- TELEMATICS COMMUNICATION UNIT \(TCU\) CONCERN \- BATTERY DRAIN AND CONNECTED SERVICES. On certain subject 2021 MY CX\-5 \& CX\-9 vehicles, a battery drain concern could occur due to the Telematics Communication Unit \(TCU\) not going to sleep. In addition, some vehicles were repaired under the cancelled campaign SSPC6, which caused Connected Services to no longer work. This Dealer Rework will repair all concerns to ensure the battery drain concern does not occur and restores Connected Services, if disabled from a prior software update. All Mazda dealers will update the subject vehicles with improved TCU software. This campaign will be expanded to include additional Mazda3 and CX\-30 vehicles at a later date, please watch for additional announcements.
