08-002-232023-03-03. 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.

Some customers may complain about: Intermittent engine no start, Instrument cluster red security indicator light ON, Engine Start/Start Button Amber indicator, light flashing, Battery discharge, Electrical relay buzzing noise.This may be caused by: A key in a purse near a cell phone. The cell phone radio waves may interrupt the immobilizer system. An aftermarket cell phone charger. The charger may produce electrical noise that interrupts the immobilizer system. An aftermarket GPS tracker. Some aftermarket devices that are wired to the vehicles?s wiring harness may create unusual electrical symptoms.
MT-004-182018-10-09. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY; EQUIPMENT. If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal Workshop Manual diagnosis. Aftermarket devices may be the cause of the electrical concern. Ask the customer if any aftermarket devices have been installed. Below are a couple of examples of unusual electrical concerns caused by aftermarket devices.
01-009-18-34522018-04-23. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. The Mazda GR8-1291 is required for all warranty battery testing. If the Mazda GR8-1291 is not used, incorrect battery testing may result in unnecessary battery replacement. Use the following test procedures in this Service Bulletin to test Mazda vehicle batteries and to generate a Warranty Code.
