This TSB applies to 2011 Mazda vehicles with VINs lower than JM1 DE**** ** 120900 (produced before Dec. 01, 2010).
Some vehicle may experience the airbag system warning light illumination with DTC B00A0:81 (invalid signal to SAS control module) stored in the SAS control module.

- Clear the DTC.
- Was DTC B00A0:81 successfully cleared? If yes, replace the SAS control module. Refer to MS3 online or workshop manual (section 08-10 SAS Control Module Removal/Installation).
