DESCRIPTION
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.
Customers having this concern should have their vehicle repaired using the following repair procedure.
