Service Campaign TX8 SRS B1620 DIAGNOSTIC LOGIC UPDATE

Description: The SRS airbag warning light on the instrument panel
illuminates for approximately 6 seconds after the ignition is turned ON, and
then turns OFF. During this time, the Airbag Control Unit (ACU) conducts
self-diagnosis. On certain vehicles, if the ACU senses sufficient vibration
during the diagnostic period (from a vehicle door being slammed, for
example), the SRSCM may erroneously detect a fault and illuminate the airbag
warning light accompanied by DTC B1620 (internal fault).
