How to Fix
Check VIN status for open recall campaigns and have the pretensioner assemblies inspected and replaced by a Ford dealer if applicable.

Frequently asked questions
What does B00A0 mean on a Ford?
B00A0 stands for "Occupant Classification System (Subfault)." This SRS code refers to a fault in the Occupant Classification System (OCS), which detects the size, weight, and presence of the front passenger (including an empty seat or a child seat) to decide whether and how forcefully the passenger airbag should deploy. The airbag module sets this code when the OCS sensors, weight mat, or related wiring report a fault. With this code active, the passenger airbag may be incorrectly enabled or disabled, so it should be diagnosed for safety. On Ford it is documented across 1 model: Bronco.

The most common causes of B00A0 are: Faulty occupant classification / weight sensor mat in the seat, Damaged wiring or connector under the passenger seat, OCS module needing recalibration after seat service, Aftermarket seat covers or modifications affecting the sensor, Corroded or loose connector, Faulty OCS or airbag (SRS) control module, Poor ground connection.
