B00A0 on Ford
Occupant Classification System (Subfault)
B00A0 on Ford vehicles indicates occupant classification system (subfault). Au7o has documented this code across 1 Ford model — most commonly on Bronco. 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.
Common Causes of B00A0
- •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
