2005-2010Ford Mustang

B2290 is an OBD-II diagnostic trouble code meaning “Occupant Classification System (OCS) Fault.” B2290 indicates a fault in the Occupant Classification System (OCS), which uses a passenger-seat weight/pressure sensor to determine whether the front passenger is an adult, child, or empty seat so the airbag controller can enable, suppress, or stage the passenger airbag. When the OCS module detects an out-of-range sensor or circuit problem it sets this code and reports it to the restraints control module. Because it can compromise correct passenger airbag deployment, the airbag warning light usually illuminates and the issue should be addressed promptly. This code is most commonly reported on 2005-2010 Ford Mustang, with repair costs ranging from $700 to $1,800.
