Ford Mustang · 2005–2010
On 2005-2010 Mustangs, the passenger seat occupant classification system (OCS) can fail or become inaccurate, illuminating the airbag warning lamp and causing the passenger airbag to be disabled. Ford issued Customer Satisfaction Program 15B24 for certain vehicles because the OCS may not properly detect an adult occupant. Owners commonly report an airbag light, 'pass airbag off' staying on with an adult seated, and failed state inspections.
Common Symptoms
- Airbag warning light illuminated
- Passenger airbag off indicator stays on with adult passenger
- SRS fault messages
- Failed safety inspection due to airbag light
How to Fix
Scan the restraints control module for OCS-related faults and verify passenger seat weight sensor operation with IDS or equivalent capable scan tool. Repair typically involves replacing the passenger seat cushion/OCS mat or related seat sensor components, then performing the required OCS calibration procedure. Wiring under the seat should also be inspected for connector damage or high resistance before replacing parts.

Frequently asked questions
What does B2290 mean?
B2290 stands for "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.

The most common causes of B2290 are: Faulty passenger seat weight/pressure sensor or mat, OCS calibration or zeroing required after repair, Damaged wiring or connector under the passenger seat, Aftermarket seat covers or items affecting the sensor, Failed occupant classification module, Restraints control module communication fault.
