Body Codes (B Codes)

Body codes cover comfort, access, and restraint systems: airbags and seat belt pretensioners, climate control, power seats and windows, central locking, lighting, and the instrument cluster. Airbag-related B codes turn on the SRS warning light and mean the restraint system may not deploy correctly in a crash, so they deserve prompt attention even though the car drives normally.

Reading B codes requires a scanner that supports body systems; a basic engine code reader will not see them.

There are 300 generic B codes in the database. Browse the complete list on the codes list page.
