Detailed Description of Error B0048
OBDII error code B0048 is a manufacturer-specific fault code that refers to a problem with the Third Row Right Side Airbag Deployment Control. This code is usually associated with vehicles that have a third-row seating option and are equipped with side airbags. The ''Subfault'' designation indicates that this is a secondary fault related to the primary airbag deployment control system.
The Third Row Right Side Airbag Deployment Control is responsible for monitoring and controlling the deployment of the right-side airbag in the third row of seating. When the system detects a fault in this control, it will trigger the B0048 error code and store it in the vehicle''s onboard computer.
This error code is usually accompanied by the illumination of the airbag warning light on the dashboard. In some cases, the vehicle may also enter a ''limp mode'' to prevent any further damage to the airbag system.
