Code U0153 Description

The U0153 diagnostic trouble code (DTC) indicates that the vehicle's onboard computer has lost communication with the Side Restraints Control Module on the right side of the vehicle. The Side Restraints Control Module, also known as the side airbag module, is responsible for managing the deployment of the side airbags and other safety features in the event of a collision. When communication is lost with this module, it can pose a serious safety risk as the side airbags may not deploy properly in an accident.
