B0053 Description

The Inflatable Restraint Sensing and Diagnostic Module (SDM) contains sensing devices that converts vehicle velocity changes to electrical signals. The SDM processes the generated electrical signals and compares them to values stored in memory. When the generated signals exceed the stored values, the SDM performs additional signal processing and compares the generated signals to signals stored in memory. When 2 of the generated signals exceed the stored values, the SDM will cause current to flow through the inflator modules, deploying the inflator modules, and causing DTC B0053 to set.
