What is a Chevrolet Uplander 1st Gen airbag control module?
The Chevrolet Uplander 1st Gen airbag control unit, also known as the Sensing and Diagnostic Module (SDM), is the central control unit of the restraint system. It continuously monitors all airbag sensors and seatbelt pretensioners, collects critical data during a collision, and is largely responsible for the safe deployment of the airbags to provide optimal occupant protection.
This module plays a crucial role in vehicle occupant safety. It coordinates the functions of the driver and front passenger airbags, as well as any side airbags.
As an essential component of the SRS (Supplemental Restraint System), the control unit must always be functional. A defective unit will cause the airbag warning light in the dashboard to illuminate.
Why is the Chevrolet Uplander 1st Gen airbag control module defective?
A Chevrolet Uplander 1st Gen airbag control unit is often reported as defective after an accident because it stores crash data and then requires repair or reset.

A common cause of failure is a stored crash record after an impact. This prevents the airbags from deploying again until the module is reset or replaced.
Internal component defects or age-related wear and tear can also lead to malfunctions. Such problems require specialized expertise to repair the airbag control unit.
