Circuit Description

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Sensing & Diagnostic Module (SDM) contains a sensing device that converts vehicle velocity change to an electrical signal. SDM then compares electrical signal with value stored in memory. When generated signal exceeds stored value, SDM deploys air bag and stores DTC. If any air bags deploy while an air bag circuit fault is present, DTC B0053 will set.
