Circuit/System Description

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.

The inflatable restraint sensing and diagnostic module (SDM) monitors the number of safety components installed on the vehicle. When the ignition is turned ON, the SDM evaluates the number of safety components installed and compares it to the number of components the SDM expects to see on the vehicle with its current calibration. If there is a mismatch between detected components and the components programmed with the SDM calibration, DTC B1019 will set. The components (if equipped) that the SDM will detect include inflatable restraint deployment loops, impact sensors, passenger presence system components, seat position sensors, disable switches, and seat belt switches.
