Circuit/System Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The Inflatable Restraint Sensing and Diagnostic Module (SDM) senses vehicle impacts and provides deployment signals to the air bags and anchor and/or retractor pretensioners when warranted. The Inflatable Restraint Sensing and Diagnostic Module sets DTC B0052 after each command for deployment. DTC B0052 will latch and not clear after 3 commanded deployments by the Inflatable Restraint Sensing and Diagnostic Module. Therefore the Inflatable Restraint Sensing and Diagnostic Module has to be replaced.
