Condition

Some customers may comment on receiving unwanted calls from the OnStar® Center.

Cause

During certain extreme vehicle maneuvers, the vehicle SDM may mistakenly detect a crash event and generate a call to the OnStar® call Center. The OnStar® advisor is connected to the vehicle to see if everyone is alright and if a request for emergency help is needed.

Correction

A revised SDM Operating System software has been developed to address this issue. Reprogram the Sensing and Diagnostic Module (SDM) with the controller option described as "SDM Sensing and Diagnostic Module" under Operating System using the TIS2WEB Service Programming System (SPS) application. As always, make sure your Tech 2® is updated with the latest software version.
