Condition
Some customers may comment that the supplemental inflatable restraint (SIR) lamp is intermittently illuminated and/or the service airbag message is displayed.
The technician may find a repeat history DTC B1011 in the vehicle rollover sensor (ROS) and B0090 0F in the sensing and diagnostic module (SDM) ONLY set in history.
Cause
This condition may be caused by an inflatable restraint vehicle rollover sensor (ROS) that monitored an invalid vehicle speed signal (VSS) on the GMLAN serial data circuit. The invalid vehicle speed signal can be the result of extended engine crank time or a delay in serial data communications.
