Circuit Description

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The inflatable restraint passenger presence system (PPS) continuously monitors itself for critical faults. If the PPS determines that there is a communication fault or battery voltage has fallen below a threshold causing a communication fault, the PPS will set DTC 036, turn the passenger air bag status indicator to OFF. Then the PPS will try to communicate with the sensing and diagnostic module (SDM) through a non class 2 communications circuit that a PPS fault is present. The SDM will then turn the air bag indicator to ON, and set DTC B0092 indicating a problem within the PPS and will suppress the deployment of the instrument panel (I/P) module.
