DTC 1063

DTC 1063

Circuit Description

The inflatable restraint passenger presence system (PPS) is used to monitor the pressure profile of any occupant that is sitting in the front outboard passenger seat and communicate the profile classification to the sensing and diagnostic module (SDM). The SDM will either enable or suppress the deployment of the instrument panel (I/P) module based on the profile classification of the occupant. If the PPS detects this DTC within the PPS, then the PPS will communicate to the SDM through a non class 2 communications circuit that a PPS fault is present. The SDM will then set DTC B0092 indicating a problem within the PPS.
