Circuit / System Description
The inflatable restraint seat position sensor is used to determine the proximity of a front driver or passenger seat position with respect to the frontal air bag. The seat position sensor interfaces with the sensing and diagnostic module (SDM). The state of the seat position sensor allows the SDM to disable stage?2 of the frontal air bag for a front seat that is forward of the forward/rearward point in seat track travel. The seat track includes a metal bracket that shunts the seat position sensor magnetic circuit creating 2 states of seat position. The shunted state represents a rearward seat position. The non-shunted state represents a forward position. The seat position sensor provides 2 current ranges, one range for the shunted state and a second range for a non-shunted state. These 2 states are inputs to the SDM, state?1 (shunted) being the rearward threshold and state?2 (non-shunted) being the forward threshold. When the SDM receives input from a seat position sensor that state?1 threshold is reached (seat is rearward), the SDM will not disable stage?2 deployment, if required by the deployment sensors. When state?2 threshold is reached (seat is forward), the SDM will disable stage?2 deployment on the side the seat is forward. The SDM monitors the seat position sensor circuit and if a fault is detected, the SDM will set code B0079 and disable stage?2 frontal deployment.
