Diagnostic Fault Information

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. There are two states of seat position, forward and rearward. The seat position sensor interfaces with the sensing and diagnostic module

(SDM) and 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. The

seat position sensor provides 2 current ranges, one range for the forward seat position and one for rearward seat position. When the SDM receives

input from a seat position sensor that the seat is rearward, and the SDM will not disable stage 2 deployment. When the seat is forward, the SDM

will disable stage 2 deployment. The SDM monitors the seat position sensor circuit and if a fault is detected, the SDM will set code B0079 or

B0080 and disable stage 2 frontal deployment.

Conditions for Running the DTC

Ignition voltage is between 9-16 V.

Conditions for Setting the DTC

B0079 01, B0080 01

The SDM detects the seat position sensor signal circuit is shorted to voltage for 2 seconds.

B0079 02, B0080 02

The SDM detects the seat position sensor signal circuit is shorted to ground for 2 seconds.

B0079 04, B0080 04

The SDM detects the seat position sensor signal circuit is open for 2 seconds.

B0079 05, B0080 05

The SDM detects the seat position sensor signal circuit is open or has a high voltage condition for 2 seconds.

B0079 06, B0080 06

The SDM detects the seat position sensor signal circuit is shorted to ground or an open for 2 seconds.

B0079 08, B0080 08

The SDM detects an invalid signal on the seat position sensor signal circuit.
