Diagnostic Fault Information

Circuit/System Description

The seat position sensor is used to determine the proximity of a front passenger seat position with respect to the inflatable restraint I/P module. The

seat position sensor is a hall effect sensor that is mounted on the seat track of the front passenger seat. The seat position sensor is connected to the

sensing and diagnostic module (SDM) with a low reference and a signal circuit. The SDM uses the state of the seat position sensor to determine the

need for a stage 2 deployment of the inflatable restraint I/P module. When the seat is in the forward position stage 2 deployment is disabled, and

when in the rearward position stage 2 deployment is enabled. The SDM monitors the RF seat position sensor signal circuit and if a fault is detected,

the SDM will set DTC B0080 and defaults to disabling stage 2 inflatable restraint I/P module deployment.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

B0080 01

The SDM detects the RF seat position sensor signal circuit is shorted to voltage for 500 milliseconds.

B0080 02

The SDM detects the RF seat position sensor signal circuit is shorted to ground for 500 milliseconds.

B0080 04

The SDM detects the RF seat position sensor signal circuit is open for 500 milliseconds.

B0080 06

The SDM detects the RF seat position sensor signal circuit is shorted to ground or an open for 500 milliseconds.

B0080 08

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