Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview






Circuit/System Description

The inflatable restraint seat position sensor (SPS) is used to determine the proximity of a front driver or passenger seat position with respect to the frontal air bag. The SPS interfaces with the sensing and diagnostic module (SDM). The state of the SPS allows the SDM to disable stage 2 of the frontal air bag for a front seat that is forward of a forward/rearward point in seat track travel. The SPS is a hall effect sensor that is mounted on the outboard seat track of both the driver and passenger seats. The seat track includes a metal bracket that shunts the SPS 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 SPS 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 SPS 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 SPS circuit and if a fault is detected, the SDM will set codes B0080 and defaults to disabling stage 2 frontal deployment.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

B0080 01

The SDM detects the SPS circuit is shorted to voltage for 500 milliseconds.

B0080 02

The SDM detects the SPS circuit is shorted to ground for 500 milliseconds.

B0080 04

The SDM detects the SPS circuit is open for 500 milliseconds.

B0080 06

The SDM detects the SPS circuit is shorted to ground or an open occur for 500 milliseconds.

B0080 08

The SDM detects the SPS signal circuit is invalid for 500 milliseconds.

Action Taken When the DTC Sets

* The SDM sets a DTC B0080.
* The SDM defaults the SPS to seat forward threshold.
* The SDM commands ON the AIR BAG warning lamp via serial data communications.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
* A history DTC will clear once 255 malfunction-free ignition cycles have occurred.

Circuit/System Testing

Important: When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector:

* The seat position sensor

* The SDM module

* The seat position sensor wiring harness connector

* The SDM wiring harness connector

1. Ignition OFF, if DTC B0080 is current, disconnect the right SPS connector. Refer to seat position sensor replacement in Repair Instructions for location of connector.
2. Remove the SDM connector.
3. Test the low reference and signal circuits between the SDM and SPS. Verify that a short to voltage, short to ground, or open/low resistance does not exist.

• If any of the above conditions are found, make the appropriate repair.

4. Reconnect all SIR components. Ignition ON, use the scan tool to clear the DTCs then recheck for DTCs. Verify DTC B0080 does not set.

• If DTC B0080 was current, replace the right SPS. After replacement, refer to Repair Verification.

Repair Instructions

* Inflatable Restraint Seat Position Sensor Replacement
* Programming and Relearning for SDM setup, and programming. Programming and Relearning

Repair Verification

Ignition ON, use the scan tool to clear the DTCs then recheck for DTCs. Verify no DTCs are set.

If DTC B0080 was current, replace the SDM.
