Action Taken When the DTC Sets

* The SDM defaults the seat position sensor to seat forward threshold.

* The SDM requests the instrument panel cluster to illuminate the AIR BAG indicator.

Conditions for Clearing the DTC

* The condition for setting the DTC no longer present.

* A history DTC will clear once 100 fault-free ignition cycles have occurred.

Circuit/System Verification

1. Verify that DTC B0079 08 or B0080 08 is not set.

瀚慖f the DTC is set with the symptom byte 08, replace the appropriate B88 seat position sensor.

2. Ignition ON, observe the scan tool seat position sensor parameter. The reading should be between 2-20 m A. With the scan tool verify that

the seat position sensor parameter is between 2-20 m A.

瀚慖f not within the specified range, refer to Circuit/System Testing.

3. With the seat un-weighted, observe the scan tool while moving the seat to the full forward and then full rearward positions. The seat position

sensor parameter should be continuously between 2-20 m A.

瀚慖f not within the specified range, refer to Circuit/System Testing.

4. While sitting in the seat, observe the scan tool while moving the seat to the full forward and then full rearward positions. The seat position

sensor parameter should be continuously between 2-20 m A.

瀚慖f not within the specified range, refer to Circuit/System Testing.

Circuit/System Testing

Note: When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the

affected component/connector:

* Seat position sensor

* SDM module

* Seat position sensor wiring harness connector

* SDM wiring harness connector

1. Ignition OFF, disconnect the harness connector at the appropriate B88 seat position sensor.

2. Test for less than 10 ohm between the low reference circuit terminal 1 and ground.
