Seat Position Sensor: Testing and Inspection

Driver's Seat Position Sensor Operation Check

Check the driver's seat position sensor after driver's seat position sensor replacement.

1. Make sure the driver's seat is all the way forward position.

2. Make sure the ignition switch is in LOCK (0).

3. Connect the HDS to the data link connector (DLC) (A).





4. Turn the ignition switch to ON (II).

5. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit Testing and Inspection.

6. From the HDS Main Menu, select SRS, then Data List.

7. Using a piece of tape (A), mark the location on the seat's outer cover (B) where the front riser cover meets the seat riser (C). The driver's seat position sensor should read NEAR.





8. Move the seat back in small increments (about 5 mm,0.2 in) until the driver's seat position sensor reads NOT NEAR. The seat should be about 55 mm (2.17 in) from the front.

NOTE: It takes a few seconds for the HDS to display changes, so wait for about 5 seconds between each movement.

If the driver's seat position sensor data does not work as described above, check the driver's seat position sensor or the cover plate for damage, and replace parts as needed.

9. Turn the ignition switch to LOCK (0).

10. Disconnect the HDS from the DLC.
