Seat Position Sensor: Testing and Inspection

Driver's Seat Position Sensor Operation Check

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

1. Make sure the driver's seat is in the full forward position.

2. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

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





4. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

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

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

7. Using two pieces of tape (A), make alignment marks (B) on the upper rail outer cover (C) and the front door sill trim (D) as shown. The driver's seat position sensor should read NEAR on the HDS.





8. Move the seat back in small increments (about 5 mm, 0.2 in) until the driver's seat position sensor reads NOT NEAR on the HDS. The seat should be about 55 mm (2.2 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 for damage, and replace parts as needed.

9. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

10. Disconnect the HDS from the DLC.
