Driver's Seat Position Sensor Operation Check

Driver's Seat Position Sensor Operation Check

Check the driver's seat position after any of these actions:

- Driver's seat position sensor replacement

- Cover plate (front side of driver's seat slide rail) replacement

1. Make sure the driver's seat is at its fall 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 Parameter Information, then Buckle Switch, Seat Position Sensor.






7. Using a piece of tape (A), mark a line 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 0.2 in., 5 mm) until the driver's seat position sensor reads "NOT NEAR." The seat should be about 1 in. (25 mm) from the front.
NOTE: It takes a few seconds for the HDS to display changes, so wait about 5 seconds between each move.

If the driver's seat position sensor 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), and disconnect the HDS from the DLC.
