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 full 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 (see page 11-204).

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

Prameter Information, then Buckle Switch, Seat
Position Sensor.

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

0.2 in., 5 mm) until the driver’s seat position sensor
reads NOT NEAR. The seat should be about 25 mm
(1 in.) 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 data does not

work as described, 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.
