Component Tests and General Diagnostics
Driver's Seat Position Sensor Operation CheckCheck the driver's seat position sensor 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 ignition switch is OFF (0).
2. Connect the HDS to the data link connector (DLC) (A).
3. Turn the ignition switch ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit.
5. From the HDS Main Menu, select SRS, then Parameter Information then Buckle Switch, Seat Position Sensor.
6. Move the driver's seat all the way forward.
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, check the driver's seat position sensor or the cover plate for damage, and replace parts as needed.
9. Turn the ignition switch OFF, and disconnect the HDS from the DLC.
