Front Passenger's Weight Sensor Unit Calibration

When you replace the SRS unit, front passenger's weight sensors or Front Passenger's Weight Sensor unit, calibrate the ODS unit.

While calibrating the Front Passenger's Weight Sensor unit, observe these precautions:
- Make sure all of the components in the front passenger's seat are correctly installed.
- Make sure nothing is on or under the front passenger's seat.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the windows closed.
- Perform all calibration procedures except, test-driving, in the service bay.
- Make sure the vehicle is on level ground.
- Keep the A/C and the heater off.
- Do not touch the front passenger's seat until you drive the vehicle.
- Do not expose the front passenger's seat to sudden temperature changes.

1. Position the front passenger's seat to the rearmost position, and adjust the recliner to the most forward position. Do not move the seat from this position.




2. Connect the HDS to the data link connector (DLC) (A).
3. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit.
4. Drive the vehicle, and accelerate to 20 mph (36 km/h), then stop on level ground.
5. From the Main Menu, select SRS, then Seat Weight Sensor, then Misc Test, then select "SWS UNIT," and follow the prompts until the initialization operation has been completed.
