Calibrating the Front Passenger's Weight Sensor Unit
- When the front passenger's weight sensor and/or front passenger's weight sensor unit is replaced, calibrate the weight sensor unit by following the procedure.
- While calibrating the front passenger's weight sensor unit, observe these precautions:
- Make sure all components of the front passenger's seat are correctly installed.
- Make sure all option parts such as seat cover are removed.
- Position the front passenger's seat to the rear most position, adjust the seat height to the lowest position, and adjust the reclining to the most forward position. Do not move from these positions.
- Make sure nothing is on or under the front passenger's seat, and there is nothing in the 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 finish the next step after you start the drive the vehicle.
- Do not expose the front passenger's seat to sudden temperature change.

1. Position the front passenger's seat to the rear most position, adjust the seat height to the lowest position, and adjust the recliner to the most forward position. Do not move from these positions.
2. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (A).
3. Drive the vehicle, and accelerate to 20 mph (36 km/hr), then stop on level ground.
4. From the adjustment menu, select "SWS INIT."
5. Prepare a weight between 55 to 77 lbs (25 to 35 kg) then measure and note its actual weight (M) with a weight scale, machine, and take a note.

NOTE: The accuracy of weight scale must be within ± 2.2 lbs (1 kg).

6. Place the prepared weight on the front passenger's seat.

NOTE: Leave the HDS connected in the Misc Menu.

7. Drive the vehicle, and accelerate to 20 mph (36 km/hr), then stop on level ground.
8. From the inspection menu, select "SEAT OUTPUT CHK." The weight (T) of the front passenger's seat is recorded by the HDS.
9. Calculate the variance between the weight measured by the weight scale (M) and by the HDS (T), using the formula provided.

Variance = (T)-(M)<± 8.6 lbs (3.9 kg)

M: Weight measured by the weight scale

T: Weight measured by the tester with the weight on the seat


- If the variance is ± 8.6 lbs (± 3.9 kg) or less, calibration is complete. Go to step 18.
- If the variance is more than ± 8.6 lbs (± 3.9 kg), remove the seat weight sensors, and reinstall them, then go to step 10.

10. Remove the weight from the front passenger's seat.
11. Drive the vehicle, accelerate to 20 mph (36 km/hr), then stop on level ground.
12. From the inspection menu, select "SEAT OUTPUT CHK." The weight (T0) of the front passenger's seat is recorded by the HDS.

- If the reading on the tester (T0) is ± 6.6 lbs (± 3.0 kg) or less, go to step 13.
- If the reading on the tester (T0) is mean than ± 6.6 lbs (± 3.0 kg), repeat step 3-9.

13. Measure and note the prepare weight (M1) again with a weight scale.
14. Place the weight on the front passenger's seat.
15. Drive the vehicle, accelerate to 20 mph (36 km/hr), then stop on level ground.
16. From the inspection menu, select "SEAT OUTPUT CHK." The weight (T1) of the front passenger's seat is recorded by the HDS.
17. Calculate the variance between the weight measured by the weight scale and the tester, by using the formula provided.

Variance = (T1)-(M1)<± 8.6 lbs (3.9 kg)

T1: Weight measure by the tester with the weight on the seat

M1: Weight measure by the weight scale.


- If the variance is ± 8.6 lbs (± 3.9 kg) or less, calibration is complete. go to step 18.
- If the variance is more than ± 8.6 lbs (± 3.9 kg), replace the front passenger's weight sensors (if they were not replaced before this step), and repeat this procedure from the beginning.

NOTE: If the front passenger's weight sensors were not replaced before this step, replace them before going to the next step.

18. Turn the ignition switch OFF, and disconnect the HDS from the DLC.
