General Troubleshooting Information (cont’d)
A
When the front passenge’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.
• 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.
