After a vehicle collision
10. Position the front passenger's seat to the rear most position, adjust the recliner to the most forward position. Do not move it from these positions.
11. Connect the HDS to the data link connector (DLC) (A).
12. Drive the vehicle, accelerate to 20 mph (36 km/h), then stop on level ground.
13. From the HDS inspection menu, select Seat Weight Sensor, then "SEAT OUTPUT CHK." The weight (TO) of the front passenger's seat is
recorded by the HDS.
-
If the reading on the HDS (TO) is ±6.6 lbs (±3.0 kg) or less, go to step 14.
-
If the reading on the HDS (TO) is more than ±6.6 lbs (±3.0 kg), remove the front passenger's weight sensors, reinstall them, then repeat steps
1-3.
-
If after reinstalling the front passenger's weight sensors, the reading on the HDS (TO) is still more than ±6.6 lbs ±3.0 kg), go to step 1 of
"Calibrating the Front Passenger's Weight Sensor Unit."
14. Prepare a 55 to 77 lbs (25 to 35 kg) weight, then measure and note its actual weight (M) on a scale.
NOTE: The accuracy of the scale must be within ±2.2 lbs (1 kg).
15. Place the prepared weight on the front passenger's seat.
16. Drive the vehicle, and accelerate to 20 mph (36 km/h), then stop on level ground.
17. From the HDS Inspection Menu, select Seat Weight Sensor, then "SEAT OUTPUT CHK." The weight (T1) of the front passenger's seat is
recorded by the HDS.
18. Calculate the variance between the weight measured on the scale and the HDS with the formula shown.
Variance = ((T1) - (TO) - (M1)) < ±8.6 lbs (3.9 kg)
T1: Weight measured by the HDS with the weight on the seat.
TO: Weight measured by the HDS with no load on the seat.
M1: Weight measured on the scale.
-
If the variance is ±8.6 lbs (±3.9 kg) or less, the check is complete. Go to step 19.
-
If the variance is more than ±8.6 lbs (±3.9 kg), remove the front passenger's weight sensor, and reinstall them, then repeat this procedure from
the beginning.
-
If after reinstalling the front passenger's seat weight sensors, the variance still more than ±8.6 lbs (±3.9 kg), replace the front passenger's
weight sensors and the seat riser, then go to step 1 of "Calibrating the Front Passenger's Weight Sensor Unit."
19. Turn the ignition switch OFF, and disconnect the HDS from the DLC.
