Front Passenger's Weight Sensor Initialization: Procedure

How to use this service information .

1. Front Passenger's Weight Sensor - Initialize

   Preconditions 

   • HDS Connected

   Procedure/Specifications 

   NOTE:

   • Before doing this procedure, clear the DTCs.
   • Before doing this procedure, make sure the 12 volt battery is fully charged.
   • Make sure the front passenger's seat and all components of the seat are correctly installed.
   • Make sure nothing is on the front passenger's seat, including aftermarket seat covers or mats.
   • Make sure there is nothing in the front passenger's seat-back pocket.
   • Make sure the vehicle is on level ground.
   • When you perform this procedure, the vehicle temperature must be between 41- 113 deg.F (5 - 45deg.C).
   • When the vehicle is exposed to intense cold or intense heat, move the vehicle inside open the windows, then perform this procedure after one hour or more.
   • Do not expose the front passenger's seat to sudden temperature changes.
   • Do not use the A/C and the heater.
   • Do not touch the front passenger's seat, and keep the vehicle stationary during this procedure.
   • Do not attach the seat belt tongue into the buckle.
   • If possible, do all of the above procedures inside.

   1. Apply the parking brake.

   2. Position the front passenger's seat all the way rearward and lowermost (if equipped with the height adjuster), then adjust the seat-back to the forward most position.

   NOTE:

   Do not move the seat from this position until the initialization is completed.

   3. Select the following menu buttons on the HDS screen in sequence.

   • SRS (System Selection Menu)
   • SWS
   • Adjustment
   • SWS Initialization
   • • -

       Follow the prompts until the front passenger's weight sensor initialization has been completed.

   4. Select the following menu buttons on the HDS screen in sequence.

   • SRS (System Selection Menu)
   • SWS
   • Data List
   • FRONT PASSENGER'S WEIGHT
   • • -

       The weight (T0) of the front passenger's seat is displayed by the HDS. Write this measurement down as "T0" on a piece of paper.

   • If the reading on the HDS (T0) is within +/-0.35 kg (+/-0.77 lbs), go to the next step.
   • If the reading on the HDS (T0) is at or not within +/-0.35 kg (+/-0.77 lbs), do the following and repeat the procedure from step 1.
   • • -

       Confirm that the seat has no interference with surrounding components.

     • -

       Remove the front passenger's weight sensors (if they were not reinstalled), reinstall them, then repeat this procedure from step 1.

   • If after reinstalling the front passenger's weight sensors, the HDS (T0) is still at or not within +/-0.35 kg (+/-0.77 lbs), replace the front passenger's weight sensors, then repeat this procedure from the beginning.

   5. Prepare a weight between 10 kg (22 lbs) - 20 kg (44 lbs), then measure and note its actual weight (M) with a weight scale.

   NOTE:

   • The accuracy of the weight scale must be within +/-1 kg (2 lbs).
   • The weight must be uniformed in shape and size to allow precise placement on the seat.

   6. Precisely place the prepared weight on center of the front passenger's seat as shown.

   7. From the Data List, select FRONT PASSENGER'S WEIGHT. The weight (T) of the front passenger's seat is displayed by the HDS. Write this measurement down as "T" on a piece of paper.

   8. Divide (M) by 2. Write this calculation as "M1" on a piece of paper.

   9. Calculate the variance between (M1) and the HDS (T) with the following formula.

   Variance = (T)-(M1) 

   T: 

   Weight measured by the HDS with the weight on the seat. 

   M1: 

   Half of the weight measured by the weight scale. 

   • If the variance is within +/-2.2 kg (+/-4.9 lbs), initialization is complete. Go to the next step.
   • If the variance is at or not within +/-2.2 kg (+/-4.9 lbs), do the following and repeat the procedure from step 1.
   • • -

       Confirm that the seat has no interference with surrounding components.

     • -

       Confirm that the weight was placed precisely in the center of the seat.

     • -

       Remove the front passenger's weight sensors , reinstall them, then repeat this procedure from the step 1. If the variance is still at or not within +/-2.2 kg (+/-4.9 lbs), replace the front passenger's weight sensors (if they were not replaced), then repeat this procedure from step 1.

   10. The vehicle is in the OFF (LOCK) mode.
