T0: 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 sensors
(see FRONT PASSENGER’S WEIGHT SENSOR REPLACEMENT ), 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.

DRIVER’S SEAT POSITION SENSOR OPERATION CHECK

Check the driver’s seat position sensor after any of these actions:

Driver’s seat position sensor replacement

Cover plate (front side of driver’s seat slide rail) replacement

1. Make sure the ignition switch is OFF (0).

2. Connect the HDS to the data link connector (DLC) (A).

3. Turn the ignition switch ON (II).

4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,

troubleshoot the DLC circuit (see ’08 MODEL ).

5. From the HDS Main Menu, select SRS, then Parameter Information then Buckle Switch, Seat Position

Sensor.

6. Move the driver’s seat all the way forward.

7. Using a piece of tape (A), mark a line on the seat’s outer cover (B) where the front riser cover meets

the seat riser (C). The driver’s seat position sensor should read «NEAR.»

8. Move the seat-back in small increments (about 0.2 in., 5 mm) until the driver’s seat position sensor

reads «NOT NEAR.» The seat should be about 1 in. (25 mm) from the front.

If the driver’s seat position sensor does not work as described, check the driver’s seat position sensor
or the cover plate for damage, and replace parts as needed.

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

E-PRETENSIONER OPERATION CHECK

’06-08 MODELS

1. Shift the transmission to the P position, and release the parking brake.

2. Connect the HDS to the data link connector (DLC) (A).

NOTE:

It takes a few seconds for the HDS to display changes, so wait about 5
seconds between each move.

3. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,

troubleshoot the DLC circuit (see ’08 MODEL ).

4. Sit in the driver’s and front passenger’s seat, and fasten the seat belts.

5. Make sure the SRS indicator comes on for about 6 seconds after turning the ignition switch ON (II),

then goes off. If the SRS indicator does not come on, check for DTCs with the HDS.

6. Start the engine.

7. Select the E-PRETENSIONER with the HDS, and do the E-PRETENSIONER OPERATION

CHECK. Make sure the E-pretensioners retract both driver’s and front passenger’s seat belts several
times.

8. Turn the ignition switch OFF and make sure the SRS indicator goes off.
