Front Passenger's Weight Sensor Unit Initialization

'07 model

Front Passenger's Weight Sensor Initialization

When you replace the SRS unit, the front passenger's weight sensors, or the front passenger's weight sensor unit, initialize the front passenger's weight sensor unit.

While doing 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 nothing is on the front passenger's seat.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the windows and the moonroof closed.
- Do 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 during calibration, until you are prompted to or when you have completed the calibration.
- Do not expose the front passenger's seat to sudden temperature changes.
- Before initializing the front passenger's weight sensor unit, make sure the battery is fully charged.

1. Position the front passenger's seat to the rear most position, and adjust the recliner to the forward most position. Do not move the seat from this position.

2. Make sure the ignition switch is in LOCK (0).

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





4. Turn the ignition switch to ON (II).

5. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit Testing and Inspection.

6. Drive the vehicle, and accelerate to 20 mph (36 km/h), then stop on level ground.

7. From the Main Menu, select SRS, then INITIALIZATION. In the INITIALIZATION Menu, then select SWS Initialization. Follow the prompts until the front passenger's weight sensor unit initialization has been completed.

8. Turn the ignition switch to LOCK (0).

9. Disconnect the HDS from the DLC.
