Reset procedure for passenger seat weight sensor
Hi, my helm manual doesn't cover the 06-08, does anyone know the reset procedure for the passenger seat weight sensor on a 2007? I replaced the SRS ECU and need to reset the weight sensor. Thanks

I Paid the $10 to access the online service manual, here are the instructions, looks like once again the 06-09 model needs that damn HDS to work on it.
('06-09 models)
When you replace the passenger's weight sensors or passenger's weight sensor unit, calibrate the passenger's weight sensor unit.
While calibrating the passenger's weight sensor unit, observe these precautions:
Make sure all components of the passenger's seat are correctly installed.
Make sure nothing is on or under the passenger's seat.
Make sure there is nothing in the passenger's seat-back pocket.
Keep the windows 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 passenger's seat until you are prompted to or when you have completed the calibration.
Do not expose the passenger's seat to sudden temperature changes.
Position the passenger's seat to the rearmost position and adjust the recliner to the forwardmost position. Do not move the seat from this position.
Turn the ignition switch to LOCK (0).
Connect the HDS to the data link connector (DLC) (A).
Turn the ignition switch to ON (II).
Make sure the HDS communicates with the vehicle and the SRS unit. If it does not, troubleshooting the DLC circuit.
Drive the vehicle, and accelerate to 20 mph (36 km/h), then stop on level ground.
From the Main Menu, select SRS, then Calibration, then Misc Test, then select SWS INIT, and follow the prompts until the calibration is complete.

You're gonna need a trip to a dealer, if the SRS unit wasn't new.
New SRS units that have never done a power on/off cycle don't require the SWS relearn procedure.
Otherwise, make friends with a S2k loving dealer tech.
