I want to temporarily remove the passenger seat from my 2015 Prius. Does anyone have any suggestions about how to go about doing that? Will it be OK to unplug the harness(es) that run to the seat and plug them back in later?
You'll want to study and follow the procedures for safely working with airbags, including how long to have the 12 volt battery disconnected before you begin to fiddle with the connectors. When you reinstall the seat, there's a procedure in the repair manual for recalibrating the occupant-classification sensor. These are no longer the silly is-somebody-in-the-seat switches from the 1970s; they can tell your adult/child status, sex, and posture in the seat for controlling how forcefully the passenger airbags deploy, and yes, they have calibration that has to be checked. -Chap
Your overthinking it. Unbolt the seat, disconnect the sensors and remove the seat. The sensors you speak of measure the load, as in weight load. Nothing to calibrate. It's not rocket science nor as complicated as you think.
Is it possible, once accessing the tech manuals, to download what you need for future use? I haven't reached the point where I do a lot of my own work on the car, but I also don't know how many times I'm going to want to pay 15 bucks before I want to know if it's possible to obtain the information and store it for later use...
There's no "click here to save the whole megillah", but using some of the signed-up time to download particularly interesting bits for future reference seems to be a pretty common approach around here. -Chap
