    Before I got everything back together I had to put the front sub frame on so it could be towed home as I was going through a divorce.

    Factory service manual made it sound like the sway bar could be installed with the subframe attached, so I neglected to install it to save time.

    I spent 2 hours last night after removing the entire exhaust and steering gear twisting and contorting the damn thing, but it will not go in without removing the subframe.

    I got a more stiff Corrolla front sway bar that I've been procrastinating on installing on my Gen2. Maybe that's why I've been avoiding it? :) But according to all the posts I've read on here, you just need to disconnect the exhaust at the header, the wheels and all the mounts for it? Is there an additional bracket down there (subframe) that needs to be removed?

    With the subframe attached, there is limited clearance to bolt in the sway bar itself. There is also limited clearance to unbolt the steering gear.

    This is a photo of the subframe with the attached parts.

    You have to insert the sway bar and flip it back around. There isn't enough room to insert the sway bar in the correct position.
    There also isn't enough room to flip it around, it hits on the floorpan/firewall area.

    Dang... That looks like so much more work than I thought? I wonder why no one has mentioned this? I mean I've read every Gen2 thread on here regarding sway bar upgrades and never once read this?

    I just don't see the point of upgrading the sway bar on the Prius especially the front.

    I just came here to find out FSM stood for, and why it lied. Anyway, attached Repair Manual excerpt attached, just in case it's any different:

    I kinda wonder how these manuals are written. Like is there a team of people taking entire cars apart to write these?
    Also in one of the DTC workups for the throttle body, one of the resistance values is incorrect. I know this because it was the same on my old throttle body position sensor and a brand new one.

    there might be an updated version that's not probably out in the internet yet. Same issue with the 8mm triple square head bolt in the FSM, it's actually 9mm.

    The service manual also lies about where the certification ecu aka immobilizer is. That was a huge pain in the butt when I was dealing with an (unknown) corroded wiring issue.

    Took a ton of digging around online, like multiple days going through old posts and finally a russian youtube video showing a prius teardown led me to its actual location.

    Might be worth starting a thread, that way others don't have to go thru similar efforts.

    Is it not located as pictured below?

    Good catch. Germans use "triple square" 12 points that have 90° angles.

    Toyota's "double hex" 12 point has 60° angles.

    Completely different tools. They will not interchange.

    I do not know. It depends on what you mean when you say "immobilizer". It also depends on who does the translations for any given section of the factory service manual.

    There's the "transponder ecu", the "certification ecu", and the "ID code box". Can't keep "which part is what" straight in my head.
