    I have a new 4 Runner TRD Off Road, that has a 3" lift and with less than 1,000 miles has the KDSS indicator light on! It is at the dealer for review and repair..... has anyone experienced the same situation? The dealer says it may be a air bubble in the closed system and they need to drain and refill with the special hydrologic fluid. I hope this is not the start of a continual issue. Advice would be appreciated

    Guess the first question is who did the install and how did they do it?

    Hope they didn't take any lines apart.

    It was installed or came from the factory, not sure if it was after market. The lift was after market? The tech said yesterday they were going to drain the fluid and replace it as their may have been an air pocket in the system? Your thoughts?

    Sounds like someone messed up when putting the lift on.

    I wouldn't think it would be a big deal to correct...........unless a 3" lift is too high for KDSS equipped vehicles.

    Does anyone here have KDSS with a 3" lift? Are there any compatibility issues?

    I'm right at 3" no problems. I think someone took some lines off when lifting.

    Hope the previous owner had it installed at the dealer. Could possibly not be covered under warranty if they can prove the lines were taken off.

    If it’s anything like the X-REAS, and I’m not mistaken, if they disassembled the KDSS system anywhere then I’d imagine issues. It’s a closed system somewhat like break lines. At least they are not charging you for it? Anyways I’m no expert on the KDSS but have had my fun with the xreas. Hopefully someone more knowledgeable can chime in!! GL

    Pretty much. The lift install guides always say not to disconnect the lines. Hopefully if it only a spacer the tech doesn't notice it and just fixes it.

    Hi guys, The unit is brand new, off the show room floor. The KDSS came from the factory, the lift (spacers) were after market. Not sure if the tech that did the work on the installation of the spacers did disconnect something but a question to ask the dealer. They said they checked the system and found no leaks? will keep you posted as the findings may be of benefit to someone down the road. Funny, the dealer told me that the repair system for the KDSS sent from Toyota had never been opened and they were trying to figure out how to set it up. Good for those who haven't had a problem but doesn't sound good for me!

    Less than 1,000 isn't new. Someone was driving it a bit. Mine came with 5 miles new.

    I know KDSS came from the factory but whoever installed the lift if they removed the lines to install (which you don't need to) they could of caused this problem. If the dealer identifies the lift as the culprit you could be looking at a bill.

    Hope for the best.

    I’m guessin’ he has put the 1K miles on it. As it was on the showroom floor, they did it or had it done. Their dime.

    Care must be taken not to let the front or rear pistons over-extend when the control arms are at full droop and/or the end-links are disconnected. This is usually done with an extra jack under the piston to limit its travel. When I worked with a shade-tree mechanic to install a set of Bilstein Pro takeoffs on my truck, he explained that allowing the pistons to remain at full extension during the swap could allow an exchange of fluid and air at the seals.

    If the techs simply disconnected the end links and let the bars hang down freely while installing spacers, it may have allowed air in the system through the cylinders even though lines were never disconnected.

    In any case, the dealer should take full responsibility for any problems caused by a lift that THEY installed. If they can't or won't fix the problem, tell them to give you a new truck they haven't fucked with.
