Disabling the AHC and AVS systems, no warning lights. (1 Viewer)

So, installing the shocks and springs is the easy part…

I’m down to the passenger rear valve block and then will pull my dissent bumper and slip the pump out.

There are two really long lines that are above the gas tank / exhaust that I’m not mad enough about to extract.

This stuff is seriously heavy (in a robust way). Factoring in the hardware and guards For the accumulators, I suspect it’s 150+ pounds. Will throw it all in a bucket and weigh it once I’m done.

It is so nice having all that free space and not worrying about it getting damaged.

It’s okay to change your mind

After seeing how crusty all of the lines and components are as in removing them, I feel good about my decision.

Ride is dialed in now. IMO high end aftermarket stuff wins on dampening and rebound control. AHC wins for versatility.

Is the ride more or less “tame” without the AHC?

Not exactly sure what tame means to you, but with adjustability of the components I’ve chosen I can relax it to trophy truck or tighten it up beyond AHC sport mode. It’s not as convenient as the selector in the cab but it’s only 4 knobs in my case, and range of adjustment is enormous.

I’m curious if anyone here is running a thick rear sway bar and no front sway bar, similar to what Kai talks about here



Nolothane makes up to a 33mm rear for the LX and I’m tempted to try it without a front sway bar.

No front swaybar and stock rear swaybar for me.

I can't wait for your report on how it handles since the sway bars are supposedly not thick/stiff enough for the non AHC suspension. I just took her out on a 5 miles stretch, and suspension wise it's feels like my 2011 Land Cruiser felt with the stock suspension. I'm going to take her on the...

Slightly longer shocks plus rear sway bar drop brackets made the rear axle boogie in a good way this week.

Wouldn’t quite call it long travel, but notably more than what I was getting stock.

Hey everyone. Didn't want to start a new thread, hopefully all the AHC delete gurus hang out here.

I deleted my AHC a while back in my 2010 LX570 following the procedure and everything is working fine (no warning lights). But I noticed that when I turn on the headlights for the first time after starting up the truck, they turn on and then immediately the leveling thing makes them aim down and so I can't see anything when driving at night.

What should I do ? Is there a way to prevent this ? I thought about adjusting the height of the headlights with the screw but since they were aiming fine before I deleted the AHC, I don't want to "cheat" it if there is a correct way to fix them.

Thanks in advance !

Hi ! Just wanted to give everyone a quick update on this if it can help others. I got TechStream working on my laptop as well as the full 200 series FSM. Scanned the truck and saw a bunch of AFS codes stored in history.

Cleared the codes and now the headlights are pointing straight. Problem solved.

My guess is I must've done something wrong in the AHC delete procedure with the AFS fuse removal and all.
