700h AHC Adjustment Sensors (2 Viewers)

[Vicgeorge]

While determining fitment for wheels/tires I noticed the driver side adjustment sensor is in the down position. I thought they must have adjusted them from the factory for the OT. When I checked the passenger side, it is adjusted to the up position. Am I missing something?

I noticed the same thing on mine. I haven't messed with them yet. On the 200, IIRC, the front and rear were reversed (up/down). I didn't check the rear on my mine but maybe they're reversed side to side on the 600.

I didn't even think to check the rear... Glad to hear it's likely (though oddly) normal.

They are not reversed on the 300. All the way down for more lift, all the way up for less lift… both front and rear.

Well that's not good. Wonder why ours are both opposite left to right.

Can anyone else check theirs?

 

[URJ150L]

One of mine on the front was 3/4 of the way down… all the others were all the way up. Good news is that it’s easy to fix

I have a hard time believing these are set incorrectly from the factory. Are we sure they're all supposed to be set to the same level on both sides/corners?

 

[Vicgeorge]

I agree with you. I think, over time, as folks have a chance to look at the factory adjustments, we’ll find there is manufacturing integrity. And perhaps even the logic behind it…

@Docyota , @Canyonero @Sinister @Joe T @Oakleyguy Can you guys take a look at yours?

Not a 700 but here are the shots of my 600 AHC
Took photos clockwise - driver front, passenger front, passenger rear, driver rear.

On my 600, my driver side was near the bottom and my passenger side was near the top, just like the OP's.

In Normal, both my fronts measured 34" from ground to bottom of wheel well using a level and measured at the middle of the wheel.

In H1, they were both 35".

As @URJ150L posted, down is more lift and that's what i got. With both pushed all the way down, I'm now getting 35" on both in N and 36" in H1. (sometimes an 1/8" or 1/4" higher)

What's strange to me is that both sides were equal heights originally despite the sensors being set opposite. I spent a while moving just the driver side up and down and cycling though and measuring and both sides seemed to respond but i didn't get major movement until pushing the passenger side down. I'm guessing there is some logic where it levels the front side to side and the lowest sensor setting rules.

I didn't try drivers side all the way up with passenger all the way down. Wonder if that would give more lift. With the extra inch now with both pushed down, the rake is almost completely gone.

Here are mine pushed all the way down.

Thanks. Those rears are harder to find. That's how my front's looked. My rears are both similar to each other and more in the middle.

Basically no rake now. Falken 285/65R18

Normal (35" high):

H1 (36"):

H2 (38"):

Can you grab an H2 measurement while in 4LO? @mrlittlejeans

will do. Out of town right now but will be back end of the week and can do then.

 

[Sinister]

I don’t have the fancy adjustable suspension.

 

[billjamin]

Just checked and mine are staggered too.

 

[Poorbong]

I just checked my front and they aren't equally adjusted. Been thinking of setting my front all the way down to get rid of the rake.

Not I’m curious.
Toyota/Lexus don’t do random things with their engineering.
There has to be some logical explanation.
The only logical solution I can come up with is as follows:
We know that it has pre-determined heights for L N H1 and H2 and that they can vary based on sport, normal, comfort. We also know that there is some height differences based on being in 4 wheel high or low.
The one setting we have no control over is when the vehicle believes it is stuck and the manual says it will raise itself to a beyond H2 height automatically.
My theory therefore is that the different settings we are seeing driver and passenger side (with driver being the primary reference) allows the system to use the passenger side setting as a reference to set “max get me unstuck” lift without over extending.

Not an engineer, but I’d want to know the reason they are adjusted the way they are before I tweak the setting.
