ahc

I’ve been trying to diagnose an undercarriage rattle for a bit. I’v suspected it’s related to the AHC system for a while. I just discovered what I think is crucial information: the rattling stops when I put the AHC in high mode. When in neutral, I hear a hollow rattling/clanking when I drive...

I've been through a million of these over the years, so I apologize for creating another. But it's difficult to find answers to specific issues/questions. My AHC has failed - stuck in the flashing OFF now, code is C1762 - abnormal oil pressure for pump. My front height sensors are at -2" and...

Just recently installed a Ironman front bumper with a Bandland APEX 12K winch, and then finishing up the refreshment of the front suspension, including new UCA, new bushing for LCA/AHC shock and so on. Having gone through some of those existing AHC/TB posts, I realize I may have to deal with...

pls tell me i didn't swap the fronts and rears... so i just replaced my globes and i didn't triple check as i was reinstalling to make 1000% sure i was putting the rears on the rear and fronts on the front. but now that it's done, i was looking at the old globes and i noticed one of the smaller...

I have a 2007 LC100 with a perfect AHC system. Looking to do a AHC delete in next few months... I am trying to sell the entire AHC system, or part it out. If anyone is interested, please DM me. PRICE TBD, DEPENDING ON FULL SYSTEM OR INDIVIDUAL PARTS. Will ship, cost TBD and must be paid by buyer.

After 3+ years the AHC is striking again. On a short 15 min trip this morning I felt the rear end suddenly very stiff right away out of the driveway jarring the vehicle over small bumps, about 2 miles later the AHC off light started flashing. Upon arrival to my destination I found the rear end...

I'm a big fan of AHC and have always maintained the system myself on my lX470 and now LX570 vehicles. Today, I had my first real hiccup in my AHC history and it made me wonder a bit about the chemistry of AHC fluid and the rubber (is it rubber?) membranes in our AHC globes. It's getting a bit...

Hello guys, I'm new to forums and have started to learn about ahc. My car is a 2018 lx570 with 50k miles on it. Last month when I do my inspection, the dealer informed me my front suspension is leaking and needed to be changed. the price is sky-high and scares shxxt of me. I found some...

I am not sure if someone already mentioned it, but I would like to share my experience with ahc My car is a 06 lx with 262600 miles, super neglected by pervious owners (original tb and wp for 250k miles) So I got new globes and new fluid and rebuild the ahc pump was all gunk up. But the ride is...

I am at it again. I was so anxious today that I was changing all those bushes under my car. I expected to get the best experience after the change. Note that I was already having a very good experience, and in fact I should not have bothered to change anything - but there I was. All rubber...

Is there a HAC (High Altitude Compensation) circuit on these trucks? Or atmospheric pressure sensor? And if so, does anyone have a pic from the FSM that shows the components in the circuit? The issue is that above 9000 ft, the VSC and check engine lights come on, then go back off when I go to...

Quick question: What is the total vehicle height when AHC is lowered, all stock preferred. Thanks! Andre’ “Tight fit covered parking!”

I recently acquired a 2007 Land Cruiser. 50k miles. Excellent condition overall. I was following the handy AHC guide here and doing some poking around with Techstream and everything looks pretty good there however... the steering angle sensor reading is wrong. When the wheel is pointed straight...

Tried installing my new WKOR sliders yesterday but had to give up because I ran into a thick hard line on the driver's side that wouldn't budge and I didn't want it touching the slider directly. I'm assuming it's AHC? Wanted to bend it out a few mm for the u-bolt to clear but it feels...

Hello, I have a 2003 LX470. I currently am letting my father drive it as he needs something better in the snow. He is telling me that the AHC was not working. I came out to see what he was talking about. The truck was very low, he said it was higher than he’s ever seen in the morning before. I...

Anyone have the link of the AHC sensor programming? Not the manual adjustment to the physical sensor but digitally adjust the sensors and get readings via tech stream. looking for a procedure doc or a thread I can follow and print out. Thanks.

Hi all I’m on the north coast of Cornwall on holiday and I’ve got a burst AHC pipe somewhere, my reservoir is empty Is there anyone out there that could help or recommend a garage not an easy situation at this time of year, not to mention having our dog and wife with me. Thanks in advance

I'm located in Maine and am looking to pickup a 2006 or 2007 LX470 - No LC's at the moment Cash in hand and willing to travel for the right vehicle with a patient seller. AHC still installed (not bypassed or removed). The more unmodified the better. No rusted vehicles please. Clean title is...

Hi, I m new to the forum. I was gifted a 2005 lx470 from a family friend and has been my daily driver for about an year. Recently, I got the AHC off light blinking, so I opened up the hood to check the fluid level. It have enough fluid, but I found those wires in a really bad shape. Anyone know...

Gents, do we have a comprehensive AHC thread already started? If not, I'd like to contribute to the forum here by spearheading this. Goal of the thread is to be a single all encompassing AHC resource. Items in it would be, but not limited to: stock operation of the system, maintenances, how to...
