    AHC failure only after flush

    I think I may have terms mixed up. Referring to the driver side large Height Accumulator that does not bleed. The other 4 actuators do when I power the pump manually.

    AHC failure only after flush

    When I go to SST I can never hear the pump. To confirm the pump worked I put power to it manually, it works I can hear it whine. In SST I do not hear the whine of the pump. While powering the pump manually I cracked the line off the pump and fluid came through. Also, while having a helper...

    AHC failure only after flush

    Last night while doing the SST, when I was pressing the "up" mode I didn't really hear the pump "whine". Normally every time I started the car the pump would whine for about 30 seconds. Very audibly. Last night I expected to hear a whine in SST but thought it was doing something because when...

    AHC failure only after flush

    I can't rule out a clogged pump.. but when I removed the old fluid from the reservoir and put in the new fluid it worked fine. the vehicle raised and lowered. It was only after I flushed the accumulator and front driver side actuator when the car would no longer raise. I also did them at the...

    AHC failure only after flush

    Okay, I ran the pump another 30 seconds and then moved to the rear passenger side. A small amount of fresh fluid came out with a bubble. I am going to continue this tomorrow morning as it started raining. Questions before I continue: How soon after I see fluid come out of the bleed screw...

    AHC failure only after flush

    Ok an inch worth of clear fluid came through the tube. Looks like there was an air bubble as well. So should I keep repeating this (SST and same front driver side) or repeat the SST and move to the next corner and keep alternating?

    I’ll try bleeding now. Ran for maybe 15-20 seconds or so while I held it down

    AHC failure only after flush

    I take that back, when I press up I can hear the pump slightly and the interior lights dim just a tad, but even if I hold it 10 secs or more the car doesn’t raise. Bummer.

    AHC failure only after flush

    I had to use the diag box in the engine bay. As soon as I start it up the ABS, VSC, and OFF light are flashing. Pressing down 5 times, switching to comfort and then holding up for 10 didn’t do anything though. Tried a handful of times. I just don’t understand why it won’t engage!

    AHC failure only after flush

    Oh man..how am I screwing this up. Am I in the wrong port here? It’s by the brake pedal. I have removed this metal paper clip multiple times. In 4 & 12 just like it says and pressing the down button 5 or more times in 5 seconds after turning it on, but it won’t go into the mode and rapidly flash...

    AHC failure only after flush

    No, thank you for the help. When I crack it open fluid drips out every time. Should I open the pipe off the pump even more? How can I prime it?

    AHC failure only after flush

    I started with the rear passenger corner. A good amount of nasty black fluid drained and the rear end lowered. I closed the valve then turned the car on to pressurize. Pump whined for about 30 seconds, didn’t raise and fluid in reservoir remind the same. I moved to passenger front, a very...

    AHC failure only after flush

    I cracked until just a dribble came out, tighten it back up, fired up the cruiser and no action. Pump still just whines with the full reservoir. Should I keep repeating that? Or should I try to bleed some of the actuators? I only touched driver side front and accumulator before I wrecked...

    AHC failure only after flush

    Thank you. So I definitely introduced air into the system. The reservoir is full, and the truck is completely bottomed out. So when I turn it on it doesn't raise at all. So it is possible to bleed air from the system if the truck does not raise at all on its own? What is the best process to...

    AHC failure only after flush

    Just picked up a 2000 LX470 with 142k mi. There were not records of the AHC fluid being flushed in the past. The fluid was a little low in the reservoir and dark in color. Before the flush I performed the health test, but first I added some AHC fluid to get it to the right level in the...
