Anyone interested in what happened next, here it is.. took the pump assembly out, flushed it best I could moving fluid back and forth, running it in forward and reverse, put it back in and ran into the same pressure codes, surrendered and had it towed to the dealer, they told me it was a sensor...
Yes, abnormal pressure at pump. I would clear it and the pump would whine and trigger the code again. I tried more bleeding and letting the pump run, each time the system worked less and less down to nothing.
Not 100%. It came close, but everything worked for a few drives and then it went wrong. I am thinking the contaminates had time to make their way in, or air bubble, I am half way through removing the pump unless their is another procedure I should try to restore prime 1st
I replaced my accumulators using the guiadance from this threat and it went well. Had to drill a whole in one, but otherwise a smooth job. After two bleed cycles and drives around the block, my pump started to whine and stopped pumping fluid into the system. I have bled out pretty much all...
it wasn't empty, it was fine, but my LX has an aftermarket undercarriage coating that made it so a light underneath did nothing, also when I go up large hills, like the cottonwood canyons in utah, the cats get really hot and burn some of the coating, smells annoying
my long-time mechanic declined to service my AHC. I ended up bringing it to my local lexus dealership in Utah, they charged me less than $200 for the AHC bleed service. I watched the tech do the service, in very similar fashion to the document shared on this forum, only with the benefit of a...
the system is pressurized, I am not prepared to do a bleed, my mechanic will handle it next week, just looking for a better understanding heading into it, as the majority of possible repairs can be thousands
I lit up the reservoir like a light bulb from the side, can see any fluid, however the AHC light is not on, which is odd. Also the reason I am down this road is for the past few weeks, the rear end drops rapidly after I get off the freeway, only after driving on the freeway, usually at the...
i tried, seems to be some undercoating on the very bottom of the tank that makes it difficult to see if it is bone dry, but i am mostly certain that there is very little. when i have the vehicle shaken while I have a light on the tank, i don't see any move.
i have a 2011 LX with 96k miles, I checked my AHC fluid tank today and it looks empty, bone dry, however the system still works, I have an appt scheduled next week for my mechanic to check it out, hoping for the best! In reviewing the scheduled maintenance documents, looks like it should have...
