Got 4-whee ahc system check light on at 158k
As i was already planning to change the globes before it appeared, so i though to start it from there.
Order OEM globes (all 4) and OEM AHC fluid.

- Replaced globes

my friend that works at the lexus dealer just went on vacation, i showed him the video and he claim the pump is fine and it might be air in the system. Im waiting on him to return so he can check it out. I hope its a easy fix and not the pump. If the pump is bad i might as well order the globes and the pump from japan, around $1,200 shipped both the pump and globes.

sorry for the late reply, it turned out to be the pump. Few days later after the video that i posted the pump died and no sound or anything. I ordered the pump from impex and i also ordered the globes, i might as well refresh the system even thou the globes were fine. Now it drives smoother than before.
@Chucky313 That is awesome. Any issues ordering from impex with additional tariffs

Impex is the cheapest place to order but they slow on shipment. no tariff on the pump which i received it on August 25th, globes on August 29th i just paid if i remember like $30 or less.
