HEY GUYS!! I'm mad excited right now lol. So I just want to bump this thread to say that I finally had time to sit down and make a little sense of the electrical diagrams in the FSM for the AHC components (the control switch to be exact) and I went ahead and turned on the car's ignition and shorted the LO mode control pin and another pin that's terminated at the AHC ECU (would this be considered a ground?) and IT WORKED, the LO indicator on the dash started to blink. So I turned the ignition off, and turned it back on (to reset ECU command to go into LO) and then shorted the HI mode pin and the terminated pin and the HI mode indicator started flashing! So I turned off the ignition, then started the car and shorted the HI and terminated pins and I could hear the AHC pump working and I could literally see the car adjusting itself. First the front went up, then the back, then the front again. Took less than 15 seconds, just about 10 seconds. I literally fell out of the car because I have never experienced a ride that high lol. IT WAS HIGH!! Like the clearance above the front tires was almost double the normal position!
So just to be sure everything was working in the system, I took the car out on the road (asphalt road, still in HI) and it felt way lighter and way more dynamic, steering was much lighter, maybe I'm just biased lol. Well I got up to exactly just above 30 km/h (19 mph) and the dash light was blinking to N mode. I decided to try my luck and made a u-turn at a T-junction with a rough dirt road (I live in a small estate, there were no other cars present, and Nigeria doesn't really have road laws, so it's fair game in this case). Made sure to be aggressive when entering and exiting the dirt road just to see if the system would die halfway through to N (I'm paranoid like that) and the car settled perfectly in N, took just about 15 seconds to get back to N. Got back to my yard, parked the car, and it was really sitting in N, without any input from me.
This system is 17 years old, it's been sitting in N position for those 17 years (I would know since I'm [slightly] older than the car and it's the car that got me into cars lol), I literally put it into HI for the first time in its life and it had 0 issues (all after 17+ years of massive off-road abuse; here's proof of abuse: 2004 LX470. Wrecked Axle. Is it safe to drive? (Pics and Vid attached)). No leaks, no stalls, no trouble getting into or out of HI. This car really is shaping up to be the most efficient, cost-effective car I've ever sat in.
Well, just wanted to share that it is indeed the switch that is faulty and it will be (hopefully!) replaced this coming Thursday. Big Thanks to everyone that has been with me on this crazy journey. Took me 2 months (including time-off from this because of school/life in general) from the beginning, when the AHC system didn't seem to exist except in hardware only and the car was a nightmare to drive (the fix was a silly 20 amp AHC-IG fuse that a silly person didn't leave intact), to the end, where the AHC is one dead switch away from being fully functional.
BIG CHEERS!!!
(P.S. The fluid was at the max level when the car was sitting in N, but was way below minimum level when the car was sitting in HI. I have confirmed it's not colorization of the reservoir. Problem? or just needs more fluid?)
