That's what I did years ago, got used non-AHC from a LC100 for free.

And then ... has it been okay?

Non AHC LC coils are a good choice if you are REALLY heavy. King AHC springs are a better choice for most.
Absolutely.
With the original springs, when we were towing our camper trailer and car loaded with campig gear and a full tank, the system went to Low.
This is as mentioned above due to the maximum weight the system can handle.
Since I changed the springs, I never had that issue anymore.
Especially now I have a long range tank and dual spare wheel carrier installed.
The system goes from N to L and from N to H all the time.
Why not?

And with fuel tank nearly empty? Just asking?

Don't see a reason why you can't measure it?
Not sure what the manual says, but it will probably say with fuel.

The manual says with full tank of fuel, but understandably and obviously no mention of third row seats.
I removed my third row seats a few days ago and they are really heavy. So I was wondering what effect their removal could have while measuring neutral pressures.
It will have an effect as they are about 30kg each.
However if you drive around mostly without them, it's best to use Techstream without them as you need to set up the system to your driving situation.

My normal driving will be myself alone in the car with half-full fuel tank, and no third row seat.
Should i therefore measure and adjust neutral pressures under this condition?
Of course, once every so often, i do travel with three or four passengers with full tank. I do not overload or tow.

Anyhow, we resolved the issue yesterday - albeit not in the most favourable way.
Clearly, there was something wrong in the pump (i mean within the pump, motor, pressure sensor, switches, tank, etc assembly). The system worked very well after trying another used pump assembly (not sure of the term to use, but i mean the whole thing including reservoir tank).
Prior to changing the above, another mechanic had tried to disassemble and clean the pump, but it did not work. I suggested to change the O rings but they said it was ok. I also suggested to change the pressure sensor, but it was not possible.
Since i was also under pressure of time, i ended up paying for the pump (full set including pump, motor, pressure sensor, switches, tank, etc) that was working. Expensive, but it was a relief. I am keeping my old pump for future use as i suspect there is just a small problem with it.
I am relieved but not yet celebrating.

What did not work? Mechanics ability to disassemble and clean the pump? That’s a shame.
If that’s the same mechanic that couldn’t disassemble ams clean the pump, that’s even more of a shame.

Sorry for lack of clarity. Ths new mechanic of yesterday disassembled and cleaned the pump, and put it back. But pressure was still too low, so it could not raise the car from L.
Thats when we tried another pump and it worked.

IMO, he should not have said the O rings were Ok. There’s no way of knowing older O rings are OK without replacing them. That could be a crazy inexpensive solution, for your mechanic to purposefully disregard, if you asked him about replacing them.
There is only like one thing in that block of metal that can go wrong or malfunction… the O rings.

The problem could as well have been the pressure sensor, or mortar, or anything else around there.
The problem comes in when a mechanic claims or thinks whatever he says is correct, even if he is unsure.
Being stubborn is only a virtue if you're right.
I'm glad to hear you got it resolved and would love to know what caused the old pump assembly to not work correctly.

Sure, i am happy too.
I think the only way to know what caused the problem is to test the components one by one. At this point, i think we can guess that one (or more) components are faulty.
Or it could even be that the mechanics have not been re-assembling the pump correctly after cleaning ... remember i said earlier that they had so far disassembled, cleaned and re-assembled four times (over just a few weeks).
The very first mechanic who did it three times was cleaning the pump using WD-40 lubricant. This last mechanic of yesterday cleaned it using suspension fluid. Not sure what the best practice is.
