Will a Q with flat ...

[GreenQ45a]

Will a Q45 with the Active pkg rise and lower with flat accumulators?

I was under the impression that the cars hight was controlledby the amount of fluid in the system.

Is this correct?

Will the over all hight of the Q lower if just the accumulators are flat?

Can just the Active portion of the Active\PS pump fail?If so how could you tell?

[Q45tech]

Yes........

The Nitrogen in accumulators acts like a spring in series with fluid.....no pressured gas and the fluid just fills the space.

[GreenQ45a]

My Q stands tall normal hight (same as my 93 q45)Actsus Light is on and she won't run the Self-Diag.I tried running the test Soooo many times.

Have the proper amount of A- fluid in res.

just finished:

cleaning engine bay, replacing valve covers, cleaning Throttle body, new Plugs, belts, tracked down and fixed several p\s leaks, cut roters, new pads, bleed brake system.

now its time to worry about the active system.that is the reason I wanted this car.

I DON'T want to convert this car!!! So dont even ask.I think you should trade a non-active Q owner your car before cutting and mutalating such a great car.

I understand the accumelators go flat and I'm going to replace them soon.

before I do I want to make sure the rest of the system it not leaking and no other problems exist.

Can you bleed a Q's active system without a consult?

GreenQ45a .... I'm in the process of getting my active suspension functioning again as well.. Waiting on some parts and trying to find someone to recharge the actuators. Texasoil is MIA and I can't spend $800 bucks per new actuator.. I was hoping Q45tech knew someone else who recharges them.

We blead my active without the consult. My suspension rises and stays level through turns and if you leaned on one side it is compensated for but all 4 actuators are dead and the ride is a tad hard. Check your email Green.

I just spoke with texasoil a few days ago.. Hang in there.. He's the ACTIVE MAN!

[redmanfx]

How can I get up with him? I'm going to have some dead actuators withing the next couple of weeks waiting for some TLC!!

redmanfx[email protected] is my email if you can get it to him.

[GreenQ45a]

Red you got mail.

[redmanfx]

Back at you Green.

[GreenQ45a]

what would keep the car from moving up and down multi-valve?

[redmanfx]

Pumps not working for one. I'm learning more about it everyday myself. As I learn more I'll Pass it on, but I'm still trying to figure it all out myself. Very complex still if you ask me. I'll try to find some links that may help you as I've seen some before.

I am so glad to hear someone state what should be the credo for Q45a owners.

These cars are the rarest of the G50 and should be preserved.

[AZ94Q]

I couldn't have said it better myself..

Just about every Q45/president sold in Japan was an active model... (for a reason)

The system is like the car as a whole.. spend the money, it will suck, but once you get it working right, it will put a smile on your face for a very long time.

[GreenQ45a]

A few months back I started getting rough idle.I checked the coil packs all seemed fine.checked the injectors voltage one seemed a little out of specs.So I put 2 of the 12Gallon fuel system cleaners and 1 20 gallon injector cleaner all @ the same time with only 10 gallons of gas. (all cleaners were Techron)

The rough idle went away by the vary NEXT dayalso that day my I my girl heard a popping sound and my actsus light went off (its been on for a while) and I could feel the system tring to adjust it was working.

That only lasted for a few days.

Can you force the system to run a Self-Diagnosic?I tried turning the key to ON engine not running.started with the system in Normal mode and flipped the switchback and forth 10 times endind with normal and all the dash lights stay on.I was told that the light should begin blinking while the test is being ran.

I have tried running the test flipping the switch from 10-20 times with nothing to show.

ANY Suggestons??

[GreenQ45a]

Yo Red, you said your car still raises correct?

[GreenQ45a]

AZ you did a Texasoil recharge correct ??

[redmanfx]

Yo Red, you said your car still raises correct?

Yes! raises and lowers itself on command! If I have a 300LB passenger it will also compensate for the weight on that side of the car! Brilliant!!

red

[redmanfx]

Green, when you turn your car on it should raise up within 8 seconds or so automatic. And lower when the car is turned off. I have not tried to force a self diag yet and will be getting to a friend who reads Japanese so we can surf the net in the house of the rising sun. I understand we can find whatever we need for the suspension on those sites because they all have active suspensions. If I find anything I'll let you know. I'm still a few weeks off from being able to tear my suspension apart and do some maint. So you may get there ahead of me.

red

[redmanfx]

Sounds to me like you have two problems. The test that you are trying to run checks electrical, pressure, valve functions, not gas. If the test isn't working you may have some those issues. The actuators can be flat(no gas) and the active suspension still work.

red

[GreenQ45a]

Thats what I thought.

I need a way to test the pumps.

Anyone,anyone.

[redmanfx]

texasoil is the guy everyone raves about and he has directions on all this as well. He recharges actuators and is the best person to refer to but I have been unable to contact him.

red

[redmanfx]

Green, texasoil got back to me and sent some word docs. about the active suspension and I can forword them on to you if you want. Let me know. Man am I a happy camper!!!!

red

[GreenQ45a]

Red, thanks for the DOC'S I got em.

did you find out about the ActiveCPU yet?

Red,

I'd be quite interested in any findings of yours. Keep me informed if you come up with anything interesting!

Corey

[GreenQ45a]

Red,

I was reading some of your old posts and something jumped out at me you said

"The oil hydrolics were just purged and refilled. I believe they became air filled and locked, that's why the previous owner decided she couldn't handle the car any longer. Fine now though."

did your car raise and lower when you got it?

or after you purged and refilled?

thanx

[MiniMan]

Red and Green, are you two interested in the active suspension controller?

Corey

[GreenQ45a]

Yes, without a doubt.

BlackRaTT sold me this Q for a great price.Just had a son and still had his 1993 base Q.

he bought it with the ACTSYS light was on and the Active system hadn't worked.

He told me of NICO and of Texasoil's recharge plan.He was going to buy a complete setup from him around X-Masbut the car got a rough idle and started leaking oil so he took it off the road.

I've known him for years and was there when he bought it (and WAS green with invy). and he gave me 1st shot @ it.

He bought it because we both have 93Q's but there both base models. and he wanted to be the first to get an Active Q.

now I have the leaks fixed.

I still need to get the active portion working.

Once the Active system is Active again YES YES YES.I will be buying one.

I have logged on to Nissan Help site and Downloaded the manual (bit by bit).

and asked questions here.

But, no one here has run into a system that won't self test.or there not saying anything.

I will still run the self-test every day and hope one day it works.

and yes I tool it to the dealer and they said I should replace the COMPLETE system suprise suprise.

[MiniMan]

You too eh? $8500 later... no thanks!

Hopefully mine will be up and working before too long as well. If there's anything you think I could help you with Green, just ask.

In the meantime, if I think of anything I'll make sure and give you a shout. All the best.

Corey

[GreenQ45a]

Mini,Did you ever find out where that unit mounts?

I will make us custom harnesses (if needed) to extend the display to center console or wherever we need.

[MiniMan]

Ah, yes we did. No worries, the harness it comes with has enough slack to make it to the dash. I was thinking of mounting mine in the ashtray seeing as though it's only 1/2 DIN. Any idea where you'll mount yours?

All this talk is making me anxious to get my active Q back on the road!

Corey

[GreenQ45a]

I don't think so.

The dealer only tricked me once into buying "the Complete system"

I worked on jet engines with some complex systems and the one thing about "Aerospace Grade" part is they don't "Die" the need to be rebuild @ worst.

Q45a's are made of such a high grade of part.

the dealership techs are lazy.

And most, don't want to work on cars this old anyway listen to Q45 tech.

But that won't stop me MY CAR WILL BE ACTIVE !!
