OK, another Active Problem Codes
Well.. I can't find the codes for active problems while I am waiting for a good repair manual to come along. Can I get the Codes from someone?My code is a 41My active has "bottomed out" and I mean that it is non-functional, not that it is just "stiff" but that it hits every bump and goes all over the place hitting the bottom of the car on bumps.. no damage yet.. the dealer told me that my active sus is gone, but we all know what the dealer says.. "replace it all for $12,000" I am sure that they would love it if we actually did that! Anyways. I wish that someone would post a really clear write-up of active information so that future Q45A buyers would be VERY QUICKLY warned of the potential risk, but would be aware of the nice ride as well..thanks guysChristopher Vigil[email protected]
Code 41 is "pump." It can be caused by the pump failure, or by the accumulator switch ( on the pump accumulator near the radiator) malfunctioning or sensing that there is insufficient pressure in the system. This failure causes the system to run in fail safe mode. Control of motions shuts off, and the system tries to maintain a constant pressure at all four wheels. You feel like a 69 Caddy with worn shocks ( not really, but its a long way from a functioning system...).

NOT AGAIN..
I had some late night munchies and ran to Wendy's for some of their new chicken tenders... and in the drive-thru I checked the codes again.. and it read a 45.. .so can I get some help with that error?
Could the codes be indicative of having had low fluid.. I understand it can take a long time for the codes to be reset and for the fluid to pump out all the air..
Thanks,Christopher Vigil

I have posted about my q.. that I took up to T3 when Q45Tech wasn't around.. and we walked over my car and the guys that were there showed me what I need to do to do it myself..but I still have some questions...especially since the problem might be able to be solved...First of all, I have only one real leak in the active system.. and that is at the driver's rear strut..The fluid was low, and after I put the fluid in, it wasn't "slammed" anymore, but now it just rides like crap.. the active light comes on after the car is on for about 15 seconds.. Diagnostics showed 41 and then 45 and then 41..
Questions are... do I need to get rid of the car if only one of the struts are bad? Does the ACTSUS diagnostics show multiple codes at once, or are these two seperately detected singular instances? What does the Code 45 mean? Could someone post what all the codes mean? Can I do this project myself with out a lift? Can I do one set at a time.. front, then back a week later?Thanks,Christopher Vigil

I'm guessing you will need to have your accumulators recharged at the very least. One of our members (Texasoil) offers the service for around $1000 for all 4, with a warranty and discount on any future work. T-3 has gone to him in the past I believe and can vouch for his work. I emailed him; hopefully he has some insight as to any other problems you might be having and also answer some of your other questions.

I have emailed him too, with no reply yet.. thanks for helping me.. I researched on here and talked to the guys at T3 and they use his recharged accumulators.. supposedly he does more than just the 4 items.. but what about the code.. and if I don't care about the rough ride.. does it affect the operation of the active system?Thanks,Christpoher Vigil

If you have a leaking strut that will have to be replaced first.The texasoil recharge [of nitrogen gas in each shock and accumulator doesn't affect the ride height].......directly.Leaking pumps or leaking lines have to be replaced.....FIRST.
The whole system has to be sealed tight then you can worry about the ride harshness [the recharge].
You really have multiple choices all of them expensive....the barebones retrofit, something intermediate, to a full blown replacement of everything.
A blown suspension active car is worth no more than a blown engine car or a blown transmission car ........maybe $1500 at best depending on paint and interior condition.
The only Texasoil car was a 94 where all 9 components were recharged and substituted. The owner took care off everything having the replacement units dropped shipped to T3 and then reshipping his old units back as cores...The units varied from $250-$200 EACH plus a big refundable deposit on each part and 2 way shipping.
My guess is the whole job ran $1300 + $2300= $3600 but you have to have enough credit card capacity to support the other $2500 in refundable security charges for a week or so if you use air freight both ways.
Packing the removed dirty leaking components for reshipment in sealed plastic bags.......hazardous leaks for transport.
The above system was perfect to begin with just low of nitrogen pressure......there were no other parts replacement.
We had to have the car 4 days for the system to purge.

ok.. so here we are again..I have put fluid in it again $19.95 after tax from the dealer!I am still a little low, but after driving it for a while.. the suspension changed.. I could feel every bump! heavy vibration! Not as bad as when it was riding like a buggy, but worse than yesterday.. I restarted the car... ACTIVE WORKED!!!.. height changed about an inch, maybe an inch and a half..but what about feeling EVERY SINGLE bump in the road.. its like each wheel is responding or something..Let me know what you guys think.Christopher Vigil

active system jolts, etc.
vast majority of strut leaks stop completely when accumulators are recharged.
flat accumulators and rough roads work everything over real hard.
It will ride like a MACK truck with no load (VERY VERY HARSH) with flat strut accumulators.
With low fluid, it will usually drop about an inch from normal height and still ride as above.

Do Q45Tech and Texasoil disagree.. if there is a leak, since I have had to put 3.5 bottles of actsus fluid, will recharging the accumulators fix the problem?
I am told there are 9 pieces that Texasoil can recharge? Do I need to only replace the 4 accumulators, one at each wheel?
Thanks for all you guys help.. I am just trying to get a good grasp on this to resolve if I should buy the book.. or ditch the car... :-)

If you want the system to be as brand new you must make everything act as brand new. Many people [with leak free system] seem to be happy enough with a 4 strut recharge.Because they have no new system to compare too! Good enough is relative and depends on what resources you have.
It is after all incremental you can recharge 4 struts and see how you like it.
As best as I can remember the 9 unit recharge returned the 94 to as new except the tires were different. We then changed the worn upper links and tension rods and retrimmed the ride height and changed his tires to Michelin Pilot and it was darn close to brand new!
It had been 6-7 years since any of out techs had ridden in/driven a new perfect active car. They each drove it 15-30 minutes to refresh their memories.
Most of the ones we see are leaking profusely from the pump or hoses not the struts/accumulator/valves which just dribble.

"but the one resounding question is what is code 45?"
another resounding question is why you don't have a factory service manual or haven't bothered to read/secure one! Considering the complexity of the car.
Code 45 is " Oil level is too low" per page FA-70.There are 30 listed codes and a hundred pages of reading just on this system.
Feel free to stop by T3 and we will supply a manual for you to read on site, and space to sit and take notes.

Just got the car back from Infiniti dealership and here is the list: the active pump failure, valve covers leaking oil/fuel & Coolant bypass hose under intake with V/covers, A/T oil pan leaking from drain plug, actuators internal leakage All 4 & rear control vale. So many things, what should I do.

Valve covers leaks and plenum coolant hose problems are common on any 8 year old much less a 13 year old unit.
I've had the plenum hoses replaced twice [they only last 6-7 years].
Now that the cars are only worth $1,500- $2,500 at resale or $750-$1,000 as a stripper for parts.........when you let them go [by not spending $3,000 per year along the way] and build up $7-10,000 in critical repairs...............bet there is another $3,000 that you didn't list...............you put the money somewhere else.
Even a suspension conversion and the leaks will be $3,500......what condition is the AC or transmission, driveshaft, differential, chain guides, other systems, how well does it pass emissions?

91Q:
how far are you from San Diego?Jerry Tucker San Diego has an excellent repuatrion here with memebers Q's.
It might be worth a drive over there to have him assess a list of priorities.
You plenum leak is expected if car at that milage and originbal valvecover needed to be resealed at some time anyway so those are not unusual expenses.
As for teh active you can decide to convert to a standard suspension as well, Jerry Tucker has done those.
But first I would invesitgate at his location were you are at ( less than dealer).I dont know your budget.If you have large resources I'd say fix all and enjoy a unique/powerful car.If not consider options with possible conversion.

Would i see these leaks because when i had at another shop they did not see this...do you think the dealer might be ripping me off, because i don't see any leaking under the car for the A/T or anything....and i'm going to try to fill up the tank for the active suspension...if that will not work i will take it to jerry tucker.
Thanks Fred
