a bunch of codes car safe to drive?!!
 

c1108 ABS front left sensor 2
U1000 ABS controller network communication
P3400 ABS NO DTC def. found
P0456 evap emissions
p0700 transmission control system malfunction indicator lamp...
cars running perfectly fine and i get a service light get these codes pulled and get 5 codes with only one im aware of and thats the evap one...wtf any of these dangerous to drive with?? i got upreved this weekend but my tuner said all these codes have nothing to do with the tune...its the ECM not the ECU

Take your car to the dealer and have them use Consult 3 or the ABS/WSS tool to test your left sensor...that is hopefully all your issue is.
If that sensor fails to communicate it will cause your U1000 error. Are you auto or manual?

what about the transmission code

and are these safe to drive on

Ive been hunting gremlins with my ABS/WSS system and ive driven while it hasnt been fully functional with no issues...

Not sure about the tranny error....If you are auto I would be cautious.

nah im 6mt

Well i never had any issues but dont consider that a fact that you will be fine. Maybe someone else can chime in on why that code may have been triggered. From what ive seen alot of sensors work together on this car so when one goes multiple things seem to be triggered.

im thinking from the dyno...front wheels arent moving but back are so maybe that set the abs codes but my tuner said it has nothing to do with it

Never heard of anything like that.. Hope you get everything figured out.

double check with your tuner sounds like the wrong rom file is on the car for you to be getting A/T trouble codes. U1000 is can comm error so it would go off if the ecu is looking for a tcu that isn't there.

it was an uprev tune doubt something was wrong

i know it was uprev, but if your tuner used the wrong p/n base rom to build your tune you would get these issues. Like my car is based of E0A3B (09 base 6mt rev match) yours may be something different. I have always wanted to try 1A33A which is a (10 Nismo 6mt rev match) rom.

I'd try clearing the codes and see if they come back. If the AT code (P0700) comes back, that would be an indication to me that 1slow370 is correct about an improper ROM image. If the ABS codes show back up, then it probably means a trip to the dealer.

cleared em all well see soon thanks guys

re;
 

if the wrong one was put in what do i do? how do i prove to the tuner that it was the wrong one what if they argue the fact and wont fix it for me

Get the tuner to reflash your ROM using the proper image. If you are getting an AT error, that proves that something is wrong in the ECM. Give them a chance to fix it before panicking.


Edit: It shouldn't hurt anything to drive the car with all those DTCs. Just assume that ABS is not going to work and avoid panic stops until you get things sorted out. YMMV

also your evap is the code that most commonly comes up when the gas cap is loose you can try removing and reinstalling the cap to see if that one goes away, what mods do you have other than the tune?

Edit: saw you have the z1 plenum and motor dyne exhaust, area's to check would be the vacuum hoses around the evap solenoid by the back of the manifold, make sure they are all on good and the clamps are on the hoses properly, and the charcoal canister out back if you had to remove the heatshield check to make sure the lines back there didn't get disturbed or worse if the canister cracked or melted.

yeah all the evap stuff was checked but will be re evaluated tomorrow and as far as the abs it works fine....i think thats because of the dyno and the trans code...i called my tuner he said the rom he put in was the correct one

Well if it wasn't reset since the dyno yeah that might have caused your abs stuff

yeah i cleared codes 3 hours ago

It's extremely difficult to troubleshoot via a web forum, so 1slow370 may be wrong about the ROM ... but I wouldn't rule it out just yet. Does your tuner have enough experience with 370Zs to know what he's talking about?

If none of the codes return, then it was probably a glitch somewhere. Check for DTCs often; the order they show up may be important.

Download the FSM and read up on the ABS system. Something in there might put you on the right track. There is a diagnostic section for most, if not all, DTCs.

Trace out the wiring and make sure all wires are intact and the connectors are installed properly.

Getting the P0700 with a MT seems really weird to me. Look at the FSM to see if SRM or something else on the MT is seen by the ECM as being a TCM. If so, look for a loose connector or bad wiring.

Tip: To search the entire FSM at once, most PDF readers will let you put all the files in a folder and then tell Search to look in all files in that folder. A LOT of stuff gets repeated in the FSM, so you'll have to wade through a bunch of duplicates, but it's usually worth it.

yes my tuner is jas from jds motoring hes been tuning nissans for 15 years along with all other cars

only reason i mention it is because tuners that do a lot of one car will save a rom for a base on a similar set up and then copy the maps, so he might have had a 370z na tune done before and gotten the files mixed up and instead of flashing the copied maps into your rom # he could have flashed his starting rom on the car and then tuned that. it gets confusing since there are over 100 different 370z rom's.

i hope thats not what he did he said he didnt . honestly im just gonna get it checked out if it comes back...the po700 that is. all we could do right now is guess

There is lots of stuff that could have gone wrong, hell it could have been from the flashing process and it just needs to be reset. It is hard to say without actually taking a look at the car.

Yep. At this point we're making guesses. We could be close or we could be off in left field. Since the problem didn't show up until after the tune, that seems like the logical place to start, but it could be a lot of things.

Service light came back on only eval code which is good I know that code has been there for awhile. I know what to do but no abs or trans codes so far

So what's the story on the evap code? What's the problem there?

CAN communication errors and ABS problems would probably show up very quickly. My guess is that someone knocked a wiring connector loose (or took it loose on purpose) then replaced the connector. If you don't get any more DTCs after a few hours of driving, I'd say you're OK.

Enquiring minds need to know!. Please let us know what the evap problem is and how you fixed it. It may help someone else out later. If nothing else, you can confirm that a loose gas cap will trigger a warning. TIA

I only got an evap code today no abs or trans code

You need to address and fix the evap code. A healthy car does not have recurring codes. You have a leak somewhere. Go find it and fix it.

:iagree:

Not only is it "tacky" to run around with errors, it may be polluting that fine NJ air. Plus, I don't think one can pass a state emission test with errors showing; will have to be fixed before the next inspection.

yeah its at nissan and all the damn codes came back 3 abs and a friggin trans code that shouldnt even be on because it has to do with a tcm which is only in auto...p0700. whatever. my tuner said the right file and rom and everything was put on going back to what 1slow370 was saying. well jus have to wait and see .

Can you ask him to reflash the ROM he put on just to make sure?
