R32 gtr attesa ecu flashing help!

[Semih_Ozdemir]

Hey all

Mute the video before watching as it's loud

My attesa ecu is giving me 1 flash. I've uploaded a video. Any help is appreciated. I've been trying to work tbis out for weeks.

 

Is it front right wheel sensor??

[MoMnDadGTR]

You are correct r32 Gtr manual states front right sensor....try cleaning it, it’s very easy to take off. Just curious are your abs and 4wd light on? I just went through all this shit I’m sure we can solve it quick.

Hi @MoMnDadGTR

Yes the second I start my car I have both awd and Abs lights on 

 

What is the best way to clean these sensors?

Brake-kleen and a wire brush.

ok so you currently are in 2wd.  so lets get this beat. 1. make sure you have a good positive and negative connection to your battery. 2. check the main ground from battery to frame to engine mount. now that the grounds are good make sure the connection for the wheel sensor is actually plugged in. its near the drivers side strut tower in the engine bay ill take a picture for you. as far as cleaning it goes, im sure you could even just wipe it if you remove it, I used brake cleaner.

@GTSBoy thank's mate 

 

I really hope this fixes my issue.  I've been going crazy. Stripped my whole interior looking for cut cable or something

[Semih_Ozdemir]

@MoMnDadGTR have you got Facebook? I can get in contact with you there it'll be so much easier

[MoMnDadGTR]

No I’m pretty old school mate no Facebook, could be a good thread for others if we fix it as well. I know when I was fixing my error codes I found lots of threads with unsolved mystery ha. Here’s a picture of abs connector for right sensor.

[Semih_Ozdemir]

Okay i can confirm my one is connected. But maybe it's not a solid connection whete there may be crap contact. 

 

I'll pull out my sensor and give it a clean after work today. 

My battery was relocated to the  boot after my engine build. My awd was working perfectly before 

 

I'll relocate the battery ground cable as it is now connected to the boot latch nut there. I might try the strut tower? 

[MoMnDadGTR]

I also chased wires like you until I replaced my atessa computer in the trunk of car(atessa control unit). mine had water damage from my rear windshield sprayer leaking and was telling me codes that weren't real. check for power and continuity at that clip as well that I just posted if all else fails. hoping that connector is loose as your issue.

@MoMnDadGTR

I Have swapped out my ecu with my mates one. Same error code

I really hope it's just a sensor or ground issue

[MoMnDadGTR]

if it was working before I wouldn't think move the ground. be patient. my car is setup very simple(no battery relocation or anything) so it was very easy to diagnose and fix. there are some super rebutable guys on here im sure they will step in if cleaning it doesn't work. just a question what ecu are you running? ive heard and seen guys having awd problems with apexi jetro systems...if you still have a stock ecu try a different one if you can get your hands on one

[MoMnDadGTR]

sorry never seen that post....clean and get back to me

[Semih_Ozdemir]

I am running a link g4+ 

 

Okay I'll clean up and check plug and let you know!

this is a link for trouble shooting your error code, im 99 percent sure this will lead you to your issue...the manual has worked every time for me in solving these attesa codes. I would print it off(about 800 pages so use your works printer full r32 gtr manual) if I was you is a gtr bible!

[MoMnDadGTR]

try your mates attessa computer as well see if it solves the issue. I have 3 spares I can sell you one if need be.

Note, the code rings get scrubbed with a wire brush. The sensor itself warrants a more gentle approach.

@GTSBoy

Cheers fellas, 

Easy on the sensor and a good clean. 

I'll re locate earth to strut tower in boot and fingers crossed it's solved 

[MoMnDadGTR]

I highly suggest trouble shooting it with the link I sent you. (It’s straight from r32 gtr manual brotha) This will rule out things quick if you know how to use a multi meter. Way better than guessing but hope it works out.....all you have to do is pull the plugs from the atessa control unit and get to work. 

[MoMnDadGTR]

Could save you from wasting time cleaning your sensors like I did. And if your cleaning one do all 4 don’t cut corners
