Ecu Error Codes

[CATKICKER]

Hi Guys, I am having a little issue with my idle still. I have replaced my O2 sensor, cleaned and resoldered my AFM, Cleaned my ACC Valve and reset my ECU.

The problem is that it idles at 1500-2000rpm for about 5secs and then drops down to normal! It is an RB20det in an R32 GTS-t. I have quite a few mods but don't think that is relevent at this stage.

Resetting the ECU has fixed the problem before but it came back the other day after a big drive (400KM).

I am happy to reset it again, but I am guessing it will continue to occur and due to it fixing itself after a reset it should be electrical and I think it would be worth checking the ECU for error codes and might be able to narrow it down.

I have had a look but I have not found anything conclusive.

Can someone instruct me how to check for codes (is it a light that flashes a certain number of times and that number corresponds with a particular fault?) and could someone post up a list of the codes and their meanings? Any other help would be great!!

I have also read about a consult cable that connects to your notebook... This could be good, would this be a better option?

If I am able to get all the info it could be an idea to add it to the FAQ sticky.

Thanks guys!!

newkleer has a consult/lcd which displays the error/fault codes and can also reset them ... check it out ...

do you mean that your car does this upon start up ...

i had the same prob i was told to reset the ecu and then turn the car on and let it idle to operating temp ... then hold the revs at 2000 rpm exactly until the car makes this noise bout a min or so ... let the car idle for 30 secs then turn it off ....

leave it to cool turn it back on and see if the prob is still there

its only on a cold start isnt it?

WICKED! Thanks for that!!

I already had this somewhere but didn't think about it!! I have now printed it out so I won't forget to check it first next time!!

The problem happens ALL the time. Not just when cold or first starting.

I can drive solid for an hour and stop at the lights and it will idle at 1500-2000rpm.

This is most anoying when in traffic and you are bumping along at low revs but every time you put your foot on the clutch it jumps up.

I got the same problem

i've checked freakin everything, changed the afm (fixed it for like 1 month) then problem came back

new spark plugs service and everything

afr's and stuff are on the spot, car runs mint

but doesn't idle so well

let me know if you fix it

Cheers
