4wd Probs

[GimpyDammit]

Just had my car tuned today on a 2 wheel dyno, and now the 4wd light comes on.

Tuner pulled the fuse, so I check it and its ok.

Ecu is flashing 21 times.

Seemed ok on the way home, light came on and i pulled over, turned the car off and on again and it didn't come back on. Went out after and let the car sit for a few hours and when i started it again, light comes on and stays on. Tried pulling the fuse and pulling it back in, light goes off then comes on again, tried switching car off while moving and back on again, same thing light goes away and comes back.

Does the Atessa ecu store codes? Do you have to erase them?

Is it the Atessa ecu flashing or the Main ecu.

If it is the main then you may find it is a error witht the abs sensors due to ony the rear wheels going when on the dyo....

or

Could also be the same for the Atessa ecu...

Try disconnecting the battery then holding ur foot on the break for 30 sec to drain all power reconnect battery and see how you go.

I will dig up the Fault codes for you. Just check the flash sequence again.

Its the ecu in the boot.

Code 21

The only thing i can think of was when the tuner looked over the car he noticed a plug that was unplugged, and he plugged that back in, that and he moved the throttle postion sensor a little.

If i do the batterty discharge thing, will i have to re-set my boost controller?

Sounds like your TPS is faulty> I had this on my R33 GTR. Same thing. The light will come on shortly after I start the car. If I Kept driving it wont come on.

If I stopped and idle abit . Boom. on. Changed the TPS after hooking up the NIssan consult.

What sort of boost controller... I would say it would't not lose its settings.... If it did would be no good when you get flat battery....

Someone correct me if i am wrong..

If it comes back on after this then yea the sensor is probley dead...
