Oil Gauge + 4wd Light

[icydude]

Well i just replaced my dead alternator and now it seems i have another problem.

while i was driving through the city my 4wd light kept coming on so everytime i had to stop andthe light was on i would start the ar again andthe light would take about 3-5 min to come on.

Now the car is sitting in my driveway and the 4wd light comes on right away after starting.

I have checked the fuses and they are all ok.

The atessa computer is giving me code 18.

To go along with this problem i feel that my dash lights are dimmer than they once were.

The worst of it is my oil pressure guage in my cluster is reading 2kg/cm higher than it normaly does. 4kg/cm on idle, 7 at 4000 rpm.

Does anyone know what i might have goign wrong?

[icydude]

any ideas?

Error code 18 is ETS pressure switch circuit.

Its very common to get the 4wd light when you have electrical problems.

Put a multimeter across the batter terminals when the car is running, do you get 13.8volts?

[icydude]

the apexi pfc reads 13.7 - 14.3

could i possibly have a faulty ground?

[Duncan]

perhaps, and there are some relays under the rear boot trim as well. do you get 13.8 at the attesa computer as well?

I will check around in the rear.

I do hear a relay click everyonce and a while mounted by the passenger rear tail light.

Ok i madea discovery today and i would like to get some guaidance.

i noted before that i felt the lights were dimmer on the dash.

well i measuered the voltage at the cigarette lighter and it was 12.9 and the fuel pump was 13.1.

The battery was 14.0 and the ecu said 14.0

Now somewhere along the way i have a bad connection i figure or a bad ground.

Any idea's on what my problems could be now since i know its electrical?

[icydude]

one last try,

when i turn my lights on the voltage on the pfc commander drops .4 volts lower then when they were off.

any ideas

well the guys at the alternator shop said to check my engine to body ground.

im pretty sure i stripped it checking things.

damn.

Any luck with these problems? I have an R32 GTR and my problems are almost exactly the same as yours. 4WD light comes on after 30 mins of driving, every now and then i get a click (relay?) from the rear of the car and my oil pressure guage displays all sorts of differant readings...

HELP!

I get that same problem too but the clicking in a constant one but in intervals, the 4wd light doesnt come on tho...anyone else had the abs light come on when it has been a really cold day?

re the 4wd light coming on after 30 min, does the HICAS light come on as well? And if not, do you see the HICAS light come on when you first turn the ignition on before starting?

When i first got the car the hicas light would come on after 30 mins... then it changed to the 4wd light but the hicas light ceased to come on after 30 mins. Im not sure if the hicas light comes on when i first turn the ignition, Ill check tonight.

Thanks for replying.

Yes the 4wd and the hicas light come on when i turn the ignition on.

Any ideas?

My problem was a loose ground from the engine to the body....i loosened it by accident while putting the alternator on.

Hi,

Ive left my above problem unresolved for quite some time now as i havent driven the car for many months however i have now i would like to solve it as now the problem has become a lot more serious. Hoping someone can assist.

The problem just to recap is as follows ('89 R32 GTR)

4wd light comes on after around 30-40 mins of driving, it doesnt always happen, but most of the times that i drive for this amount of time it does come on and stays on until i turn the car off and turn it back on.

Prior to a few days ago it seemed as if the problem was just with the light coming on but not a problem with the 4wd itself, ie the 4wd was fully functional(not sure if it was working when the light came on or not).

In the last few days the problem has become worse. The light still comes on (most of the time) but now i have no 4wd at all regardless of if the light is illuminated or not!

My mechanical knowledge is poor at best so apologies if i dont supply enough info.

search the forums for a topic on bleeding the attessa system if you are still have the problem.

just sounds like you have an air bubble or not enough fluid.
