4Wd Light Has Come On!

[james32gtr]

Iv just brought a 32 gtr, when I test drove it no light was on, took it home have driven for 2 hours on a freeway and suddenly 4wd light has come on any ideas what the problem could be please??

[Sinista32]

Firstly use the search function. There is heaps of info on here and you will get more help from others if you üse search first.

It could be many things from the fluid level, blown fuses, loose screw in the Attessa ECU even, dirty sensors in the wheel hubs, G sensor.

Is the ABS light on as well ?

Check the 4wd fuses in the fuse panel in the cabin and the fuse in the engine bay.

Check the fluid in the reservoir in the boot on the drivers side behind the trim panel (with ignition on)

- then get back

and welcome to GTR ownership

start of many things to fix

No abs light on, checked the attesa box in the boot had 9 flashes, abs actuator relay or circuit. But the ABS has been removed :s

Well, there you go.

[james32gtr]

I know it seems like that would be the reason but there must be more to it, as it wasn't on when I brought it, drove it for an hour, then another 30 mins later came on. I'm a bit confused as I'm not so technically advanced with engines!

[niZmO_Man]

Does it have an aftermarket steering wheel?

[blind_elk]

That's for HICAS!

Maybe the relay is acting up after a while - try a new one.

[Sinista32]

The unit is reporting correctly (9. abs actuator relay or circuit) Yours has been removed so that s norm

Call the owner or visit him and ask what he has done. Doesn't sound like it has been bypassed in any way as its working as it should (Error Msg)

Maybe it is possible to bypass so the error is not reported.

Your solution may be to remove the globe from the cluster if it annoys you.

Yes has a mono race steering wheel.

Got in the car this morning to take it for a drive and the light wasn't on I think I'll see how it goes next few days. I don't think it's anything to worry about. Thanks for your help.

[niZmO_Man]

Oh yeah oops, sorry, my question was for HICAS, my bad.

[portaz]

Wouldn't the abs being removed cause all sorts of issues with the 4 wd system ? How. Much has been removed? Just the unit or all the sensors as well?

Nizmoman asked the obvious question, "Does it have an aftermarket steering wheel?"

Now you must do some test driving NOT on the freeway, just normal suburban stuff that involves corners.

If your light stays off after the 20 or 30 minutes, the steering wheel boss is your problem.

A lot of aftermarket wheel kits don't locate the sensor correctly in the boss.

So the car thinks it's turning a huge circle when it's actually going straight ahead.

If you do suburban driving with corners etc, the HICAS ecu won't care but on a freeway with lots of straight ahead driving, eventually the HICAS ecu will throw a fault. (I found it to be around 20 minutes of straight steering)

Key on/off and you're usually you're good for another 20 or so minutes before the light comes on again.

However if your light returned even in suburban driving, you'll have to keep digging.

[Sinista32]

Hicas would put Hicas light on (if globe in cluster) and would be associated to 4WS and steering wheel as above, lock bar?.

but suppose could be an issue too...I'm not sure how 4ws and 4wd are connected.

First post mentioned 4WD light is on.

This definitely involves ABS, Brake system, Attessa ECU, Resevoir, Speed sensors, Pump, Solenoids and the G sensor. (and Attessas electrics)

[GTSBoy]

I don't think the ATTESSA system monitors the steering angle sensor.

[james32gtr]

So the guy I brought it off got back to me, says he never realised it :s but what ever!

He also informed me that it has a tomei hicas lock kit on it so maybe that has something to do with it, I don't even know what that is so will research it and see of it could be the problem.

Maybe I'll also get a new boss kit just to reduce the source of problems to choose from.

[james32gtr]

This message was meant for my other thread juddering and jumping.

[portaz]

If it has tomei lick kit there will be a little box with tomei written on it attached to hicas ecu

[james32gtr]

Yeah it has the little box got it
