Hicas And Steering.

[Jdfnq]

If the steering angle is incorrect, you will get an error code telling you that.

I have a stock wheel on my series II R33. I do get an error code telling me that my speed sensor is not present. I have done this diag on several other R33's with great sucess....

I don't always get the car to wiggle it's bum ( it does this the first 5 or 6 times that you put it into diag mode) as I believe that you may need to reset the ECU after several attempts....... As everytime I try to put it into diag mode now for the HICAS, it just shows up the error code (21 in my instance) pretty much straight away....

When I get a chance, I will re-set the ECU and see if that makes any difference

I've found out with one sensor that ECU doesn't always detect a slight fluctuation in voltage.

For example the voltage difference was roughly 0.02v from recommended voltage

for that sensor. Basically wasn't enough for ECU to detect sensor is faulty and

produce an error code. ECU thought everything was working properly.

Found this problem sensor by checking via volt meter at the sensors.

That's interesting about the 5-6 times.

Make sure the speed signal wire isnt cut also, HICAS uses it. Use your a/m ECU to get rid of the speed cut

If anyone needs a hicas computer i have one...

and other random hiscas stuff..

hicas is teh pooh

Question is.. Can I run the standard computer and start the car to run the test with.

non standard afm. Non standard injectors. I think not. But please correct me if im wrong.

If you have a PFC it should work fine, the PFC piggybacks the ECU and feeds it false info to trick into doing the right thing.

you mean it piggybacks the hicas ecu? or do u mean the PFC mimics the ecu?

[R33S2]

it piggybacks it meaning it intercepts the engine signals and atlers them so the ecu produces the right responses.

[SilverECR33]

i know it theoretically it should work but its not. Me and joe tried at length on the phone to get it working but no go, also i have messaged paulr33 on this matter, but no one has confirmed it works with the pfc yet. Have you got it working yet?

[SilverECR33]

pfc is a standalone ecu, the stock ecu is sitting on my work bench

[R33S2]

well I fu(ked that up grandly then. I have sinuitis.

all good m8 . The problem seems to come and go, its damn strange. and wish i could sort it out

Still no love Dale????

I re-set my ECU and the rear tyres have gone back to wiggling during the HICAS diagnostics.....

[SilverECR33]

nah, still no love .

Its interesting now the problem has shown another form of itself.

Last night, after i started it, the hicas came on, Stayed on, But the powersteering was still working this time . but the ACC throttle blip still didnt work.

good call

lol ive GOTTa get one too..

[shanef]

seriously i dont understand why u guys dont just lock the f**king thing up. beats tearing ur hair out trying to find an electronic issue amongst all the crap.

but thats just me *shrugs*

im surprised you dont have one already drift-man

(its the first thing i did to my 32 when i got it)

lol zennon i dnt have one buddy.. my 180 dont have hicas eww..

suspension wise i got rear traction rods. rear under brace strut brace F+R and Teins all round on 1.5neg

will have steering spacer no more rubber one and castor rods front and front underbace. oh and the 2way diff helps

the other 180sx has hicas and be getting a lock bar soon.

but ill prob pull the engine out and doin all pro

when i do the RB25 unless i get bored one arvo..

oh and zennon first thing i did when i got my 180sx the very arvo was raise the bonnet and put a nardi on.

It really helps turn in, and stability on sweeping corners. I am not using the car for drifting, so Id like to continue to use it. Really comes down to driver preference, And Id like to see how far I can excel with the Hicas. Ive driven Non hicas cars my whole life, And Im liking the technology.

Please dont whore this thread. Lets keep discussions on track.
