My personal HICAS diagnostic fault codes, please help

[NRB]

Okay, I've had this problem since I took delivery of my car 12 months ago; I have what can only be described as passive rear steering. When I'm part way through a corner, or when I hit certain bumps in the orad, the car has a tendecy to do some funny sh1t.

In the cornering department, the car straightens up for a second, then tucks back into the cornering line again - something that's particularly scary on the racetrack!

On straights the car tends to "wobble" as if the rears decide to turn of their own accord with no steering input.

Originally my car was fitted with a Nardi steering wheel (with HICAS Boss) and Bilstein suspension lowered onto the bump-stops. Now I've put an original wheel back on (not quite lined up which has had the effect of now lighting up the HICAS light some 10km after my journey's started), and raised the car 20mm and gained sufficient suspension travel.

My HICAS diagnostic codes when I had the aftermarket wheel on were:

no fault from

1. RH solenoid output

2. LH solenoid output

3. Fail-safe valve output

4. Power steering solenoid output

but faults from:

5. Vehicle speed signal

6. Steering angle signal

7. Steering angle neutral signal

8. Clutch signal

9. Neutral signal

Of further note is that the car has definitely had the speed cut removed, and has some sort of ATTESSA override switch, which with the press of a button I can put the car in RWD (for burnouts I guess).

Any ideas what I should do? I've got my car booked with Nissan next week, but if I can fix myself I'de prefer it

Cheers,

Nick

When your in Diagnostic mode do you turn the wheel from left to right, take the hand brake off and put it back on and move the car back and foward about 1 to 2 meters?

When I did that test I did not... didn't think about that!

Try that when you next get the chance and that should get rid of them error codes.

Will do, thanks. Still doesn't solve the dangerous handling characteristics though!

I think you will find that therein lies the problem. Get the steering wheel lined up properly on the sensor, and get a wheel alignment with the steering wheel in the centred position.
