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
