car swings side to side over bumps

[Drivebai]

Hey all,

I got a problem with my R33, everytime i go over a bump or if the road is alittle bit rough, the car seems to sway side to side like i'm going bush bashing or something, the car just feels really unstable sometimes at the slightest bump.

The car was fine until i got it back from the tuners when i had the SAFC tuned on the Dyno, i dont know if something is broken or loose.. any help would be appreciated thanks

Damn that sounds really suss... get out and count the wheels, there should be 4 of them

Seriously, I would take it somewhere for a quick look, maybe one of

those places that offer a free 16pt safety check. get under the hoist with em and have a look.

its prob just the hicas working

ive felt the same feeling sometimes

its just a tiny wobble that u can only feel through the steering wheel

Good thinking K

Actually, i remember once with my car on a dyno the hicas light was coming on. after a few goes of the operator getting in and

out of the drivers seat, the steering had been turned a considerable amount. hicas kicks in at approx 80+kmh and tries to turn the rear steering, which of coarse it cant do cause the rear wheels are wedged into the rollers.

dont know if this could break anything, but worth consideration.

yeah this does sounds abit suss now but this is happening at low speeds as well.. its like the death wobbles...

hey guys!!

i seem to have the same problems as Drivebai is experiencing and did a hicas diagnostic on the car just before..

the codes i recieved was

3 long flashes..........followed by 2 short flashes..........and then 1 extra long flash

does anyone know how to read these codes properly??? my guess is that its either saying

first 2 long flashes means there is a fault

2nd long flash is the first didgit = 1

2 shorts flashes = 2

meaning:fault no#12 - Hicas motor power supply not present

or

3 long flashes = 3

2 short = 2

meaning: fault no#32 - engine signal not present???? (i have no idea im lost)

could someone much more cluey give me a second opinion on this !!

CHEERS!!!!

I have HICAS error codes 22 and 32, and I've got permanently heavy steering, but no HICAS light on ever. Anyone know how to fix this?

EDIT: My car also has the sideways movement over bumps too. It's really annoying. Even driving on a slightly bumpy road gives my arms a workout trying to keep it steady.

Mic33r - did you check out that site i posted earlier..

yeah my car doesnt swing that bad.. it just kinda wobbles abit and is very annoying.. also the other nite i gave it a squirt of the line and the rear was bouncing up and donw while losing traction where as before the tyres would just screech...

also does that if i go round corners really fast.. i rang up justjap and they think it more than likey the shocks or a loose bush somewhere i will have to test out the hicas diagnostic thing as well.. although my hicas light doesnt come on either...

let us know if you find a solution
