So i am seriously thinking bout removing the hicas in my R33 GTR.
Between 60km/h and 120km/h, when driving in a straight line. The rear wheels will kick left and right real quick. Sometimes it kickes right then left. It feels as though its doing a quick diagnostic. I have seen the wheels move left and right in diagnostic mode on my car, and it would pretty much be the same, but at speed.
When running diagnostics, it has shown no response from steering wheel sensor. So i may just replace the sensor and see what happens, although i dont think it will fix the real problem.
Now it was only last week I realised these problems started around the time I installed a sub in the boot. I always drive with the stereo at a decent level. I didnt put 2 and 2 together until i was on the highway in the wet, and the back end was kicking out every couple of seconds. This is the worst feeling that i have ever had in a car. I pulled over, turned down the stereo, and then took off trying different speeds to see if that effected anything.
No kicking, no bucking, no nothing. The car went like a dream at any speed. Thinking the worst was over, i cranked the stereo back up and almost instantly, the back end kicked again. I also got to work out what songs made the hicas angrier, LOL.
It will take a while to work out exactly what is wrong with mine, and being cost effective, the lockout bar sounds like the better option.
Any opinions?? HICAS light doesnt come on at all, unless i run a diagnostic, which ran perfectly.(apart from the no response from steering angle sensor).
And yes, i know the easiest fix is to take the sub out!! But for safety sake, I would love to fix it properly.
