I own a 1991 Jap import tt. Ive not had it long so dont know a great deal about the car. I am aware however about the hicas 4 wheel steering system. My rear wheels are fixed and do not turn. (except to roll before the sarc). I have checked fuse this is ok. On the solenoid next to the hicas resevoir I noticed a plug had been disconnected and ty wrapped out of the way. Thinking this was a quick fix I promptly reconnected and monitored rear wheels as i turned the steering wheel. They still do not turn!!! Res level seems good. Any suggestions???

HICAS doesn't work when standing still unless it's in diagnostic mode.

Well that would explain a lot! What about indication? I get no light on the dash with or without this plug connected!

it's poss that someone has disconected the hi-cas and removed the bulb in the dash. when you disconnect the brown plug near the powerstreeing pot this fools the car into thinking that it is low on fluid and turns off the hi-cas system. alot of people do this.

i wouldnt think you would notice it anyway. doesnt it turn only half a degree or sommat?

if HICAS is working correctly and in diag mode you can see it very clearly.

Quality image. I would of thought 1degree's was far less visible. Thats cool.

looks like i stand corrected. i agree with Legrath tho - perhaps theyre really the front wheels ;) :D

only joking - odd the bodywork and reflection seem to move tho :confused:

How do you get it into diagnostics mode then chaps???
