I know there is probably more HICAS related threads in here than anything else but I think I have come up with a new problem.

My HICAS light comes on only at certain times. It will come on only if I am sitting steady on a decent speed (around 100km/hr or so) it will come on within half an hour of coasting at this speed (highway).

I could drive around non stop all day at 50/60km and it would never happen.

Anyone ever experienced this?

Cheers...

No you haven't :) It only activates above 50-60 i believe. Somethings wrong and its deciding to come on then. Hit the search button like a naughty nine year old. PS fluid level, after market s.wheel?

Tried HICAS diagnostic mode? There is a sticky post under DIY which will explain how to get in there.

In my case, I couldn't get into the diags because the steering sensor was broken - and the diagnostic process needs a functional steering sensor (grr). Took the steering column apart, cleaned everything, popped the loose parts back together .. and I can access the diags now.

As an added bonus, my HICAS light no longer comes on randomly :)

    • Just to be clear, there were no lights or codes when the hiccups were occurring. Also nothing noticeable in the cars' braking. It brakes fine and the dash is clear. I only made the connection when it did throw a code and suddenly, despite the lights, it felt great again. 
    • Yeah they are sliders and this was in my head before I worked out it was the speed sensor.
    • Ok so we have a smoking gun.  A few weeks ago I had to replace a speed sensor that I'd fit incorrectly. I replaced the sensor and everything was fine with no lights or codes thrown any longer.  When I was doing some more bedding in yesterday I got ABS and traction control lights again and, considering when this happens those things are disabled, the pedal went back to normal with smooth braking and no hiccups.  The codes thrown are for the same speed sensor that I replaced. When I looked at the sensor I took out it looks like the tip of the sensor is damaged. So whatever happened to it, perhaps it has damaged the magnetic ring on the bearing (that I only replaced the other week). I'll get my boroscope in the hole where the sensor goes and see if there is any damage in there. Hopefully just the tip of the sensor is in there and the bearing is fine. 🤞🏻  It's worth noting also that the pedal hiccup happens more often and for longer periods now and totally goes away when the codes are thrown again which happens usually after 5 or so minutes of driving. Love all your help here as usual guys, thanks!
