Hicas Light + No Power Steer

[Odium]

Hi Guys,

R33 GTST S2 w/ A-LSD

Full exhaust (High Flow 100 cell Cat was installed 2 days before the problem first appeared)

R34 SMIC (Installed last weekend)

Last week (Thursday) I went and got petrol at the servo and when I turned my car back on, the HICAS Light was on and the steering was very heavy (still drivable though).

I turned the car off, waited 10 seconds and turned it back on,

Light was still on, Steering still heavy.

I drove it home (2km) then turned it off, waited 30 seconds. Still bad.

I went inside and got my Consult Cable / ECUTalk Display and went back outside to plug it in 30 minutes later.

When I started it up it was working perfectally again, No Light, Power Steering working.

ECUTalk displayed No Fault codes on this or previous starts.

All was fine for a week, did 350km on it and then last night went to get Petrol.

Same Servo, after the same 40 minutes of peakhour.

Filled up my tank with another 45L of V-Power and started it up. Once again, Hicas Light on and no Power Steering. No Fault Codes.

Drove it home and just before I turned into my driveway (2km) it magically fixed itself and the Hicas light went off and power steering returned.

Random Questions:

Any ideas what I should check or what might be causing this?

Is Fuel in any way related to HICAS?

Is HICAS in any way related to Power Steering?

Maybe a sudden temperature difference when I add in 45L of cold fuel to the warm car?

Anyone else had this issue?

Heading up to DECA in 3 weeks but don't want to be trashing around a car with HICAS or Steering issues, obviously.

Thoughts?

Cheers,

Simon

Hmmmmmm....

I've been reading through all the other Hicas related threads on here and a lot of them seem to have this problem.

There were mentions of bad battery earth (mine does need replacing badly, I had to remove it a few months ago for a little bit to get a new battery in, and ever since then my stereo has a bad earth whine to it...)

I will try HICAS Diagnostics as well and report back.

Otherwise, looks like it might be time for a lock bar

I've had the same issue for a long time now, and never been able to resolve it. If you resolve it. Plz let me know ;')
