The HICAS CU controls power steering. It might be unhappy with you disconnecting HICAS solenoids. If that's the case, it's not insurmountable. I have completely removed all HICAS hardware from my car except the CU. Many years prior to that, because of a steering sensor fault, I just disconnected the smaller of the two plugs on the CU. That prevented the steering sensor fault from putting the HICAS into lockout (which wasn't a good place to be, trust me!) and kept the light off the dash. The HICAS CU still appears to be happy with the situation many years since removing the rest of the hardware. So I suggest you try disconnecting that plug first.

But there are other ways that the power steering can die. I once had my oxygen sensor die with a short in the power wire that runs its heating element. That power wire runs in the same loom next to the wire running down to the steering rack, and that wire got damaged by the loom short and I lost assistance. Dead heavy. Real hard to find the problem, but an easy fix once found. I'm sure there are other secret squirrel ways it can die.

You would be advised to start at the assistance solenoid on the rack and see what voltage is present, work backwards from there.

 

bruv dealing with a similar issue at a drift event ive had my 02 sensor fall onto my turbo and practically melt the thing into macaroni what exactly did you do to solve the issue of the burnt up wire for the rack ? my steering is dead heavy almost nonexistent 

please forgive the double quote its my first time posting here any input is hugley appreciated

Hi team

So my R32 has a lock bar in the rear, and recently changed out the power steering pump for a non hicas one.

At first my steering was mildly heavier but still workable. After a short period (hours) i seem to have lost all power steering... 🙃

 

Any ideas what to start looking for?
