Heavy Steering And Hicas Light

[ocousins]

A couple of weeks ago my Hicas light of my R32 GTR came on. I checked the fluid, found it low and filled it. The light went out and I have had two problem free weeks. Today I pulled the coil cover off to inpect my spark plugs, spark harness ground, and ignitor ground. During this time I disconnected the neg battery terminal.

When I was finished, I put it all back together, connected the battery and left the car idling for about 10 mins. When I got in it, I noticed the HIcas light on again, and the steering very heavy, almost as heavy as when the engine isn't even turning. I checked the fluid and its fine, did the air bleed procedure (full left and right turns with ignition off, then with engine running) and the light remains, as does the heavy steering.

What could I have done by disconnecting the battery? Or how about disconnecting spark harness and ignitor? That's all that I touched and it's pooched now. Will try the Hicas diagnostic next, but not sure if the APEXI ECu affects that.

Is there a fuse that may have blown by a arc'ing battery ground as I attached it? There was a pretty good spark because I had the trunk lid open when I connected it and the trunk light pulled a decent current

Thanks!

Well this is embarrasing, but apparently Hicas does have a fuse, found on in the inside box. The arc'ing battery terminal as I reattached battery must have fried it. A new fuse fixed the issue.

I found it by checking each and every fuse as I couldnt determine the obvious fuse from the translated diagram

where abouts is this "hicas" fuse?
