HICAS Light

[red coupe89]

hey everyonce, followed a few different DIY to decode the HICAS light on my 91 Z32 but to no avail. from the moment I turn my car on the light is red the entire time. some times on an on ramp the car will turn harder for a moment while the wheel is at the same position threw the cornor. is there anything in particular I need to look for or if there is a better DIY for decoding the light.

any help would be great,
thanks!!!

Have you checked your power steering fluid?

yea fluid is at the full line when running.

Check it when the car isn't running

^ what he said. Shut the car off and let it sit for 5-10 minutes (better to do it after sitting over night). Check level, if low, fill with ATF (not PS fluid). Start and check light. If that doesn't work, you'll need to do the HICAS diagnostics.

yep its at the full level when bone cold as well. i tried to get it to enter diag mode and cant do it, ive found 2 different ways as well, neither worked.

thanks
