Hello, my Hicas problem rose again. Now, I will search and finally find the problem but....I was thinking about a solution that might suit several people.

Is there anybody who knows how the Hicas and/or non-hicas PS-ECU deals with the different signals? I mean, both systems have parking-brake, brake, clutch, inibitor-switch, steering-angle, speed-sensor attached to it. I wonder why? Speedsensor I can understand but not the others.

So, suppose I do delete the hicas-system as many others did, what do I do with the ecu? If I take it out I do loose the power-steering wich I don't want. Is there some sort of piggybag solution?

Is there anybody who ever tried to make a circuit-bord that convert the pulses comming from the speed sensor into voltage that could be connected to the ps-valve? I mean, this could be the solution to take out the ps/hicas-ecu and still profit from the speed-variable power-steering.

I worked in electronics for more then 15 years and have connection and people who could try to make some sort of piggybag for this but I have to know if it's worth it and if some sort of system doesn't already exists, I don't want to try to re-invent the wheel.

 

For the language-specialists, english is not my native language and I don't have the ability to edit so sorry if there are mistakes in my tekst. I can do it in dutch of french, there will be less mistakes :clown:

If you delete the Hicas. All you do is unplug one of the two connectors into the Hicas ecu. It's obvious which one as unplugging the right one will turn off the Hicas light
