Ok all,

I was at the track last Friday and lost my power stearing at the end of a pass and the HICAS light came on. When I got home I

replaced the power stearing pump and also replaced the HICAS

switch behind the stearing wheel. My question is how do I get my

power stearing back????

It is still not returned and I'm about to replace the sensor contected to the HICAS pump on the RH side of the engine bay next to the oil filter. I had a shop do a diagnostic on it and they said that the stearing wheel switch was bad so I replaced it but

their is no differance. Still no power stearing and damn light is still on!!!

HELP..............SOS....

The most common cause of P/S loss and HICAS light on is a minor loss of P/S fluid. Topping up the fluid will usually cure it. (A 'search' through these forums would have found this)

But since you have gone overboard with the fix, are you sure there's no air trapped in the P/S system?

Ericherm1, could you email me and let me know how you go? I've had a similar problem with my car. The HICAS light comes on after a while while driving.

I've only had my car on the road for about a month (fresh import) and I'd like to sort it out.

Thanks Rob.

The fluid level was the first thing I checked and double checked and the level and all is good.

How would I go about purging or bleeding my power stearing system, if their is an air bubble?

I'm only down to 3 more options left as I see it,

Replace the cut off valve attached to the HICAS sylinoid,

Replace both left & right sylinoid,

Replace the HICAS computer in the rear deck.

???

Thanks,

Eric

Oh yeah, (off subject) my car ran low 11's that night too....hehe

RAB....... thats becuase the computer has not received any input from the steering wheel for a little while. Its not a problem when that happens. Could also be that you have a aftermarket wheel on and not got the proper boss kit. Get the right boss kit and prob will be fixed.

Ericherm is it possible that you need to get the errors cleared from the ECU? I have the exact same problem and have been chasing my tail around forever trying to fix it. Please let me know how you go.

ok.... let me say this:

I already have the correct boss kit, and I know where all the parts are on the car, to include the power stearing resivor, and its filled to the proper capasity.

Like I said before I already replaced the rotation sensor in the stearing column, and the power stearing pump itself. But I still have the problem with no power stearing. Parking is such a pain with no power stearing!

Sorry to sound firm but i'm very frustrated right now,

oh and ..lol

Well I think I am going to just buy a HICAS Cancel Kit and lock

the rear end and then just unplug the HICAS Computer.

I tried unpluging the HICAS computer yesturday and I got my power stearing back. But when I pluged it back in it was gone

again.

Anyhow my mechanic did the diag test and found out that the HICAS computer is in safe mode, and we cannot figure out how to get it out.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
