R33 GTST Series 1 - New Boss Kit not cancelling Indicators

Hey Guys,

I've recently purchased a new momo steering wheel and an HKB Boss kit (ON-177) which is for HICAS and no airbag as my car does not have any airbags on my R33 GTST Series one (09/1993)

Everything has fitted together perfectly, the black plastic piece at the back of the boss kit fits over the horn plug socket and the Hicas lug attached to the clock spring no problem. My steering column has a white ring with 3 round small lugs that fit into 3 small round holes on the back of the boss kit, and they line up perfectly, which is for cancelling the indicators on wheel turn i believe.

With the stock steering wheel, indicators cancel perfectly, with this new setup they dont. I hear the clicking as the wheel is turned like you normally would hear it, but they just dont cancel. I've fitted and refitted, and checked and rechecked for hours, and nothing looks out of place. i also put the new wheel on, lined everything up, started the car, turned the wheel 90 degrees to the left, then took the steering wheel off and confirmed the white ring and 3 lugs rotated with the wheel exactly where i expected them to be.

I've compared the difference from the back of the original steering wheel to the back of the boss kit, and the only difference i can see is that the holes on the boss kit are about 1mm extra in diameter than the orig. wheel.

Attached are some pics of everything in question, I'm really hoping someone has come across this before as i'm at a loss as to whats causing it.

 

thanks in advance

IIRC there should have been two plastic tabs/poles on your old steering wheel. These are used to cancel the switch when you start turning.

From the looks of your new wheel you're missing them.
(I might be off topic here as I'm referencing 10 year old memories).

I have seen references of this in my research, but i dont think i'm suppose to have them. My stock wheel is fine and turns off the indicators as it should. 

and if they were supposed to be on the old steering wheel, what would these plastics tabs fit into? theres nothing on the steering column except the clock spring and hicas mechanism.

If you could find me a photo of what your talkign about that would help alot.

Thanks for the reply

Ok, sorry. I was misleading you. My recollection (while correct for me) isn't what you need.

The wheels you have need the three little holes there lined up perfectly. I would suggest that they aren't quite lined up exactly. 
To this I would start by measuring the holes on each wheel to make sure that they are exactly the same. 

If they are great, it should then be a matter of just adjusting your boss kit ever so slightly until the new wheel drops into the alignment points. Once it's there it will cancel the indicators for you. It might take a few goes to get it lined up right. You might want to use some tape or a pencil on the top of the wheel to ensure you can line up the top hole correctly.

Thanks, I believe I've done everything you suggested. I used a black marker on the boss kit so i can see where the holes were as i was inserting it. if i noticed they were off slightly, i used a small tool to move the ring into place.

I also measured the diameter of the holes on old wheel and on boss kit and boss kit is 5mm, while old wheel is 4mm, but i dont think this is the cause.

 

And i confirmed that the white ring was rotating with my new wheel and boss kit.

 

Very strange

My limited understanding is those holes must line up. I could be wrong here but if they're a different distance they may not all (3) be lined up when you put the wheel on.

I'm afraid I'm probably no further help though specifically on this one though. Sorry, best of luck. [emoji106]

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
