Airbag light flashing...diagnostic mode.

OK, I have always had a SAAS/Momo wheel.  The car came with a very plain Nardi wheel ( I never ever had the original wheel) which I sold, the SAAS wheel has been on ever since - talking about 20 years.  Anyway recently my 'go to' guy for rego finally figured out that I should have an airbag wheel ('98 Gtst).  Although I got a pink slip I also knew the SASS wheels days were numbered.  Since I had 2 standard wheels (bought for such a day), it wasn't a problem.  I actually had one wheel refurbished with leather, alcatrana and CF and fitted it.  Plugged in the airbag and got the dreaded flashing airbag light.  Tried the other wheel and same result.

The flashing is the usual quick flash, I thought easily solved with the 7 interior light button trick, but it didn't work.  What did happen was it went into diagnostic mode and I got one long flash then two quick flashes, repeated and repeatedly.   Every time I tried the 7 interior light trick it went to this 1 long, 2 short flashes.  I disconnected the battery and bled the system (lights on etc) but no combination worked.  Then I put my 0.7v resistor adaptor back in had to do the 7 interior light trick and problem solved - sort of.

What I want to know is what this pattern is indicating?  If I knew this I could do something to fix it.....otherwise its off to see an auto sparkie and round here they have zip zilch zero Skyline experience and probably diagnostic knowledge, software, or tools.

PS I also tried a few other tricks I found on the internet, such as turning the ignition off before the first flash 3 times etc but nothing worked.

TLDR....my airbag light is flashing one long and two short flashes......what does this mean?

So, I don't know the R33 GTST flashes.

However, I had as similar issue for the drivers side seat airbag in the cima, ultimately I unplugged it and put an appropriately sized resistor between the 2 wires on the car side to turn the light out. I can't remember the resistor size and it varies between models, but I just used a variable resistor (pot) to find the right one to put in.  That would get you an airbag steering wheel but no airbag warning light

Yeah Duncan, that's what I have now as a temporary fix.

But ideally would like to eventually have a functioning airbag setup....hence my question.  But if i don't get an answer then I'll be taking the car to an auto sparkie with no idea of the diagnostic message [one long and two short flashes].

I thought if I could find out what the flash sequence meant then I could at least have something to check when I take it in.

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      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.
