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.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.

      @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html

      These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.

      The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.

      It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
