M35 Airbag Woes

Hi all,

Been a while since I've posted on SAU.

Recently picked up a beautiful example of an M35, and it has been flawless aside from this one minor issue.

It's intermittently throwing an airbag code and flashing the light on the dash. It first happened the day I bought it home and the wife jumped in the car with me. We had been to a couple of places that morning already, and it wasn't until we were halfway between one place and another that the light came on.

I took the car to work and plugged it in to read and clear the code.
All was then fine until Friday just gone, where I had 2 passengers in the car, and I had been out and about with them for a couple of hours. It was only on the way home with the same people sitting in the same seats that the light started flashing again.

Back to work today, and I plugged it in to read the code this time. Once again, it's the same code..

Both times the code is appearing under DTC history, so it's only active when there's someone sitting there. I'm assuming it's something to do with the passenger seat at the front.
Ideally, I'd like to properly fix this, but failing that, I'm willing to do the resistor trick to sort it out.

Can anyone point me in the right direction of the wiring/plug/sensor that is causing this?

Cheers,
Ben

I have the same thing, a different code. I see your post on facebook, it has to be some plug/contact needs a good cleaning, our best bet is to pull the seat out and check all the wiring/connection, will dig into it one day.

I don't believe this will effect the deployment of the airbag if needed.

If the airbag lamp is lit it's likely not going to deploy. Most likely it's the switch under the seat that is faulty, but check the plugs too. Might be best to try and bypass it like I did years ago when I fitted Bride seats.

How do you bypass it Scotty?

no problem.
theres only 4x14mm bolts holding seat in.

under the seat there is a yellow plug ( theres only 1)
unplug and wire a 2.2 ohm resistor in ( theres only 2 contacts so you cant f&% it up)

personally I disconnected the battery and waited a little. I'm afraid of setting the ram off.
also I tested before bolting the seat back down. otherwise its stupid easy.

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
