Airbag Light

Hey there guys,

I have an R33 GTS S2 standard ECU. Since I bought the car it's had an aftermarket (non-airbag) steering wheel on the car, though recently the battery went flat in the car and now the airbag light is flashing in my eyes and is rather annoying.

Does anyone know of a way to shut this down? It's obvious there is a way, seeing though for the past 8 months it wasn't flashing. Also, just out of curiousity, does the factory ecu have fuel maps and such that people refer to when discussing aftermarket ecu's and or do you think there is any programming I could have perhaps lost in my ecu since the battery has died, and if so is there any software available to see what is happening in there???

Any help or info would be great...

Cheers !!!

Thats an interesting problem you have there dude. you say you have a r33 gts s2 ecu? first off i would be getting my hands on nissans consult scan tool to pull some codes out of it and see what it is saying. considering the fact that it is now missing the return signal from the steering wheel mounted airbag unit will definately be the reason for the light. my first question would be why has the s/wheel been replaced with a

non airbage unit and how did they turn the light off? i know this isnt alot of help but i'd be a bit worried about because with the light on remember the passenger side airbag will NOT deploy in an accident and to be honest with out the seering wheel there i doubt whether it would go off even with the light off.

as for the ecu, yes it has fuel maps and there is a few resets u can do to ensure good idle such as a Keep Alive Memory relearn and an idle reset,

I'm not sure how the airbag light was disabled... I bought the car with the aftermarket wheel fitted from an importer, so it was complienced with the steering wheel fitted. I have no idea how the setup was, though the light would come on when first starting the car (as you would expect, with the engine light etc) thought after 1 or 2 seconds of the car running, the light would disappear, it was as if they had trick the computer to thinking there air bar was there.

As for the ECU settings... you said there is something like a self learn proceedure? How do I initiate that and whats the story - is there a website or a topic in SAU that gives instuctions... the car is running fine atm, so should I have concerns in reseting the ECU ??? Has anyone done this - should I just let it be???

Cheers...

by user ylwgtr2

he posted up a way to clear the self diag. try this and you should speak with a nissan dealer about the problem, as it could be dangerous (ie: airbags may be disabled)

Common issue when the airbag is disconnected from the power supply. To remove the light you need to reset the signal to the ECU, i think its via resetting the ECU. Talk to NISSAN about who has diag tools.

In the meantime your airbag doesnt work so drive safely

i would dare say that the light was turned off with a resistor or a simulator placed into the wiring at the steering wheel connection to the airbag harness. i would say that with the new batery connected the voltage/resistance seen at the control unit has slipped outside of preset parameters. how and why i dont know....................... :wave:

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
