Resetting "Infl rest" airbag light on 90 vette

[malc350]

Can anyone remind me how to reset the airbag light on my 90? I did it once ages ago when I sufferred from the usual "dirty" sensors on the frame rails.

This time I get a code 42 which indicates an open warning lamp circuit which I think could be down to me removing the DIC and turning the key (stupid). I'm presuming all I need to do is reset the light?

I know the procedure involves shorting contact K on the ALDL on the seat rail until I only get a code 12 but I can't remember for how long and for how many times? I've tried it several times but I think the procedure has to be EXACTLY right.

Thanks in advance, Malc.

Here are the instructions straight from G.M.
1. Turn ignition off
2. Ground ALDL Terminal K (this is the lower row, 3rd from the right).
3. Turn ignition on
4. Wait for fault codes to begin flashing (approx 5 seconds). When the codes begin flashing, unground ALDL terminal K for 3 seconds + or - 1/2 second.
5. After ungrounding ALDL K as described in step 3 above, ground it again for 3 seconds + or - 1/2 second.
6. Unground ALDL K and wait 10 seconds. Before turning the ignition OFF, verify that code 12 is the only code being flased (this is the seatbelt/air bag light flashing). If not, codes have not been properly cleared. Repeat from step one if codes not cleared until the codes clear.


When I do this, I put a jumper wire on K and used some aligator clips to ground it to the driver door hing (cuz I have the door open the whole time). You can ground, unground th aligator clip to the jumper to clear the code.¨


It takes about 20 tries to get the light to reset.
