Re: Air Bag Warning Light - 156
Have got the same problem onmy 1.8 TS 2001
Considering the AlfaDiag to reset the LED, but am little confused about the disconnection business of the battery. Am I understanding the procedure to be disconnect battery, leave it for 15 mins or so, jiggle the underseat yellow wires, reonnect the batery, plug in the alfadiag on laptop and cable, then reset the light.
OR, is it to be done while the battery is still off. And if so, does the ECU system draw its power then from the laptop.
Having never done this before, we really need to know what is the correct procedure. My nearest Alfa dealer is 40 miles away, and its a day out to get there and back from here, so it may be a long term investment to purchase the alfadiag software, and try to resolve as many of these problems as when they occur.
Thnaks folks, Andy
