My air bag light has come on, and I had it plugged into a diagnostics machine at a garage, believe it was a snap on, it came up with could not communicate in regards to the air bag, it could communicate in regards to the engine management etc, any suggestions on what the problem could be would be useful. It's a 2010 skoda fabia 

 

 

 

 

The snap on tool used would have to be able to talk to the airbag ECU, ie it must have the software in it, so it's not neccessarily an error / fault with the vehicle.

 

Talking to Engine management could just mean standard ODB protocols which all vehicles will have, its vehicle specific stuff that would prove the capability of the diagnostic machine.

Ideally you need a VW or AUdi or Skoda specialist to plug in and check or someone local with VCDS

 

If you airbag light just came on, then worth a check under BOTH front seats and look for wiring to a yellow plug, ensure they are both connected properly. (DO NOT DISCONNECT WITH BATTERY CONNECTED / IGNITION ON) as this can register a fault as well.

This is what came up when I used a vcds diagnostic tool 

 

01578 - Airbag Deactivation Warning Lamp; Passenger Side (K145) 

 

36-10 - Open Circuit - Intermittent

 

 

 

 

 

 

So from the code it "seems" it means the passenger deactivation lamp is faulty.

 

Do you get any light when you deactivate via the key switch on the side of the glove box (assuming you have one) ??

 

PS maybe worth trying the key switch a few times.

Some one has cleared the code and so far it hasn't reappeared at the moment
