Hi,

Why my airbag light is on?

susan

[Jimbob]

A good question,

You will need to get it connected up to a computer to read the fault code and see which circuit is reporting a fault.

Where are you based?

[Auto Addict]

What model?

And as said, what part of the country are you in?

[Tafty]

It could be something really simple as the plug and socket underneath the front seats which has worked loose or has loose connections, quite a common problem and very easy fix - either disconnect and reconnect the switch(es) or as has happened to me a few times over the years, a quick move backwards and forwards of the seat did the trick with mine. HTH

remember trial and error is useless.

The light wont go out, unless turned out using a computer.

So until you know what to look for, I wouldnt bother.

You may find having it turned off solves it anyway.

Sorry to hijack, but I did start my own thread on this same subject earlier this morning, but then when I saw yours it seemed daft to have to apparently identical questions running consecutively. I have deleted my own thread and now am posting here.

I hope you don't mind Susan.


Having just managed to fix my driver's door window that stopped working I have reassembled my door card etc.

Now for the 1st time my red air-bag warning light is on all the time. I have checked the fault codes and with the exception of the 0170 and 0173 which I am aware of and relate to fuel trim (Kevin Wood and I are working on those this weekend) I have a new code: 0650.

I have looked 0650 up here...

...and found this, which doesn't give me much to go on really.

P0650 Malfunction Indicator (MI) Control Circuit High Instrument
P0650 Malfunction Indicator (MI) Control Circuit Low Instrument
P0650 Malfunction Indicator (MI) Control Circuit Open Instrument

Is there any way of telling which, of the multitude of air-bags the car has, is causing the problem or can a Tech2 find this sort of detail out?

I know that recent history tells me that it is most likely to be the air-bag in the bottom of the driver's door, but the light wasn't coming on until after the door was reassembled. The warning light never came on until the 2nd time I drove the car after fixing the window so I can't aford to assume it is that one.

Confucious say "assumption = the mother of all f*ck-ups"

I'm also nervous about going anywhere near any air-bag connections in case I set something off.

Any advice appreciated.

[Jimbob]

Right.

A cheapo tech2 will tell you which CIRCUIT is at fault, which helps
a real tech2 also obviously does this, but by using live data you can view the resistance of each component, which pinpoints it exactly!

Which is how I know when my light comes on, I drop the drivers seat back, wiggle the side airbag connector, use the cheapo tech2, and fixed again for a couple of months.

Hi,

..heh..I live in Finland, Espoo...

How to deactivate airbags?

Disconnecting battery?

You need to get the fault code read by a TechII, to see what made it come on.

The only way to reset the airbag light is with a TechII, or a cheapo TechII from e-bay.

You will need to get it hooked up to a decent code reader that can read the airbag ECU to locate the fault I'm afraid.

The cheapo tech2 may help isolate the fault.
