Airbag light flashing, pre-tensioner??

[vexorg]

I had the airbag light flashing yesterday.
Got home to read the codes from the ABS module and it says "RH pre-tentioner"
I presume this is at the seatbelt buckle, they dont liike like they have pre-tensioners, more like a solid metal bar holding the catch.

Do they K12s have pre-tensioners? if so where are they?

No one come across pre-tensioner issues on the micra?

Looks to have been a bad connection on the pre-tensioner. It's located at the bottom of the seatbelt.

Pulling the seatbelt or hitting the cover would make the light come on after clearing the fault.
Pressed the connector and wires in togther and doesn't happen now.

Pre-tensioners sometime fire they are a one use item. the wires sometimes have issues as you have found also.
I have not noticed this with micra before but am currently in the process of doing corsa ones because it disables the airbag apparently.
do you also have some sort of buckle at the pillar side next to door that's what the corsa ones are like.

Its usually an issue with the wires and when the resistance of that wire is not correct so would read lower.
this is what I found so far hope this helps.

The pretensioner is completely integrated into the reel part at the bottom of the door pillar.

If it comess back then I'll probably replace the pre-tensioner

Do you think that when this problem shows up that it can throw codes for abs system because they are linked.
I'm getting both that and an af-13 code that's pointing to the auto box.
I'm sure the ABS is linked and it wants bleeding, the rear brakes probably but the dealership did not find anything on last mot.
Btw good luck with the pre tensioner

Not sure on that, mine has only been the airbag light, and the pretensioners are part of that system.
