Hi,

I'm a newbie in the world of all of this kind of stuff with my Corsa being my first car. It was great for a year before I had to bump start it (battery was flat) but this caused the timing belt to go out of whack. A mechanic fixed this for us. I also replaced the battery as it needed to be replaced due to the old battery not holding a charge for no more than like a week.

After replacing the battery the passenger's airbag light just keeps flashing whenever the ignition is turned on as well as the airbag light on the dash. I've bought an OP COM to try and diagnose the issue and from what I've seen it simply cannot communicate with the IPC or SDM (it says 'No communication'). I saw another thread with a similar issue (except my car still starts) and it seems like that it could be an issue with the connector of them.

As I'm a complete newbie I have no real idea how to check the connectors. All I know is it is somewhere underneath the gearstick but I'd not have a single clue on how I'm supposed to access it.

Any advice is useful,
Thanks!

Hmmmm this mlcould be a tricky one, because corsa Ds can throw up issues if the battery dies, but it also could be innocent. What I would do is see if you can find another garage to try scan the vehicle, if you ask them could the scan you vehicle to get the trouble code if you throw them £10. This way if there system connects you know it's just something with your opcom. ( @Koicarpkeeper is the man for vauxhall scan software. ) If they cannot read the car it could be a deeper issue, with r you could take it straight to a vauxhall specialist or dealer and see if they can scan it and see if they have same issue

IPC = Instrument Panel Cluster.

If there is no communication with that, no instruments would work, no speedo, no rev counter and so on.

I have seen these "No communication" which were just "historic"

What you want to do is to see if Opcom says they are "Present" if not, try to erase them and see if they return. (What i mean is, if the IPC and/or SDM does not talk to the BCM, then the BCM will also have codes about this, stored.)

There has been problems where a jumpstart has "fried" the BCM, but from memory, that has lead to no-crank, No-start so probably not that.

Again...From memory the SDM is on high-speed CAN, and the IPC is probably on mid or single wire CAN, so probably not the usual "Opcom, has bad solderings on a relay, making it unable to connect to one of the CAN's "

A quick test of the Opcom is if you know someone else, that has an Vauxhall, plug Opcom into theirs and try to connect to SDM/IPC. This will rule out Opcom being bad.

I know this last advice is probably silly....On my car, if the passenger airbag is turned off, when i do ignition on, there is a symbol with "Airbag 2" flashing in the display in the middle. I Know not all Corsa's has this, some only have a smaller one.

Is it possible that for cars without the "trip computer" display, the airbag lamp flashes if the airbag is turned off ?

To enable or disable the passenger airbag do this.

1. Turn ignition to on, but not crank
2. Within a second of 2, press and hold the passenger airbag button on the centre console for several seconds until you hear a beep.

This will turn the passenger airbag on or off, depending on whether it was on or off before

Maybe it's just turned off, and warning you about that. ?
