Hi, sorry for yet another airbag post but couldn't find any info hidden in the forum. The airbag and flashing button has appeared on my daughters Corsa D 2012. The local garage ( specialist tuners not a cowboy outfit) has stated their equipment cannot get comms with the airbag and would need to be investigated. I have checked connectors under seats and inside seat wiring and all looks ok and the only thing of note is that the battery was disconnected for a short time.

Where do I start with this or can the dealer get around this ?. Nothing was moved and it just came on. The fuse is ok so is the problem in the wiring from the ecu to the airbag ecu or from their the airbags ? I just want to check wiring and not put voltage in their for obvious reasons. Thanks.
