It may be the same problem I had with my 2003 rubbish merc, mot fail airbag light on.
The airbag connectors are great quality gold plated, the car connector was rubbish tin strip so a little galvanic corrosion and you have a high resistance connection wheen the ecu looks/checks the system and throws up an error.
You need to analyse the system to find which one is throwing up the error, then fix it by cutting out the bad ones ,I just did all of them on the merc.
Then I had to have the dealer reset it has it was a "safety system" £125 for 5 mins work , chrysler /merc cr@p.
Don't work on airbag systems if your not confident or competent!
Hope that helps
