My codes are 1B-00 passenger airbag on/off communication failure and 01-00 airbag module internal failure. One code can cause the other code however after 1.5 days the tech says its narrowed down to the airbag module, a $2900 part. That said, they will install a used part if I can get one. Anyone happen to have a spare kicking around?? Haven't talked to MB yet. Also fix for the cig lighter is a new unit, $280 installed. So far all they have charged me is the $129 Diagnostic fee.
On a side note, Chrysler said there was a 3 year, 60000 km warranty on the module, also covered under extended warranty. I'm SOL on that front. Hope this helps out. I'll try to search the part #.
