Isn't any call from The MRS. considered a drop everything emergency?... LMFAO. Yeah checked Mitchel and All data are as useless as tits on a Boar for giving airbag system codes. Code might be an internal module fault. Did you try to clear the codes or disconnect the battery for awhile  and then maybe remove and reseat the MRS module connector a few times and recheck.  It might have just been a Bogus code set from a low battery being jump started or something simple being made into a big deal from a Turd vehicle to be over analyzed and customer have their  wallet  worked over for nothing at The Stealership.
