ANSWER:  HI DAN,SENSING DIAGNOSTIC MODULE. DID THE AIR BAGS GO OFF ON THIS CAR ??? IF SO, WHEN EVER  I SEE THIS CODE THE MODULE IS NOT COMMUNICATING WITH THE SCAN TOOL..

QUESTION: Its a 2001 Monte Carlo the ignition locked key would not move so I replaced it with used one also got bcm out of same car  the key turns now but car does not even turn over the radio stopped working when I replaced ignition  I got tech 2 from  work went through seqUence to sdm  in bcm then tech 2 says waiting for data stayed there about 1hour till I shut it off havent checked anytbing else   you turn key and it doesnt start but fan works and lights go from washer fluid low battery and security they just keep repeating over and over

Answer
HI DAN,READ LAST !!!!!!! OK LETS TRY THIS JUST FOR THE HECK OF IT..CHARGE THE BATTERY, TURN THE KEY ON SEE IF THE SECURITY LIGHT STOPS FLASHING AFTER 20 TO 30 MINUTES..IF SO TURN THE KEY OFF AND NOW SEE IF IT WILL START...WHEN YOU TURN THE KEY TO START ,IT WILL CRANK OVER CORRECT ??? JUST WILL NOT START
I HOPE THIS IS THE CASE..THE BCM DOES NOT RECOGNIZE THE NEW LOCK CYLINDER.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
READ THIS FIRST !!!!!!!!!!! IF I READ THIS CORRECT YOU GOT ANOTHER BCM FROM THE SAME KIND OF CAR ??? BUT NOT THIS CAR.. IF THIS IS CORRECT THIS DEFINITELY HAS TO BE FLASHED WITH GM SOFT WARE NO WAY AROUND THAT. IT KNOWS THE VIN# DOES NOT MATCH UP. IT WILL NOT DO ANYTHING IT SHOULD..DO YOU HAVE GM SOFTWARE TO DO THIS..DOWN LOAD IT OF THE GM SITE IF YOU ARE A MEMBER.IF NOT TIME FOR A TRIP TO THE DEALER.... THEN RELEARN THE NEW IGN LOCK CYLINDER TO THE THEFT MOD..LET ME KNOW HOW THIS GOES GOOD LUCK TO YOU,,,TOM...
