Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
The CCM can cause data communication faults in allot of cases and cause the no start that you see here.It may be that it failed completely when a voltage surge occurred from disconnecting and reconnecting the battery.
If you havent yet try locking and unlocking the doors with the remote or power door lock button in the vehicle and see if this allows starting of the vehicle then.If this does not work at all then you will have to have the fault codes checked/read out with a compatible scan tool to see what codes are set in all computers in your model then from there those codes diagnosed and repaired to correct this issue here.If locking and unlocking does not work I suspect the CCM data signals is the cause here and the CCM needs replaced most likely.
