Unfortunately, neither can be bypassed. A good auto electric shop can usually test/diagnose those 2 units. Shop labor is usually $100.00 an hour and will waive that fee if you have them do the repair. I've looked online and noticed that the BCM is roughly $60.00 to $100.00 on like eBay and such. Hope this helps and thanks again for using 2CarPros.
