BCM self test
Here is a known good capture of BCM self testing the 12 volt ref to the steering wheel audio and cruise control switchs after I unplugged the shorted cruise control switch. Within 1 minute the voltage returned to 12v because I had removed the short. I did not have to clear the code for the BCM to initiate this test. Sorry for the crappy capture but I believe you get the point. diag.net/file/f5164rlyp…
