In some cases when testing BSS protocols, after the VC-11R identifies the protocol it starts to „lose” the
identification and tries to identify it again and again. When this happens, you have to press 13,5 and 15,5
buttons simultaneously, what puts the tester into manual mode, allowing you to continue the test.
It happens because the signal contains not only data for alternators, but also some „useless” information
that can interfere with the tester.
