AS6 and AS6B2 Product Advisory

This applies to Autoswitch Model AS6 and AS6B2 installed on BMW CAN-BUS Motorcycles 1200 series year 2007 and up only. No AS5 series are affected.

There are a number of these bikes (USA models 20% estimated) which emit some sort of EMP (ElectroMagnetic Pulse) from their electrical system. BMW has recently released a technical bulletin related to "spurious signals" from the bike. The EMP causes the Autoswitch AS-6B and AS6B2 to reset itself. The reset causes the Autoswitch circuit or microchip to perform a power-on sequence. The Autoswitch always powers up in the OFF state thus the reset leaves the driving lights OFF until rider performs a new ON sequence.  In simpler terms, the lights will turn OFF and must be turned ON again. The EMP happens at unpredictable times, depending on engine RPM and time in use.

Because we have been unable to duplicate the problem on test bikes we are unable to offer a solution or repair at this time. Unable to make a major R&D investment and keep price levels where buyers prefer, the AS6 and 6B2 will be phased out end of 2009. The AS5 series will continue through 2010.
