The problem was likely related to the long term storage of the bike at my warehouse, inactive for about two years. Luckily, manipulation of the brake levers and vacuum bleeding the system restored function.
Bleeding the brakes by activating the ABS pump and energizing the solenoids is nothing new to me as an auto technician, and I have diagnostic platforms and software to perform the power bleed on modern car and truck ABS systems. Unfortunately, it's not as easy on most motorcycles as there really isn't a widespread standardized communication protocol and the data connectors and cables are proprietary.
My Triumph Bonneville T120 is an exception. It has a multi pin DLC which I can plug an OBD2 Bluetooth adapter into and pair it with my android phone running a TuneEcu app. This allows me to retrieve and clear fault codes, reset the maintenance indicator "wrench" symbol on the clocks, synchronize the throttle bodies, and perform a power bleed of the ABS system.
I wish this was available for my CB1100. Purchasing the factory service tools, software and diagnostic platform is cost prohibitive to say the least.
