Bulletin Summary
BMPro made an unintentional change to their programming at some point in MY2026 that affects the generator functions while the ignition is on. Currently the AGS and START GENERATOR buttons are grayed out while the ignition is on. The generator can be started with the ignition off and then it will stay running when the ignition is turned on. It just can’t be started with the ignition already on. The AGS automatically disables, if it’s already enabled, when the ignition is turned on as a code requirement. However, with the current programming, it can’t be reenabled once the ignition is on.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
