# Service bulletin TSB 25\-05

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's 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.
