Title: Firmware Release Notes, MBB V42 and V43
Post by: karlh on November 13, 2025, 08:00:51 PM

MBB firmware V43 was recently released, but the Zero website only has release notes through V41.  After an Email and phone call to Zero, I received the following:

MBB V42
•   Enhanced key switch fault detection and handling.
•   Improved vehicle behavior when key switch input is lost during operation.
•   Added safety interlocks for OTA updates.
•   Maintained lighting and MBB operation during key switch faults.

MBB V43, BMU V18
•   Fix:  Resolved behavior that would cause a false Isolation fault during charging.
•   Fix: Resolved behavior that would block the ability to commission the motor with DIAG4Zero after replacing the motor controller.
