About B1000

B1000 is a manufacturer-specific body diagnostic trouble code recorded for Mitsubishi vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

The fault can be triggered by a hard communication loss, intermittent dropouts, or corrupted message frames on the bus. When this code is active the driver may notice that climate or audio b...
