About B1019

B1019 is a manufacturer-specific body diagnostic trouble code recorded for Holden vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

B1019 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

B1019 sets when the PIM has been programmed with a configuration indicating a manual transmission (M/T) is fitted, yet it is simultaneously receiving valid serial data messages from a Transmission Control Module (TCM), which is only present on automatic transmission (A/T) vehicles. The module interprets this as a vehicle configuration mismatch and stores the fault. In t...
