About B1007

B1007 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.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1007 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.

Code Information

The Body Control Module (BCM) in Holden vehicles uses Electrically Erasable Programmable Read-Only Memory (EEPROM) to store critical non-volatile data including vehicle configuration settings, learned adaptive values, security codes, and calibration parameters. DTC B1007 is set when the BCM's microprocessor detects a failure during an EEPROM write operation — specifically, if the data does not match after three consecutive write attempts, the module flags this code and redirects future writes to an alternative memory area as a fallback. This fault is commonly associated with unstable supply ...
