About B101E

B101E 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.

B101E 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) or related Electronic Control Unit sets DTC B101E when, upon ignition ON with battery voltage between 9V and 16V and normal data bus communications, it fails to detect a valid software calibration or security code in its internal memory. This indicates the control module software was not programmed, has been corrupted, or the VIN and security configuration is missing. The BCM stores calibration identifiers, key codes, immobiliser data, and vehicle build options (market, transmission type, optional equipment) in EEPROM, and validates this data on every wake up.
