B103F62 — Steering column lock authentication failure
Quick answer
B103F62 means the electronic steering column lock did not authenticate with the vehicle. This is an immobiliser-related fault: the column lock may not release, and the car may refuse to start.
What to check first
- Check the 12 V battery state of charge and terminals; a weak 12 V supply causes many electronic faults.
- Check whether other modules on the same network also report communication faults; one module offline can set codes in several others.
- Read all stored fault codes with a scan tool and deal with related codes first.
Can I still drive?
Do not drive. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
