DTC B100D-96: Column Lock Authorization - Component internal failure: Action

Clear DTC, repeatedly lock and unlock car using the key fob and retest
If fault persists, check that the vehicle battery supply voltage is between 9-16 volts. Rectify as required
Ensure the column lock bolt movement is not obstructed or restricted (the parked position of the road wheels may be exerting a turning force through the steering column, preventing the lock from releasing. The steering wheel may need to be held against the force to allow the column lock to release). Clear DTC, repeatedly lock and unlock car using the key fob and retest
If fault persists, complete a CAN network integrity test using the manufacturers approved diagnostic system. Alternatively, refer to the appropriate electrical circuit wiring diagrams and check CAN circuits between the central junction box, the instrument cluster and the electronic steering column lock. Refer to the appropriate electrical circuit wiring diagrams and check the central junction box, the instrument cluster and the electronic steering column lock power and ground supply circuits for short circuit to ground, short circuit to power, open circuit, high resistance. Repair circuit(s) as required. Clear DTC, perform an on demand self-test and retest
If fault persists, check and install a new electric steering column lock control module as required
