ELV is a mechanical failure that can occur in the steering column lock. This condition is independent of any other vehicle fault. If the ELV system malfunctions, the vehicle will not start even with a working key, as the steering column lock will not activate. In such cases, a replacement ELV steering column lock must be installed and programmed to the vehicle.
