Description And Operation: Description
Vehicles manufactured for Europe-Middle East-Africa (EMEA) markets only have an electromechanical device called an Electric Steering Lock (ESL) that locks (key OFF) and unlocks (key ON) the steering upon request by the Body Control Module (BCM). The steering lock module is located on the steering column in the same position where the ignition switch would be found. The electric steering lock is only present on cars with FOBIK-type key and the Keyless Ignition Node (KIN) module (Start/Stop button). Cars with a key with groove have the classic mechanical steering lock.
The ESL module transmits data and communicates with the other modules involved in the immobilizer system via CAN-C2.
In normal operating conditions the ESL module unlocks the steering column if, and only if, the key in the vehicle is identified by the immobilizer system as a "valid key".
