Ignition Switch: Description and Operation

Ignition Switch and Locking Mechanism








The ignition switch assembly also has a locking mechanism which works in conjunction with the immobilization control module and the steering lock control module. The ignition switch mechanism comprises an ignition switch lock solenoid actuator which prevents the ignition switch being rotated unless the key has been recognized by the immobilization control module. A Hall sensor is located in the ignition switch body and senses the rotation of the ignition switch. This signal is transmitted on the K bus and is used by the steering lock control module to confirm the key status with the immobilization control module. Refer to Operation later for the functional description.
