B2013 ID DISCORD, IMMU-STRG

Description

INFOID:0000000003375632

BCM performs the ID verification with the steering lock unit and releases the steering lock if both BCM and
steering lock unit ID are same. BCM starts the communication with the steering lock unit when Intelligent Key
is carried into the passenger compartment and the push-button ignition switch is pressed.
