COMPONENT PARTS

Steering Lock Unit

Steering lock unit performs steering lock/unlock operation on request from BCM, and power source is supplied from steering lock relay controlled by IPDM E/R.
When push-button ignition switch is pressed while the Intelligent Key is inside the vehicle, BCM performs the
ID verification with steering lock unit. Steering lock unit releases the steering lock based on the result of the ID
verification.
Steering lock unit has 2 switches (steering lock status switch and steering unlock status switch) inside. BCM
judges the steering lock/unlock condition by comparing these switch signals and steering lock unit status signal transmitted from IPDM E/R via CAN communication.
