Hyundai Genesis (DH): AVN System / Steering Wheel Remote Controller (SWRC) Description and Operation
The steering wheel remote controller (SWR) is composed of
four switches and the right top switch is equipped with the Body CAN
communication module.
The left bottom remote controller is either a general type or
a haptic type. The right switch collects signals from the left switch.
These CAN signals are delivered through SRC (clock spring) to BCM via Body CAN.
BCM deliver them via M CAN to the dashboard and AVN system so
that they can be used for the operation of the dashboard and AVN
system.
A Haptic Steering Warning System is to deliver the warning message to the driver with the vibration on the steering wheel.
It is composed of the haptic unit (A) and vibration
generating motor (B) implanted on the steering system as shown in the
following photo.
