Left Steering Wheel SWITCHPACK
The left steering wheel switchpack has a Local Interconnect Network (LIN) bus connection to the Instrument Cluster (IC).
Thw switch assembly contains a control module. The steering wheel switchpack microcontroller reads the capacitive sensor of the switchpack to detect the selected switch function. The function confirmation is via a central microswitch.
The control module converts this information into LIN bus message which is passed via the Clockspring (CLKSPG) to the IC.
