Left Steering Wheel SWITCHPACK
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The left steering wheel switchpack has Local Interconnect Network (LIN) bus connection to the Instrument Cluster (IC) and to the Infotainment Master Controller (IMC).
The left steering wheel switchpack and the right steering wheel switchpack contains capacitive sensors and microcontrollers.
The switch assembly contains a control module. The steering wheel switchpack microcontroller reads the capacitive sensor to detect the selected switch function. The function confirmation is via a central microswitch.
The control module converts this information into a LIN bus message which is passed via the Steering Wheel Module (SWM) to the IC.
