LIN Seat Switch
WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
The seat switch communicates all customer requests for seat movement or adjustment via the LIN serial data bus to the seat memory control module. The seat switch may consist of the following controls:
- Seat adjuster switch similar to the typical discrete seat switch
- Massage On/Off switch, if massage is equipped
- 4-way multi-function switch which can be activated Up/Down/Forward/Rearward
- Feature select rotary ring around the outside of the 4-way multi-function Switch
Manipulating the seat cushion and seat back control bar results in the seat memory control module responding in the same way as it would if the resultant requests were made by discrete signals instead of the LIN messaging this switch employs.
