Seat Heating
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
Seat heating selections on the TSD are transmitted on the MOST (media orientated system transport) ring to the information and entertainment module, which relays the selections to the ATC module on the medium speed CAN bus. The ATC module then sends a message, on the medium speed CAN bus, to the CJB (central junction box), which provides a feed to the seat heater elements.
