Seat Modules

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 seat modules are equipped only where seat memory is specified. On memory electric seats the seat switchpack is operated on Local Interconnect Network (LIN) bus with the seat modules.

The seat module is located on the underside of the seat cushion frame on both the driver's and passenger's seats. The module is located towards the front of the seat cushion, behind a plastic trim.

The driver and passenger seat modules are connected by hardwired connections to the seat adjustment motors. The seat switchpacks are connected to the seat module with a Local Interconnect Network (LIN) bus. The seat module contains a non-volatile erasable programmable read only memory. The seat module monitors the seat positions and stores information provided by Hall sensors within the seat adjustment motors. All seat memory values and current seat adjustment motor positions are stored in the erasable programmable read only memory.

If power is lost to the seat module, when power is restored the current seat adjustment motor positions are recalled from the erasable programmable read only memory and adopted as the current positions. This allows the relative memory positions to be retained without any need to re-calibrate the seat module.
