Image Processing Control Module (IPCM)
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles with the IPCM have a camera installed in the covers of the rear view mirror support, with the lens directed through the windshield.
The camera is a low resolution image sensor that detects headlamps and tail lamps of the vehicles ahead. The IPCM evaluates the image data, checking for light intensity and location. Depending on the image data, the control module then sends a low or high beam request message to the BCM/GWM assembly via the HS CAN chassis systems bus. The BCM/GWM assembly then controls the shutter in the Xenon projector module accordingly.
