Junction Box Electronics

The junction box electronics power the low version of the outside mirror heating system.

The signal is pulse width-modulated and has a frequency of 1 Hz.

The junction box electronics also request the status of the electrochromic interior rearview mirror on the LIN-bus. The mirror electronics feed back the current status of the electrochromic interior rear-view mirror. The junction box electronics send the status to the footwell module on the K-CAN2. The footwell module is therefore aware of the status and is able to control the dimming of the outside mirrors accordingly.
