Dimmable Backlighting

When the parking lamps are on, the smart junction box (SJB) monitors the input from the instrument panel dimmer switch. The SJB sends a pulse-width modulated (PWM) voltage to the dimmable components and switches based on input received from the instrument panel dimmer switch.

The SJB also sends a message over the network to the audio unit, the DVD player, the climate control assembly, and the instrument cluster to indicate the backlighting intensity level.
