Normal Operation
The lighting control module supplies a variable pulse width modulated (PWM) voltage to the dimmable switches and components through circuit 484 (OG/BK). The non-dimmable switches and components receive voltage through circuit 964 (DB/LG) from the central junction box (CJB) when the ignition switch is in the ACC or RUN positions. The switches and components are grounded through circuit 57 (BK).
