LIGHTING (INT) LIGHTING SYSTEM(except NR Series Engine) Interior Light Auto Cut Circuit

DESCRIPTION

The main body ECU (multiplex network body ECU) controls operation of the DOME CUT relay in order to supply power to the interior lights. When the battery saving function operates while the interior lights are on, the main body ECU (multiplex network body ECU) opens the DOME CUT relay to turn off the lights.
