Delphi Corp.'s living environment control module (LECM) is a new feature on Volvo Trucks North America Inc.'s redesigned VN Series of Class 8 commercial vehicles.

LECM is an integrated control module for the sleeper area of heavy-duty trucks. It is a mechatronic product; meaning electrical and mechanical components are integrated into a single system. It centralizes most of the sleeper cab's fuses for lights and outlets, and controls all plug-in accessory power feeds.

LECM also houses functions such as the interior light buttons, auxiliary controls for HVAC, and the clock/alarm/park heater timer from a single module.
