Adaptive Idling Control System (LH 2.4)

Adaptive idling control system (LH 2.4)

The adaptive (intelligent) idling control system varies the idling speed and IAC setting continuously and automatically compensates for all normal variations.

The microprocessor "remembers" the opening the IAC valve had the last time the engine was run at idling speed. This system reduces the need for service and the setting is constantly maintained at a high level.
