A/C-Cut Control System

Engine Control Module (ECM) uses various input signals for controlling A/C-cut control system. A/C-cut control system interrupts A/C compressor operation for a fixed period of time when vehicle accelerates from low engine speed. Also, when turning the air conditioning compressor ON or OFF in accordance with the engine condition, driveability is maintained.
