3. Acceleration Cut System





3. ACCELERATION CUT SYSTEM
The A/C relay turns the A/C system on or off. The on-off operation of the switch is transmitted to the ECM.
The A/C relay breaks the current flow to the compressor, through the use of an output signal from the ECM, for a certain period of time when a "full-throttle" signal (emitted from the throttle sensor) enters the ECM while the compressor is operating. This prevents the degradation of acceleration performance and stabilizes. A/C relay located in the main fuse box.
