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 the main fuse box located on the left side of the engine compartment.
