A/C Cut-Out System
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Mazda Tribute, 2002 Mazda Protege5, 2002 Mazda Protege, 2002 Mazda Millenia, and 2002 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
During acceleration (60 percent throttle or more with transmission in gear and clutch pedal released) and about 2-5 seconds after starting the engine and during heavy acceleration, the PCM opens the A/C relay, cutting off power to the A/C compressor clutch. This improves idle after start-up and performance during heavy acceleration.
