A/C Cut Control

A/C CUT CONTROL




- When the ECM receives a "full-open" signal emitted from the throttle position sensor while the air conditioning system is operating, the A/C cut relay turns oft for a certain period of time to stop the compressor This prevents degradation of output during acceleration and stabilizes driveability.
- The A/C cut relay is also turned OFF when the engine coolant temperature is high.
