A/C cut-off control operation conditions

Operation condition | A/C relay non-energization period | Purpose
--- | --- | ---
At engine start | Approx. 4 s | Improved startability
At drive-away | Approx. 3 s | Improved drive-away performance
During acceleration (throttle valve opening angle 50% or more) | Approx. 5 s | Improved acceleration performance
When the engine coolant temperature is 113 °C {235 °F} | Repeatedly turns on and off every 10 s until the engine coolant temperature is less than approx. 107 °C {225 °F} | Improved engine reliability
When the engine coolant temperature is 118 °C {244 °F} or more | Until the engine coolant temperature decreases to less than approx. 110 °C {230 °F} | Improved engine reliability
At high engine speed (engine speed 6,600 rpm or more) | Approx. 5 s | Improved engine speed stability
