A/ C Cut Control Circuit
CIRCUIT DESCRIPTION
This circuit cuts the air conditioning operation during the vehicle acceleration in order to increase an accel-
eration performance. During the acceleration with the vehicle speed of 30 km/h (19 mph) or less and acceler-
ator pedal opening angle of 45˚ or more, the A/C magnetic switch is turned off for several seconds.
The air conditioning is also controlled by the ECU outputting the engine coolant temperature to the A/C am-
plifier.
