Compressor Clutch Relay: Description and Operation
Used by fuel injection ECU.
The A/C cut-off relay (located in front of the driver side strut tower) receives a signal from the throttle position sensor, when the throttle valve is in the
full load position. The relay will then open and interrupt the A/C compressor operation. The A/C compressor will resume operation as soon as the
throttle position sensor is no longer in the full load position.
The fuel injection ECU monitors the A/C system via a connection to the A/C cut-off relay.
