Compressor Clutch Relay: Description and Operation

A/C Cut-Off System

In order to maintain good driveability with the air conditioning system in operation, the ECU will initiate A/C cut-off under certain driving conditions by
de-energizing the A/C clutch relay.  The system acts to improve idle smoothness just after starting and to maintain acceleration performance.

A/C cut-off operates under these conditions:

1.

For approximately 2 seconds after engine start.

2.

For approximately 5 seconds at full throttle.

3.

For approximately 3 seconds when accelerating from a stop.
