A/C Signal: Description and Operation

A/C Cut-Off Control 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:

^ For 2 seconds just after engine start.
^ For 16 seconds at full throttle acceleration.
