MX-5 Miata L4-1597cc 1.6L DOHC (1992)
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.
