A/C Signal: 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:
^ For five seconds after engine start with the A/C switch "ON."
^ For ten seconds when accelerating at more than half throttle, A/C switch "ON," manual transmission in gear and clutch pedal released or automatic transmission selector in any position except "P" or "N."
