A/C Signal: Description and Operation
A/C Cut-Off System
PURPOSE
To maintain good driveability with the air conditioning system in operation, the PCME will initiate A/C cut-off under certain driving conditions by
de-energizing the A/C clutch relay.
OPERATION
System acts to improve idle smoothness just after starting and to maintain acceleration performance. A/C cut-off operates under these conditions:
^ For approximately 5 seconds just after engine start.
^ For approximately 5 seconds when throttle is fully.
^ For approximately 3 seconds when transmission is shifted from N range to D range.
