Legend Sedan V6-3206cc 3.2L SOHC FI (1995)
A/C Signal: Description and Operation
PURPOSE
The air conditioning signal is used to inform the Engine Control Module (ECM) that a request for air conditioning has been made.
OPERATION
When the A/C switch is closed and evaporator temperature is warm enough, the ECM receives a ground signal, informing the ECM that the air
conditioning has been turned on. The ECM then controls the compressor relay and adjusts idle speed to compensate for compressor load.
