Scoupe L4-1468cc 1.5L SOHC (8 VALVE) (1991)
Air Conditioner Control System
To test the Air Conditioning Signal to the ECU, locate pin #6 of connector C30-1 on the ECU, and test for the presence of power with the A/C switch in
the "on" position. Battery voltage should be available with the switch in the "on" position and 0 volts should be present in the "off" position.
NOTE: To test pins do not remove the connector from the ECU, instead insert a straight pin or needle from the back side of the connector to access the
pin.
