Galant L4-2.0L SOHC (1989)
Main Relay (Computer/Fuel System): Testing and Inspection
Ignition Switch-ST and Control Relay
System Schematic
To test the Ignition Signal to the ECU, locate pins 107 and 102. Test for the presence of battery voltage with the ignition key in the "on" position. There
should be battery voltage present. If no voltage is present, then test for battery voltage at the control relay pins 2, 3, 4 and 8. If no voltage is present, test
relay or repair harness.
CONTROL RELAY
Fig. 1 Control Relay
Caution
Use caution when connecting jumper wires to the relay. If they are incorrectly connected the relay will be damaged.
Test control relay by checking continuity between the following terminals of the control relay coil.
TERMINAL # ............................................................................................................................................................................................... CONTINUITY
3 - 5 ...................................................................................................................................................................................... Conductive (Approx 95 Ohms)
2 - 5 ...................................................................................................................................................................................... Conductive (Approx 95 Ohms)
6 - 7 ...................................................................................................................................................................................... Conductive (Approx 35 Ohms)
6 - 8 ................................................................................................................................................................................... Conductive in one direction only
