Radiator Cooling Fan Motor Relay: Testing and Inspection

INSPECTION
1. w/ Auto Spoiler: REMOVE LH HEADLIGHT
2. w/o Auto Spoiler: REMOVE ENGINE UNDER COVER
3. INSPECT NO.1 RADIATOR FAN RELAY



a. Remove the No.1 radiator fan relay. (Marking: RADIATOR FAN RELAY)




b. Inspect the No.1 radiator fan relay continuity.
1) Using an ohmmeter, check that there is continuity between terminals 3 and 4.
If there is no continuity, replace the relay.
2) Check that there is no continuity between terminals 1 and 2.
If there is continuity, replace the relay.




c. Inspect the No.1 radiator fan relay operation.
1) Apply battery positive voltage across terminals 3 and 4.
2) Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
d. Reinstall the No.1 radiator fan relay


4. INSPECT NO.2 RADIATOR FAN RELAY



a. Remove the No.2 radiator fan relay. (Marking: A.B.S. (TRAC) RELAY)
b. Inspect the No. 2 radiator fan relay continuity.
1) Using an ohmmeter, check that there is continuity between terminals 1 and 6.
If there is no continuity, replace the relay.
2) Check that there is continuity between terminals 3 and 5.
If there is no continuity, replace the relay.



3) Check that there is no continuity between terminals 2 and 5.
If there is continuity, replace the relay.
