No. 1 Cooling Fan Relay

INSPECTION
1. INSPECT NO. 1 COOLING FAN RELAY





a Remove the No. 1 cooling fan relay (Marking: FAN NO. 1).





b Inspect the No. 1 cooling fan relay continuity.
1 Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
2 Check that there is no continuity between terminals 3 and 5.
If there is continuity, replace the relay.





c Inspect the No. 1 cooling fan relay operation.
1 Apply battery positive voltage across terminals 1 and 2.
2 Using an ohmmeter, check that there is continuity between terminals 3 and
If there is no continuity, replace the relay.
d Reinstall the No. 1 cooling fan relay.
2. INSPECT NO. 2 COOLING FAN RELAY





a Remove the No. 2 cooling fan relay (Marking: FAN NO. 2).





b Inspect the No. 2 cooling fan relay continuity.
1 Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
2 Check that there is continuity between terminals 3 and 4.
If there is no continuity, replace the relay.
3 Check that there is no continuity between terminals 3 and 5.
If there is continuity, replace the relay.





c Inspect the No. 2 cooling fan relay operation.
1 Apply battery positive voltage across terminals 1 and 2.
2 Using an ohmmeter, check that there is no continuity between terminals 3 and 4.
If there is continuity, replace the relay.
3 Check that there is continuity between terminals 3 and 5.
If there is no continuity, replace the relay.
d Reinstall the No. 2 cooling fan relay.
3. INSPECT NO. 3 COOLING FAN RELAY





a Remove the No. 3 cooling fan relay (Marking: FAN NO. 3).





b Inspect the No. 3 cooling fan relay continuity.
1 Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
2 Check that there is no continuity between terminals 3 and 5.
If there is continuity, replace the relay.





c Inspect the No. 3 cooling fan relay operation.
1 Apply battery positive voltage across terminals 1 and 2.
2 Using an ohmmeter, check that there is continuity between terminals 3 and 5.
If there is no continuity, replace the relay.
d Reinstall the No. 3 cooling fan relay.
