Radiator Cooling Fan Motor Relay: Testing and Inspection
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 3 and 5.
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 cooling fan relay operation.
1. Apply battery voltage across terminals 3 and 5.
2. Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
d. Install 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)
