Radiator Cooling Fan Motor Relay: Testing and Inspection

COOLING FAN RELAY INSPECTION
1. INSPECT NO.1 COOLING FAN RELAY




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

Standard:

c. Inspect the resistance.
(1) Using an ohmmeter, measure the resistance between the terminals.
If the resistance is not as specified, replace the relay.

d. Reinstall the No.1 cooling fan relay.
e. Reinstall the relay box cover.

2. INSPECT NO.2 COOLING FAN RELAY




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

Standard:

c. Inspect the resistance.
(1) Using an ohmmeter, measure the resistance between the terminals.
If the resistance is not as specified, replace the relay.

d. Reinstall the No.2 cooling fan relay.
e. Reinstall the relay box cover.

3. INSPECT NO.3 COOLING FAN RELAY




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




c. Inspect the resistance.
(1) Using an ohmmeter, measure the resistance between the terminals.
If the resistance is not as specified, replace the relay.

d. Reinstall the No.3 cooling fan relay.
e. Reinstall the relay box cover.
