COOLING SYSTEM – Electric Cooling Fans
5. INSPECT NO.2 COOLING FAN RELAY
("A.C FAN NO.2")
A. Inspect relay continuity
(a) Using an ohmmeter, check that there is continuity
between terminals 2 and 6.
(b) Check that there is continuity between terminals 1 and
3.
(c) Check that there is no continuity between terminals 1
and 4.
If continuity is not as specified, replace the relay.
B. Inspect relay operation
(a) Apply battery voltage across terminal 2 and 6.
(b) Using an ohmmeter, check that there is no continuity
between terminals 1 and 3.
(b) Check that there is continuity between terminals 1 and
4.
If operation is not as specified, replace the relay.
6. INSPECT NO.3 COOLING FAN RELAY
("A.C FAN NO.3")
(See procedure EFI Main Relay on page FI–47)
7. INSPECT COOLING FANS
(a) Connect battery and ammeter to the cooling fan
connector.
(b) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
