Engine Cooling System: 1F-9
NOTE
• When making this test, it is not necessary
to remove the cooling fan.
• The voltmeter is for making sure that the
battery applies 12 V to the motor. With the
fan motor with electric motor fan running
at full speed, the ammeter should be
indicating not more than 5 A.
4) Connect the cooling fan motor coupler.
5) Reinstall the removed parts.
Cooling Fan Relay Inspection
B944H11606010
Refer to “Electrical Components Location in Section 0A
(Page 0A-7)”.
Inspect the fan relay in the following procedures:
1) Remove the right rear frame cover. Refer to “Exterior
Parts Removal and Installation in Section 9D
(Page 9D-4)”.
2) Disconnect the cooling fan relay coupler and remove
the cooling fan relay (1).
3) First check the insulation between “A” and “B”
terminals with tester. Then apply 12 V volts to “C”
and “D” terminals, (+) to “C” and (–) to “D”, and
check the continuity between “A” and “B”.
If there is no continuity, replace it with a new one.
