4 DETECT MALFUNCTIONING PART
Check the following.
IHarness connectors M70, E125
I10A fuse
I40A fusible link
IHarness for open or short between cooling fan relay and fuse
©Repair open circuit or short to ground or short to power in harness or connectors.
5 CHECK GROUND CIRCUIT
1. Turn ignition switch ªOFFº.
2. Disconnect cooling fan motor-1 harness connector and cooling fan motor-2 harness connector.
