YES

>> GO TO 2.

NO

>> Perform trouble diagnosis for power supply circuit.

2.

CHECK COOLING FAN MOTOR CIRCUIT-1

Check the voltage between cooling fan relays-2, -3 harness connectors and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 4.

3.

CHECK COOLING FAN RELAY OUTPUT SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect IPDM E/R harness connectors.

3. Check the continuity between cooling fan relay-2, -3 harness connectors and IPDM E/R harness connec-

tor.
