Nissan Juke Service and Repair Manual : Cooling fan
Component Function Check
1.CHECK COOLING FAN FUNCTION
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “FAN DUTY CONTROL” in “ACTIVE TEST” mode of “ENGINE” using CONSULT-III.
3. Check that cooling fan speed varies according to the percentage.
Without CONSULT-III

NO >> Repair or replace error-detected parts.
6.CHECK COOLING FAN CONTROL SIGNAL CIRCUIT
1. Disconnect IPDM E/R harness connector.
2. Check the continuity between cooling fan control nodule harness connector and IPDM E/R harness connector.
3. Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 7.
NO >> Repair or replace error-detected parts.
7.CHECK COOLING FAN CONTROL MODULE OUTPUT SIGNAL CIRCUIT
1. Reconnect all harness connectors disconnected.
2. Disconnect cooling fan control module harness connector.
3. Turn ignition switch ON.
4. Check the voltage between cooling fan control module terminals and ground.
Is the inspection result normal? YES >> GO TO 8.
NO >> Repair or replace error-detected parts.
8.CHECK COOLING FAN MOTORS -1 AND -2
