2006 NISSAN PATROL Engine

DIAGNOSTIC PROCEDURE
INSPECTION START
CHECK OVERALL FUNCTION.
1. Turn ignition switch ``OFF''.
2. Disconnect charge air temperature sen-
sor harness connector.
3. Connect 150Wresistor to charge air
temperature sensor harness connector.
4. Start engine and keep engine speed at
2,000 rpm.
5. Make sure that charge air cooler fan
operates.

cOK
INSPECTION END
CHECK POWER SUPPLY.
1. Stop engine.
2. Disconnect charge air cooler fan relay.
3. Turn ignition switch ``ON''.
4. Check voltage between terminals
V2,
V5and ground with CONSULT or
tester.
Voltage: Battery voltage

cNG
Check the following.
+Harness connectors
M21,E127
+10A fuse
+15A fuse
+Fuse block
M2
+Harness for open or
short between charge air
cooler fan relay and
fuses
If NG, repair harness or
connectors.
CHECK GROUND CIRCUIT.
1. Turn ignition switch ``OFF''.
2. Disconnect charge air cooler fan motor
harness connector.
3. Check harness continuity between relay
terminal
V3and motor terminalV1,
motor terminal
V2and engine ground.
Continuity should exist.
If OK, check harness for short to
ground and short to power.

+Harness connectors
M50,F5
+Harness for open or
short between charge air
cooler fan relay and

Charge Air Cooler Fan Control (Cont'd)
EC-180

Heat Up Switch
The heat up switch is located on the lower side of the instrument
panel. This switch is used to speed up the heater's operation when
the engine is cold.
When the ECM received the heat up switch ``ON'' signal, the ECM
increases the engine idle speed to 1,100 - 1,200 rpm to warm up
engine quickly.
This system works when all conditions listed below are met.
Heat up switch ON
Engine coolant temperature Below 70ÉC (158ÉF)
Shift lever ``P'' or ``N''
Accelerator pedal Fully released
Vehicle speed Below 4 km/h (2 MPH)
CONSULT REFERENCE VALUE IN DATA MONITOR MODE
Remarks: Speci®cation data are reference values.
