1999 NISSAN PRIMERA servo

OVERALL FUNCTION CHECK
Use this procedure to check the overall function of the cooling
fan. During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Seri-
ous burns could be caused by high pressure fluid escaping
from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap
by turning it a quarter turn to allow built-up pressure to
escape. Then turn the cap all the way off.
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is
below the proper range, skip the following steps and go to
ªDIAGNOSTIC PROCEDUREº, EC-CD-90.
2) Confirm whether customer filled the coolant or not. If cus-
tomer filled the coolant, skip the following steps and go to
ªDIAGNOSTIC PROCEDUREº, EC-CD-90.
3) Turn ignition switch to ªONº position.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode
with CONSULT-II (LOW speed and HI speed).

3) Start engine.
Be careful not to overheat engine.
4) Set temperature control switch to full cold position.
5) Push Air Conditioner switch to ªONº position.
6) Turn blower fan switch to ªONº position.
7) Run engine at idle for a few minutes with Air Con-
ditioner operating.
Be careful not to overheat engine.
8) Make sure that both cooling fans operate at low
speed.
9) Turn ignition switch to ªLOCKº position.
10) Push Air Conditioner switch and blower fan switch
to ªOFFº position.
11) Disconnect engine coolant temperature sensor
harness connector.
12) Connect 150Wresistor to engine coolant tempera-
ture sensor harness connector.
13) Restart engine and make sure that both cooling
fans operate at higher speed than low speed.
Be careful not to overheat engine.
