COOLING ENGINE FAN NOT WORKING
(for vehicles without air conditioning)
Replace
fuse
F01
.
Check fuse F01 from engine
compartment. Is it good?
Replace water temperature sensor.
Replace the control relay of the
cooling engine fan.
Replace the cooling engine
fan assembly.
Start the vehicle’s engine.
Disconnect the water
temperature sensor. Is the
cooling engine fan working?
Check the control relay of the
cooling engine fan Is it good?
Is any voltage between pins 1
and 2 of the cooling engine fan
connector?
The wiring
is
damaged.
Fix it.
Stop the vehicle engine.
Check the continuity and resistance against vehicle mass between:
- pin B2 connector of water temperature sensor pin 13 UCE injection;
- pin B1 connector of water temperature sensor pin 73 UCE injection;
- pin 3 connector of cooling engine fan control relay exit fuse F01;
- pin 5 connector of cooling engine fan control relay pin 2 connector of
cooling engine fan
- pin 1 connector of cooling engine fan vehicle mass;
- pin 1 connector of cooling engine fan control relay pin D 5 connector
of actuators relay;
- pin 2 connector of cooling engine fan control relay pin 8 UCE injection.
Are they good?
Replace UCE injection.
ATTENTION!
The injection computer damaging is probably due to an electric
shock. Before mounting a new injection computer, the cause of its
damaging must be found.
