ET035LOW SPEED ENGINE FAN
RECOMMEND AT IONS No failure on the water temperature sensor circuit must be present in
order to perform this diagnostic.
Check:
- engine fan condition
- engine fan resistance condition
- condition f the engine fan mass connection
-l ow speed engine fan supply
-s upply line between engine fan and engine fan relay
M end if necessary.
C heck the connection and condition of the connector of the low speed engine fan relay
Re place the connector if necessary.
Rem ove the rela y of the low spe ed engine fan
C heck, with the contact set on, the supply presence +12 volts at pole 1 of the rela y.
M end if necessary.
Measure the relay coil resistance.
Re place the rela y of the low spe ed engine fan, if necessary.
Connect the 90 ways terminal box instead of the computer and check the in su la t i on, continuity and
absence of the parasite resistance on the connection between: Pin 8 injection computer > Relay of the low speed engine fan

M end if necessary.
Idling regime
< minimal limit RECOMMENDAT IONS The idling RPM is too low
- Check the enriching adjustment operation.
- Clean the air supply circuit (valve body, idling regulator), which may be clogged.
- Check the engine oil level ( too high ? bubbling).
- Check the engine compressions.
- Check the valves clearances and the distribution setting.
- Check the ignition.
- Check the injectors.
If all checked eleme nts are correct, replace the idling regula tor
Idling regime
> maximal limit RECOMMEND AT IONS The idling RPM is too high
- Check the oil level
- Check the good operations of the atmospheric pressure sensor.
- Check possible leaks at piping connected to the inlet manifold.
- Check the electric valve s with pneumatic control.
- Check the manifold gaskets.
- Check the gaskets of the valve body.
- Check tightening at servo-brake.
- Check the presence of nozzles in the connection hose s of the oil vapors re-aspiration circuit.
- Check the valves clearance and the distribution setting.
If all checked eleme nts are correct, replace the idling regula tor AFTER Restart the conformity checking from the beginning.

PR030 ENRICHING ADAPTATION IN OPERATION
PR031 ENRICHING ADAPTATION AT IDLING
RECOMMEND AT IONS No failure must be present or memorized.
Perform the steps for memorizing the adaptation values by the injection
computer.
Erase the computer memory. A t warm, when idling adjustment, observe the se paramete rs :
- If one of t hese parameters is moving towards the minimal limit, there is not sufficient petrol or there
is t oo much air.
- If one of the se paramete rs is moving towards the minimal limit, there is too much petrol or there is
not sufficient air.
(See chapter “ Enriching adaptive correction) for the exact limit values)
Ensure the cleaning condition and the good operation of :
- fuel filter
- fuel pump
- fuel circuit
- fuel tank
- air supply piping
- air filter
- spark plugs
C heck :
- Engine compressions
- Valves cle arance
