STATUS
DEFINITIONACTIVE: These statuses indicate that the thermoplungers are active.
INACTIVE: These statuses indicate that the thermoplungers are inactive.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
"INACTIVE"Statuses ET024, ET025, and ET026 are INACTIVE when the ignition is switched on
with the engine stopped, or when the engine is warm.
"ACTIVE"Statuses ET024, ET025, and ET026 are ACTIVE when:
– the engine has been started,
– and the engine coolant temperature is low (< 15°C),
– and the air temperature is low (< 5°C).
This strategy allows the engine coolant to be heated and to allow the heating of the
passenger compartment.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Thermoplunger no. 1 relay,
– AC064 Thermoplunger no. 2 relay,
– AC031 Thermoplunger no. 3 relay.
In the event of a fault, refer to the interpretation of faults:

ET238SYNCHRONISATION
STATUS
DEFINITIONSynchronisation is carried out during the engine starting phase. The camshaft position
sensor and the TDC sensor are synchronised. Once this synchronisation has been
carried out, it enables the computer to identify cylinder n°1 and to ascertain the precise
position of the cylinder's top dead centre.
Synchronisation also allows the computer to determine the injection strategy.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
COMPLETEDStatus ET238 is DONE when the engine is started. The computer has identified
cylinder no. 1 and has identified the exact top dead centre position. Injection
phasing and engine management are now possible, and the engine should be
working properly.
NOT
COMPLETEDStatus ET238 is NOT COMPLETED when the engine has been stopped with the
+ after ignition feed on.
If status ET238 remains NOT COMPLETED after an attempted start, consult the
interpretation of fault DF195 Camshaft sensor/engine speed consistency.

STATUS
DEFINITIONYES: This status indicates that the immobiliser code has been programmed.
NO: This status indicates that the immobiliser code has not been programmed.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
"YES"Status ET341 is YES if dialogue is possible between the UCH computer and the
injection computer and the key code is recognised
.
The engine is only authorised to start if the code is correctly recognised by the UCH
computer and statusET003 Engine immobiliser is INACTIVE.
In the event of a fault, (see 87B, Passenger compartment connection unit,
Conformity check).
"NO"Status ET341 is NO if dialogue is not possible between the UCH computer and the
injection computer (status ET003 remains ACTIVE).
This fault may be caused by incorrect key programming or a lack of key programming.
In this case, refer to the UCH fault-finding note (see 87B, Passenger compartment
connection unit) and follow the key programming procedure.
If the key programming is not the cause, run a multiplex network test (see 88B,
Multiplexing) and check that dialogue between the UCH and the injection
computer is possible.
If dialogue is not established, contact Techline.

PR038RAIL PRESSURE
PARAMETER
DEFINITIONThis parameter indicates the rail pressure in bar.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (starting faults, poor performance, stalling etc.),
– after interpretation of command AC225 Rail pressure regulator.
Special notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check: Engine stopped and ignition on
The rail pressure value is between:
0 bar < PR038 < 90 bar if the coolant temperature < 30°C.
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.
Conformity check with the engine running and engine coolant temperature > 80°C
The rail pressure value must be between:
250 bar < PR038 < 290 bar (at idle speed),
1680 bar < PR038 < 1720 bar (full load).
In the event of a fault, refer to the interpretation of fault DF007.

Sensor electrical conformity
Check the continuity and absence of interference resistance of the following connections:
•3LQ between components 120 and 1071,
•3LP between components 120 and 1071,
•3LN between components 120 and 1071.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Vehicle with the ignition on, and the engine stopped for at least 1 minute:
Compare the values of PR041 Turbocharging pressure and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 is greater than 0.1 bar,
check the value of PR035 by comparing it with the reading on a vehicle in the workshop which is correct.
If the value of PR035 is not correct (difference greater than 0.1 bar between the 2 vehicles), contact the Techline.
Otherwise (when the value of PR035 is correct), replace the turbocharger pressure sensor.
If the difference between PR041 and PR035 is less than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035.
If the difference between PR041 and PR035 is greater than 0.2 bar.
Check the air inlet circuit:
Apply Test 4 Turbocharged air inlet circuit check.
Low and high pressure air circuit sealed and not obstructed: ducts, mounting clamps present and tightened,
turbocharging pressure sensor fitted, exchanger, etc.
Check that the damper valve is not jammed closed.
Repair if necessary.
