ET077IMPACT DETECTED
STATUS DEFINITIONNO: This status indicates that the airbag computer has not detected an impact.
YES: This status indicates that the airbag computer has detected an impact.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
This signal is transmitted by the airbag computer via the multiplex network.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
NOThe status is usually NO as no impact has been detected.
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).
YESIf the vehicle has had an accident, the injection computer receives the impact signal
via the multiplex network and may switch off the ignition. Status ET077 is YES.
Switch off the ignition for 10 seconds, then switch it back on, so the engine can be
restarted.
Clear the faults (even if no fault is present or stored).
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).

STATUS DEFINITIONACTIVE: This status indicates that the thermoplunger is supplied.
INACTIVE: This status indicates that the thermoplunger is not supplied.
NOTESStatus only available on certain Vdiag48 (depending on vehicle equipment).
INACTIVEStatuses ET205, ET206, ET207 are INACTIVE with the ignition on and the engine
stopped, or when the engine is warm.
ACTIVEStatuses ET205, ET206 and ET207 are ACTIVE when the engine is started, the
engine coolant temperature is low (< 15°C) and the air temperature is low (< 5°).
This program allows the engine coolant to be heated to enable the passenger
compartment to be heated.
The thermoplungers also act both to load the engine to improve regeneration of the
particle filter
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:
DF032 Thermoplunger 1 relay control circuit.
DF033 Thermoplunger 2 relay control circuit.
DF034 "Heating element 3 relay control circuit".

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 statuses do not correspond with the system
programming functions.
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
PERFORMEDStatus ET238 is NOT COMPLETED if the engine has been stopped with the + after
ignition 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 statuses do not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
YESStatus ET341 is YES if dialogue is possible between the UCH computer and the
injection computer and if the key code is recognised.
Engine starting authorisation is only given if the code is correctly recognised by the
UCH computer and status ET003: Engine immobiliser is INACTIVE.
In the event of a fault (see 87B, passenger compartment connection unit,
conformity check).
NOStatus ET341 is NO if dialogue is not possible between the UCH computer and the
injection computer (status ET003 Engine immobiliser 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.

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.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Conformity check with engine stopped and ignition on
The rail pressure value is:
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 engine running, engine coolant temperature > 80°C
The rail pressure value is:
At idle speed: PR038 = 270 bar ± 20 bar
Full load: PR038 = 1700 bar ± 20 bar
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.

– connection code 3LP,
– connection code 3LN.
between components 120 and 1071.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
Vehicle with ignition on, and the engine stopped for over 1 minute:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar,
check the value of PR035 "Atmospheric pressure" by comparing it with the reading on a vehicle in the workshop
which is correct.
If the value of PR035 Atmospheric pressure is not correct (difference greater than 0.1 bar between the 2
vehicles), contact the Techline.
Otherwise (when the value PR035 Atmospheric pressure is correct), change the turbocharging pressure sensor.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.2 bar.
Check the air inlet circuit:
The low and high pressure air circuit is sealed and not obstructed: the pipes and mounting clamps are present
and tightened, turbocharging pressure sensor, intercooler, etc. are fitted.
Check that the damper valve is not jammed closed.
Repair if necessary.
