Fault finding – Interpretation of statuses13B
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.

Command RZ034 reinitialises the computer memory.
With the ignition on:
– Use command RZ034.
– Switch off the ignition and wait for the message Communication lost with computer.
– Switch on the ignition again.
– Configure the injector codes using command SC002 Enter injector codes
– Run the programming commands (see configuration and programming).
– Switch off the ignition and wait for the message Communication lost with computer.
Perform a road test to reinitialise the vehicle parameters.

ALP2 Starting difficult (or impossible)
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not eliminated, perform the following checks.
Is it difficult or impossible to start the engine?
PART A:
Check the engine earths.
If the engine speed is less than 200 rpm, refer to Technical Note 6014A, Checking the charging circuit, Starter
fault finding, Starter.
If an engine speed of 200 rpm is achieved with starter motor in operation, PR055 Engine speed.
If the engine speed shown on CLIP is zero and the engine is running, check the resistance of the engine speed
sensor between the following connections:
– Connection code 3BG,
– Connection code 3BL,
of component 149.
Replace the sensor if the resistance is not between 200 Ω and 270 Ω at 20°C.
Check the continuity and insulation of the following connections:
– Connection code 3BG,
– Connection code 3BL,
between components 120 and 149.
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.
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting and condition (overheating) of the sensor.
Replace if necessary.
Check the synchronisation of the camshaft sensors and the engine speed sensors with the display of ET238
Synchronisation. If synchronisation is not active, refer to the checks described in DF195 Camshaft/engine
speed consistency.
Check the fuel circuit for leaks using test 3 Low pressure circuit check.
If test 3: Low pressure circuit check is correct.

is the engine running on all cylinders?
Check the operation of the injectors, run test 10 Poor injector operation.
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve, and the damper valve (see Interpretation of statuses and
Interpretation of parameters).
Check the consistency of the signal for the air flowmeter, the engine coolant temperature sensor, the fuel
temperature sensor and the engine speed.
Check the connectors, the continuity, and the absence of interference resistance of the air flowmeter (apply DF056
Air flow sensor circuit), the engine coolant temperature sensor (apply DF001 Coolant temperature circuit), the
fuel temperature sensor (apply DF098 Fuel temperature sensor circuit), and the engine speed (apply DF195
Camshaft sensor - engine speed consistency).
Check:
– That the diesel filter is not clogged.
– That there are no leaks on the high and low pressure diesel circuits: run test 3 Low pressure circuit check.
– The connection of the oil vapour rebreathing circuit.
– The rail pressure regulator (MPROP) (jammed - stuck), apply the interpretation of command AC011 Rail
pressure regulator.
Check the engine timing (and the position of the high pressure pump sprocket). See the procedure in the
Workshop Repair Manual if necessary.
Test the high pressure fuel circuit:
Run the scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
If the fault is still present, contact the techline.
