STARTING
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
AUTHORISED
PROHIBITED
Starting the vehicle is authorised when the UCH authorises starting.
Status ET076 changes to AUTHORISED if the vehicle cards are recognised and the
engine immobiliser is inactive.
If the card is not recognised by the UCH, starting the vehicle is prohibited.
Status ET076 is PROHIBITED and the vehicle cannot be started.
Run fault finding on the UCH (see 87B, UCH).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

IMPACT DETECTED
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
If the vehicle has been involved in an accident, the injection computer receives the
impact signal via the multiplex network and may switch off the ignition. Status ET077 is
at YES.
Switch off the ignition for ten seconds, then switch it back on to enable the engine to start.
Carry out a multiplex network test and deal with any faults.
Clear the injection computer faults, even if no fault is present.
In normal operating conditions, status ET077 is NO when the computer has received no
impact signal.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

ET088
REQUEST TO START COMPRESSOR
ACTIVEThe air conditioning request has been made by the driver when pressing one of the air
conditioning controls (Auto, or AC).
Status ET088 becomes ACTIVE and the computer authorises or does not authorise air
conditioning depending on the operating conditions.
If status ET088 does not become ACTIVE after pressing the control button (See 62A, Air
conditioning).
INACTIVE
When the driver deactivates the air conditioning, status ET088 must become INACTIVE.
If this does not happen, (See 62A, Air conditioning).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

ET104
INJECTOR CODE USE
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
Status ET104 is YES if the IMA option (individual injector correction) is activated in
the injection computer.
All the injectors have IMA codes etched on the bakelite body, but not all computers
use them.
In the case of a computer configured with the IMA option, the injector codes must be
entered into the injection computer in the following scenarios:
– when one or more injectors is replaced,
– when the injection computer is replaced,
– when the injection computer is reprogrammed.
If the injector codes are not programmed after these operations, fault DF276
Injector code programming will be present, and the engine will operate in defect
mode.
Run command SC002 Enter injector codes applying the procedure described in
the interpretation of this command.
Status ET104 is NO if the computer is not configured to interpret the IMA codes
(individual injector correction).
WARNING
A computer without the IMA option can be replaced by a computer with this option.
In this scenario status ET104 changes to YES after replacing the computer.
Fault DF276 Injector code programming will be present and the engine will operate
in defect mode.
In this case, run command SC002 Enter injector codes, applying the procedure
described in the interpretation of this command.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

FAULTYStatus ET104 is FAULTY if the computer does not have IMA codes stored.
Fault DF276 Injector code programming is present and the engine operates in defect
mode.
Run command SC002 Enter injector codes applying the procedure described in the
interpretation of this command.
If at the end of the procedure status ET104 remains FAULTY, contact the Techline.

SYNCHRONISATION
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
WARNING
Synchronisation is carried out during the engine starting phase. This is established between the camshaft
position sensor and the TDC sensor.
Once this synchronisation has been carried out, it enables the computer to identify cylinder no.1 and to
ascertain the precise position of the cylinder's top dead centre.
INACTIVE
COMPLETED
When the engine is stopped but the ignition switched on, cylinder no. 1 is no longer
indicated.
Status ET238 is INACTIVE, no synchronisation between the crankshaft and the
camshaft is performed.
Synchronisation is carried out during the engine starting phase.
Cylinder No. 1 is indicated and synchronisation will be performed once the engine is
started.
Status ET238 is "COMPLETED".
If after several attempts to start the engine status ET238 remains INACTIVE, refer to the
interpretation of the following faults:
–DF005 Engine speed sensor circuit
–DF097 Camshaft sensor circuit
If the engine still does not start, (see Customer complaints, ALP2 Starting faults).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

ET341
IMMOBILISER CODE PROGRAMMED
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YESStatus ET341 becomes YES if dialogue is possible between the UCH and the injection
computer and the card code is recognised.
Engine starting authorisation is only given if the code is recognised by the UCH
computer, and status ET003 Engine immobiliser is INACTIVE.
NOThe code remains NO if dialogue between the UCH and the injection computer is not
possible.
Status ET003 Engine immobiliser remains ACTIVE.
The malfunction may result from poor card programming; in this case (see 87B, UCH
and follow the card programming procedure).
If the fault is still present, perform a mutliplex network test, and make sure there is
dialogue between the UCH, UPC and the injection computer.
If dialogue is not established, contact the Techline.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

INACTIVE: This status indicates that the clutch pedal is released.
NOTESSpecial note:
Only perform the 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
ACTIVEClutch pedal depressed.
Non-conformity of the brake signals and or the clutch switch signals can cause the
engine to race during gear changes.
In the event of a fault, check the electrical conformity of the sensor.
INACTIVEClutch pedal released.
Non-conformity of the brake signals and or the clutch switch signals can cause the
engine to race during gear changes.
In the event of a fault, check the electrical conformity of the sensor.
Sensor electrical conformity
ACTIVECheck the condition and fitting of the clutch pedal switch.
Remove the clutch pedal switch then check the insulation between tracks 1 and 2, with
the switch in the rest position.
Repeat this operation with the switch depressed and check the continuity between
tracks 1 and 2.
If these two checks are not in order, replace the switch.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
