ET088
REQUEST TO START COMPRESSOR
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
ACTIVE
Status ET088 becomes ACTIVE if there has been a request for air conditioning (press
the AC or AUTO button, with maximum cold) and if status ET004 is YES.
The selection is made on the air conditioning control panel, the request for air
conditioning is transmitted to the UCH which in turn transmits the request to the injection
computer which either authorises or does not authorise the compressor to switch on. If
the injection computer authorises the compressor to switch on, its sends the
compressor on request to the UPC and status ET088 COMPRESSOR ON REQUEST
becomes ACTIVE (Climate control).
If the vehicle is equipped with manual air conditioning, the air conditioning request is
transmitted from the air conditioning control panel to the UCH which then accepts or does
not accept the air conditioning compressor coming on depending on the operating status
of the passenger compartment fan. When the request has been accepted, the request
to switch on the compressor is transmitted to the injection computer which either
authorises or does not authorise the compressor to start.
If the injection computer authorises the compressor to switch on, its sends the
compressor on request to the UPC and status ET088 COMPRESSOR ON REQUEST
becomes ACTIVE.
If there has been no compressor on request and status ET088 remains ACTIVE
(see 62A, Air conditioning).
Note:
Switching on the compressor is only authorised when the engine is running.
Switching on the compressor is ultimately controlled the UPC.
Status ET088 is INACTIVE when there has been no air conditioning request and
when the compressor has not been authorised to come on (ET004 is NO or when
the driver turns off the air conditioning).
If there has been no compressor on request and status ET088 remains INACTIVE (see
62A, Air conditioning).
Note:
Switching on the compressor is only authorised when the engine is running.
Switching on the compressor is ultimately controlled the UPC.

INJECTOR CODE USE
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
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.
In this case, 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).
In this case, run command SC002 Enter injector codes, applying the procedure
described in the interpretation of this command.
Status ET104 is FAULTY if the computer does not have IMA codes in the memory.
Fault DF276 Injector code programming is present and the engine runs 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 Techline.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

SYNCHRONISATION
NOTESSpecial notes:
Only perform these 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 calculate
the precise position of the cylinder's Top Dead Centre.
NOT PERFORMED
When the engine is stopped but the ignition switched on, cylinder no. 1 is no longer
indicated.
Status ET238 is NOT DONE; synchronisation between the crankshaft and the camshaft
has not been carried out.
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 DONE.
If after several attempts to start the engine, status ET238 remains NOT DONE, refer to
the interpretation of the following faults:
–DF005 Engine speed sensor circuit.
–DF097 Camshaft sensor circuit.
If the engine does still not start, consult the Customer complaints section, ALP2
Starting faults.

IMMOBILISER CODE PROGRAMMED
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
Status ET341 becomes YES if dialogue is established between the UCH and the
injection computer and the card code is recognised.
The engine is only authorised to start if the code is recognised by the UCH computer and
status ET003 Engine immobiliser is INACTIVE.
The code remains NO if dialogue between the UCH and the injection computer is not
possible. Status ET003 Engine immobiliser is ACTIVE.
The cause of the malfunction may be due to the incorrect programming of the cards,
(see 97B, Passenger compartment connection unit, configuration and
programming); follow the card programming procedure.
If the malfunction is not due to the card codes, test the multiplex network (when fault
finding is carried out for functions) and check that there is dialogue between the UCH,
the Protection and Switching Unit and the injection computer.
If dialogue is not established, contact the Techline.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.
