NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
ABSENT
NOTESIgnition on
Check the condition and conformity of supply fuse F5D (5A) of the Protection and Switching Unit.
Repair if necessary.
Check for an earth on the following connections:
Injection computer black, 32-track connector A,
Track G4Battery earth
Injection computer black 32-track connector A,
Track H4Battery earth
Injection computer black 32-track connector A,
Track H1Battery earth
Repair if necessary.
Check for + 12 V on track D1 of connector A of the injection computer.
If there is no voltage, check the continuity and insulation to earth of the following connection:
Injection computer black 32-track connector A,
track D1Track 1 of the UPC black connector
Repair if necessary.
PRESENT
NOTESIgnition on
Check that there is not a + 12 V with ignition switched off on track D1 of connector A of the injection computer.
Repair if necessary.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

AC AUTHORISED
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
The air conditioning authorisation only changes to YES if:
–the air conditioning request has been made by the driver (air conditioning switch in
AC or AUTO position with minimum ventilation),
–the engine is not under full load,
–the air conditioning system is not faulty.
Status ET004 remains at NO under the following conditions:
–Vehicle stopped with the ignition on,
–faults present in the air conditioning circuit,
–no air conditioning request made by the driver,
–engine under full load.
If status ET004 remains NO then the air conditioning should be authorised; check:
–that the air conditioning compressor is activated correctly,
–the air conditioning system supply fuses,
–the presence of refrigerant in the air conditioning circuit,
–that the refrigerant fluid pressure value is consistent at idle speed.
If the fault is still present, check the climate control computer faults (see 62C, Air
conditioning).
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

PREHEATING UNIT CONTROL
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
When the vehicle is started from cold, the injection computer controls the pre-
postheating unit so that the vehicle can be started.
Status ET007 becomes YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 becomes YES, check:
–the F2 (70A) supply fuse on the preheating unit, located on the power supply fuse
plate in the engine connection unit, below the Protection and Switching Unit,
–the resistance of the heater plugs.
Replace any plug whose resistance is not below 2 Ω.
If the vehicle starts and status ET007 remains YES during the engine operating phase,
refer to the interpretation of faults:
–DF017 Preheating relay control circuit.
–DF025 Preheating unit diagnostic connection.
After the engine is started and the preheating phase, the injection computer should stop
the pre-postheating unit operating.
Status ET007 should become NO.
In the event that the vehicle does not start and status ET007 remains NO, check the
continuity and absence of interference resistance of the following connections:
Injection computer Track A4 grey
32-track connector CTrack 9 preheating unit
Injection computer Track E2 grey
32-track connector CTrack 8 preheating unit
Repair if necessary.
If the fault is still present, refer to the interpretation of faults:
–DF017 Preheating relay control circuit.
–DF025 Preheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

CHECK COOLING FAN 1
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOTE:
Status ET014 test and status ET022 GMV1 low speed request change their status at the same time.
RUNNING
The low-speed engine fan unit is supplied in three scenarios:
–the engine coolant temperature is above 89 ˚C;
–the air conditioning is operating
–the injection computer has system faults that could lead to the engine overheating.
When the low-speed engine fan is supplied:
–status ET014 GMV 1 test becomes RUNNING status ET022 Low speed GMV
request becomes ACTIVE.
If the low speed GMV does not work (see 87G, engine compartment connection unit).
The low-speed engine fan assembly stops when:
–the engine coolant temperature is below 89 ˚C;
–the air conditioning is not switched on by the driver.
STOPPED
IMPORTANTWARNING
If the UPC does not detect the injection computer frames, the low speed engine
fan is supplied until the battery is completely discharged.
In the event that the low-speed engine fan assembly is faulty, the high-speed
engine fan assembly will then be activated.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

RUNNING
The engine fan assembly can be supplied when:
–the engine coolant temperature is above 99 ˚C.
–the injection computer has system faults that could lead to the engine overheating.
When the high speed fan is supplied:
–status ET015 GMV 2 test becomes RUNNING and status ET021 High speed GMV
request becomes ACTIVE.
The high-speed engine fan assembly stops when:
–the engine coolant temperature is below 99 ˚C;
IMPORTANTWARNING
