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;
