COMPUTER + AFTER IGNITION FEED
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
ABSENT ignition on
Check the condition and conformity of the F5D (5A) supply fuse for the UPC.
Repair if necessary.
Check for the presence of an earth on the following connections:
Injection computer black 32-track connector A, track G4 battery earth
Injection computer black 32-track connector A, track H4 battery earth
Injection computer black 32-track connector A, track H1 battery earth
Repair if necessary.
Check for + 12 V on trackD1 of connector A of the injection computer.
If there is no voltage, check the continuity and insulation against earth of the following
connection:
Injection computer black 32-track connector A, track D1 Track 1 UPC black
connector
Repair if necessary.
PRESENT ignition on
Check that there is not + 12 V with the ignition switched on trackD1 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
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
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.
The status ET004 remains at NO" in 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 at NO then the air conditioning should be authorised, check:
– that the air conditioning compressor is activated correctly,
– the air conditioning system feed fuses,
– for gas in the air conditioning circuit,
– the gas pressure value is consistent at idle speed.
If the fault is still present, check the air conditioning computer for faults (See 62A, Air
conditioning).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.
