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.

or
INACTIVEIf the brake lights are working:
–check the continuity and make sure there is no interference resistance on the
following connection:
●connection code 5A,
between components 160 and 120/645/119.
If there is a repair method (See Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the brake lights are not operational, check:
–the condition and fitting of the brake switch,
–the condition and conformity of the brake lights fuse,
–the conformity of the values in the following table:
disconnect the switch and carry out the following checks:
for MEGANE II and SCENIC II with ESP:

PREHEATING UNIT
NOTESThis command is only carried out if the fault DF025 Preheating unit fault finding
connection, or DF017 Preheating unit control circuit is present or stored and if no
other fault is present.
Refer to the Wiring diagrams Technical Note for the vehicle to locate the fuses and
relays concerned.
Connect the diagnostic tool and turn on the ignition.
With the preheating unit connected:
–connect the negative terminal of the voltmeter to track 8 of the preheating unit,
–connect the positive terminal of the voltmeter to the + 12 V battery,
–run command AC001 Preheating unit.
if the voltmeter does not indicate the battery voltage while the command is running (ten 1 second ON/OFF cycles):
1Check the condition of the preheating unit supply fuse F01 (70A).
Replace it if necessary.
2Check the following connections for continuity and the absence of interference resistance:
Injection computer connector C track E2 track 8 of the preheating unit connector
Injection computer connector C track A4 Track 3 of the preheating unit connector
Repair if necessary.
3Check the connections on the pre-postheating unit, heater plugs and injection computer.
Repair if necessary.
4Measure the resistance of the heater plugs. If this resistance is greater than 2 Ω replace the faulty plug(s).
5Check the continuity and absence of interference resistance between:
preheating unit track 1 cylinder 3 heater plug
preheating unit track 2 cylinder 1 heater plug
preheating unit track 6 cylinder 4 heater plug
preheating unit track 7 cylinder 2 heater plug.
6Then check for + 12 V supply on track 4 of the preheating relay connector.
If the fault is still present, replace the preheating unit.

Fault finding – Fault Finding Chart
ALP1 No dialogue with engine management computer
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty.
Check the battery voltage and make the necessary adjustments to obtain a correct voltage (9.5 V < Battery
voltage < 17.5 V).
If the tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the cause
could be a faulty computer interfering on the multiplex network.
disconnect the engine management computer.
try to establish dialogue with another computer.
if the fault is still present, reconnect the computer and proceed by elimination by successively disconnecting all the
following computers (according to wiring diagram and equipment): air conditioning, airbag, abs and esp, uch,
instrument panel, central communication unit, proximity sensor.
Try to establish dialogue after disconnecting each line:
if, after a disconnection, you manage to establish dialogue, perform the fault finding procedure for the relevant
computer.
perform fault finding on the multiplex network using the diagnostic tool.
Check for the presence and the condition of the injection fuses on the UPC, and/or the engine fuse box.
check the connection of the computer connectors and the condition of its connections.
Check the injection computer earths (quality, oxidation, earth bolts secure on the battery terminal).
Check that the supply to the computer is correct:
Earth on tracks H1, G4 and H4 of black 32-track connector A.
+ after ignition feed on track D1 of black 32 track connector A.
Check that the power supply to the diagnostic socket is correct:
+ before ignition feed on track 16.
+ after ignition feed on track 1.
Earth on tracks 4 and 5.
If dialogue has still not been established after these checks, contact the techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
