NOTESConditions for applying the fault finding procedure to stored faults
The fault is considered present when the engine is running.
Special notes:
The heating and air conditioning system request is not longer possible.
The compressor is still active, risk of irreparable damage to the compressor (loss of
capacity). The customer is complaining that the air conditioning is operating
continuously.
See Technical Note Wiring Diagrams of the vehicle concerned
Check the connection and condition of the injection computer connector, component code 120.
Check the connection and condition of the air conditioning compressor relay connector, component code 5845.
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run command AC180 Air conditioning compressor relay control.
If the command does not work, check, with the ignition on, for +12 V on connection 3FB of component 584 and
for earth on connection 38K of component 584.
Check the insulation and continuity of the following connections:
–38K between components 584 and 120,
–3FB between components 584 and 238.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, run fault finding on the climate control computer (see 62B, Climate control).
If the fault is still present, check the relay and replace it if necessary.
If the fault is still present, contact the Techline.

–313 (10A) (Modus and Clio III),
–F5D (5A) (Mégane II and Scénic II),
–F9 (15A) (New Twingo)
Use a multimeter to check for a + 12 V feed on the fuse holder with the ignition on.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the continuity and insulation against earth of the following connection:
–AP15 between components 1337 and 120
–AP29 between components 1337 and 120 (for New Twingo)
Check for continuity and the absence of interference resistance on the following connection:
–N between the earth and component 120 (for Kangoo 2),
–NH between the earth and component 120 (for Modus, Clio III and New Twingo),
–M between the earth and component 120 (for Mégane II and Scénic II).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
"PRESENT"
NOTESIgnition on
Normal operating condition:
Check, using a multimeter, the absence of a + 12 V ignition off on the connection AP15 or AP29 of component 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.

ET007PRE-POSTHEATING UNIT CONTROL
STATUS DEFINITIONACTIVE: the status is active when the heater plugs are activated according to the
engine coolant temperature.
INACTIVE: the status is inactive after the engine has been running for a certain period.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit control
circuit.
Conformity check: Engine running and the engine coolant temperature > 80˚C
ACTIVEWhen the ignition is switched on, status ET007 should be ACTIVE for a time that varies
according to the engine coolant temperature. Both the relay and the heater plugs are
supplied.
After starting the status should remain ACTIVE for a time that varies depending on the
engine coolant temperature. This is postheating.
If ET007 is INACTIVE when the ignition is switched on, check:
–The supply fuse FB1 (70A) of the engine fuse and relay box or F2 (70A) on the power
feed fuse board, according to the vehicle.
–The feed to the heater plugs following relay actuation, and the heater plugs
connections.
–The continuity and the absence of interference resistance between the following
connections:
●Connection code 37Z between components 257 (or 980) and 680.
●Connection code 37AA between components 257 (or 980) and 681.
●Connection code 37AB between components 257 (or 980) and 682.
●Connection code 37AC between components 257 (or 980) and 683.
–That the contacts of the pre-postheating unit connector are in good condition and
connected correctly.
If the vehicle starts, preheating is completed and status ET007 remains ACTIVE during
the engine operating phase, consult the interpretation of faults DF017 Preheating unit
control circuit and DF025 Preheating unit fault finding connection.
INACTIVEIf the vehicle does not start, the status remains INACTIVE and the preheating was not
executed when the ignition was switched on or during the starting phase, check the
following connections:
●connection code 3FY and 3FF between components 120 and 257 (or 980).
Check for + 12 V on the preheating unit.
●Connection code BP35 of component 257 (or 980).
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
