Is there a fault with the distribution of air?
NO
Is there a fault with the flow of air?
NO
Is the heating insufficient?
NO
Check that the air recirculation flap does not remain closed when in the recirculation position. On the diagnostic
tool, status ET062 RECIRCULATION FLAP POSITION should show OPEN (the flap can be seen by removing
the windscreen frame).
Repair if necessary (apply the fault finding procedure for fault DF021 RECIRCULATION MOTOR CIRCUIT).
Is the fault still present?
YES NO
Carry out a conformity check on the temperature
sensors (interior, exterior and coolant
temperatures). Replace any faulty components.YESSee ALP 2, Air distribution fault.

Using the diagnostic tool statuses and parameters
screen (cold loop sub-function), check that the
temperature signals are consistent (no sensor
deviation resulting in incorrect measurement).
–Using parameters PR002
"exterior temperature", PR064
"coolant temperature" and PR001
"interior temperature".
Are the temperature signals consistent?
YES
Start the engine and switch on the air conditioning
by pressing the AC button (with a request for
maximum cold temperature and the passenger
compartment blower running).
Display the following status in the “User selection”
sub-function screen:
ET140 "air conditioning request" should be
ACTIVE and the “AC” symbol should be displayed
on the air conditioning control panel screen.
Is status ET140 ACTIVE?
YES
NOCarry out a conformity check:
–For the coolant temperature sensor,
see 13B, Diesel injection, Fault
summary table or 17B Petrol
injection, Fault summary table.
–For the exterior temperature sensor,
see 87B, Passenger compartment
connection unit, Fault summary
table.
–For the interior temperature sensor,
see 62B, Climate control, Fault
summary table.
Replace any faulty components.
NOAir conditioning request interpretation fault
on the climate control computer. Carry out
fault finding on the climate control
computer (see interpretation of
statuses).
AFTER REPAIRCarry out a complete check with the diagnostic tool.

With the engine warm and passenger compartment
ventilation operating, vary the position of the mixing
flap from the maximum cold position to the
maximum hot position and check subjectively that
there is a difference in temperature.
Is a difference in temperature noted?
YES
Using the diagnostic tool statuses and parameters
screen (cold loop sub-function), check that the
temperature signals are consistent (no sensor
deviation resulting in incorrect measurement).
–Using parameters PR002 Exterior temperature,
PR064 Coolant temperature and PR001
Interior temperature.
Are the temperature signals consistent?
YES
Check the refrigerant fluid (see Technical Note
6001A, Air conditioning, 62A, Air conditioning,
Air conditioning: Check).
NOCarry out a conformity check on the
mixing motor (PR012 Mixing flap
position). If the conformity check does
not reveal any faults, look for a
mechanical fault on the mixing flap
(condition of the motor ’s notched sector,
flap jammed inside the unit, etc.).
NOCarry out a conformity check:
–For the coolant temperature sensor, see
13B, Diesel injection, Fault summary
table or 17B Petrol injection, Fault
summary table.
–For the exterior temperature sensor,
see 87B, Passenger compartment
connection unit, Fault summary
table.
–For the interior temperature sensor, see
62B, Climate control, Fault summary
table.
Replace any faulty components.
AFTER REPAIRCarry out a complete check with the diagnostic tool.

ALP 13 Lighting fault on the control panel in night mode
NOTESOnly consult this customer complaint after a complete check of the multiplex
network and the air conditioning with the diagnostic tool.
Special notes:
With the ignition on, the control panel screen is permanently on but the panel buttons
only light up when the side lights are switched on.
Note:
If the exterior temperature sensor is faulty, the climate control computer is
activated 5 seconds after the ignition is switched on (the UCH performs fault
finding on the exterior temperature sensor).
Use the Wiring Diagram Technical Note for the New Twingo.
Is the fault shared with other components (first row cigarette lighter, radio, multifunction display, cruise control/
speed limiter on off switch, etc.)
YES NO
Switch on the ignition and the side lights.
Using the diagnostic tool and the conformity
check, check that the lighting dimmer is operating
correctly using parameter PR122 NIGHT TIME
LIGHTING LEVEL.
Does the parameter vary?
YES
Check the connection and condition of the
connector of component 419.
If there is a repair method (see Technical Note
6015A, Electrical wiring repair, Wiring: Repair
precautions), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
NOCarry out a fault finding procedure of the
instrument panel.
Run a multiplex network test (see 88B,
Multiplex).
AFTER REPAIRCarry out a complete check with the diagnostic tool.
