With the connector disconnected, measure the resistance value of the mixing motor:
Check the resistance of component 420 between the following connections:
●connections S and 38LG,
●connections S and 38LC,
●connections S and 38LH,
●connections S and 38LD.
If the connection or connections are faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
The results of the four checks should be 100 ΩΩ Ω Ω

±± ± ±

5 ΩΩ Ω Ω
at 20 ˚C, replace the mixing motor if this is not the case.
If the fault is still present, remove the mixing motor but leave it electrically connected and send a motor command
from the temperature buttons on the control panel: switch the temperature setting to maximum 27 ˚C (a value
of 100 %), then switch the temperature setting to minimum 15 ˚C (a value of 0 %), the motor must change from
one direction to the other. If the connections are correct but the motor does not switch during the commands:
replace the mixing motor.
AFTER REPAIRClear the stored faults.
Follow the instructions to confirm repair.
If the motor has been replaced (see Configuration and programming).
Deal with any other faults.

at 20 ˚C, replace the distribution motor if this is not the case.
If the fault is still present, remove the distribution motor but leave it electrically connected, send a motor command
from the distribution buttons on the control panel: switch the distribution setting to demisting (a value of 100 %),
then switch the distribution setting to air vent (a value of 0 %), the motor must change from one direction to the
other. If the connections tested earlier match but the motor does not switch during the commands, replace the
distribution motor.
If the commands have been executed correctly, check that the distribution motor flap is not blocked by trying to
move the gears. Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the stored faults.
Follow the instructions to confirm repair.
If the motor has been replaced (see Configuration and programming).
Deal with any other faults.

Remove the distribution motor but leave it
electrically connected, send a motor command from
the distribution buttons on the control panel: switch
the distribution flap to the demisting position
(a value of 100 %), then switch the distribution
setting to vent (a value of 0 %).
Is the distribution motor operating?
YES
Visually check that when the distribution flaps are
moved manually (by turning the centre of the
control), moving the control does in fact move the
distribution flaps.
Is movement possible?
YES

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.
