Fault finding - Conformity check62B
MAIN SCREEN
NOTESOnly carry out this conformity check after a full check using the diagnostic tool
(fault reading and configuration checks).
Application conditions: engine stopped with ignition on (12 V APC), AIR
CONDITIONING OFF (air conditioning compressor not activated).
Note:
This page lists the statuses and parameters provided by the climate control computer
but which are not associated with the three sub-functions given in the conformity
check (PASSENGER COMPARTMENT VENTILATION, COLD LOOP and HEATING
sub-functions).

Fault finding - Interpretation of statuses

ET141
PASSENGER COMPARTMENT FAN
NOTESSpecial note:
This status is used by the UCH to authorise the request for air conditioning which is
sent to the injection. The UCH sends this signal to the injection to authorise the
request to activate the passenger compartment heating resistors (only on diesel
version): operating safety.
This status shows the operation of the passenger compartment blower.
When the passenger compartment blower is operating (from speed 1 to speed 8), the status displays: RUNNING.
When the passenger compartment blower is not operating (speed 0), the status displays STOPPED.
If the status does not operate as displayed, check that the passenger compartment blower is operating correctly.
If the passenger compartment blower does not work, apply the fault finding procedure in Fault finding chart
(ALP) 5 No passenger compartment ventilation.
If the passenger compartment blower operates correctly but the status displays the message OFF, check that the
passenger compartment blower visual feedback (spiral symbol) on the control panel works correctly (increase in
spiral bargraphs according to the eight speeds).
If the passenger compartment visual feedback (blade symbol) on the instrument panel does not work, contact
your Techline.
If the fault is still present, perform fault finding on the multiplex network (see 88B, Multiplexing).
AFTER REPAIRRepeat the conformity check from the start.

PR122
NIGHT LIGHTING LEVEL
NOTESThe climate control computer receives the dimmer lighting level via the instrument
panel through the multiplex line.
This parameter indicates the dimmer lighting level as a percentage.
If this parameter appears inconsistent with the air conditioning control panel lighting, contact Techline.
AFTER REPAIRRepeat the conformity check from the start.

Diagnostic - Fault finding chart62B
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.
