+ 12 V SIDE LIGHTS FEED
NOTESNone
This status indicates the presence of + 12 V side lights feed on connection LPD of component 419.
If ET002 displays ABSENT when the side light are lit, check for + 12 V between connection LPD and the earth
connection NAM of component 419.
If + 12 V is present on connection LPD and ET002 displays ABSENT.
If the status does not operate, carry out fault finding on the UCH (see 87B, UCH).
If + 12 V is not present on connection LPD, consult ALP No. 13.

COMPRESSOR CONTROL
NOTESNone
This indicates the status of the compressor actuated by the injection computer.
If ET020 displays ACTIVE, the compressor activation request is authorised.
If ET020 displays INACTIVE, the compressor activation request is not authorised.
If the “AC” indicator light is lit and if ET020 displays INACTIVE, run fault finding on the injection computer
(see 13B, Diesel injection or 17B, Petrol injection) and UCH (see 87B, UCH).

RECIRCULATION FLAP POSITION
NOTESSpecial notes
In extreme temperatures (above 35 ˚C) and when the climate control is switched on,
the recirculation flap sets itself to the recirculation position in order to correct the
passenger compartment temperature more quickly.
This status specifies the position of the recirculation flap.
If the flap is in the exterior air position, the status displays OPEN.
If the flap is in the recirculation position, the status displays CLOSED.
If the status does not operate as indicated, apply the interpretation of fault DF021 Recirculation motor circuit.

+ 12 V AFTER IGNITION PRESENT
NOTESUse the Wiring Diagram Technical Note for the New Twingo.
This status indicates activation of + 12 V APC by the UCH via the multiplex line.
When the ignition is off, the status displays ABSENT.
When the ignition is on, the status displays PRESENT.
If the status does not operate, carry out fault finding on the UCH (see 87B, UCH).

HEATED REAR SCREEN: AUTO MODE
NOTESNone
This status specifies whether the heated rear screen is operated in automatic mode or not. This mode
corresponds to the SEE CLEAR function. This function switches on the heated rear screen, the heated door
mirrors, the air conditioning and the windscreen ventilation. The heating and air conditioning system requires a
short amount of time between the request and blower activation in order for dry air to be blown. The heated rear
screen will operate for as long as the SEE CLEAR function is requested (permanently controlled). This automatic
mode is obtained by pressing the de-icing button at the top of the air conditioning control panel.
If the SEE CLEAR function is requested, the status should display ACTIVE.
If the SEE CLEAR function is not requested, the status should display INACTIVE.
If the status does not operate as indicated (see ALP10 Poor de-icing efficiency - rear screen demisting).
AFTER REPAIRRepeat the conformity check from the start.

HEATED REAR SCREEN: MANUAL MODE
NOTESNone
This status specifies whether the request for the heated rear screen is being operated in manual mode. This mode
corresponds to a timed operating period for the heated rear screen, controlled by the UCH. This time delay
depends on the exterior temperature (between 10 and 15 minutes).
Operation in manual mode is obtained by pressing the de-icing button at the bottom of the air conditioning control
panel. This function is used to switch on the heated rear screen and the heated door mirrors.
If activation of the heated rear screen is requested in manual mode, the status should display ACTIVE.
If activation of the heated rear screen is not requested, the status should display: INACTIVE.
If the status does not operate as indicated (see ALP10 Poor de-icing efficiency - rear screen demisting).

AIR CONDITIONING REQUEST
NOTESNote:
For more information, refer to the flowchart for the request to switch on the
compressor (see Air conditioning, General operating mode).
This status specifies whether the request to switch on the compressor has been sent by the climate control
computer to the UCH or not.
When activation of the air conditioning is requested, the status should display ACTIVE.
When activation of the air conditioning is not requested, the status should display INACTIVE.
If the status does not operate as indicated, contact your Techline.

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.
