CLIMATE CONTROL
Fault finding - Configuration and programming
CLIMATE CONTROL COMPUTER CONFIGURATION
The climate control computer has three configuration functions. These configurations need to be set after replacing
the computer.
These three configurations are important as they ensure that climate control is optimised within the vehicle (better
control compared to automatic air conditioning). If these configurations are not entered correctly, cold air and warm
air production will be severely affected.
These configurations can be accessed in repair mode by the diagnostic tool and can only be entered using
the fault finding by computer menu as opposed to the fault finding by function menu.
These configurations can also be read using the diagnostic tool in repair mode to ensure they have been correctly
set. Configurations can be read in fault finding by computer mode and fault finding by function mode.

WARNING
–The "ZONE 1" configuration must be selected for HOT AND HUMID COUNTRIES which correspond to the
technical and legislative criteria available on the Shared World Information.
–The "ZONE 2" configuration must be selected for TEMPERATE COUNTRIES which correspond to the
technical and legislative criteria available on the Shared World Information.
Note:
In hot and humid climates, when the heating and air conditioning system is in operation, condensation
may form on the outside of the windscreen.
The "ZONE 1" configuration corrects this customer complaint.
Note:
In fault finding by function mode, the diagnostic tool can also display the configuration readings of the other
computers involved in the air conditioning function. All of the air conditioning function configurations (of the
injection computer and UCH computer) are listed (See 62C, Air conditioning).

ET085
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.

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.

PR012
MIXER FLAP POSITION
NOTESNone
The mixer flap moves according to the temperature requested or automatically if the climate control is in
automatic mode. The mixing motor does not have a position copy potentiometer. This parameter is therefore an
indication of the flap position according to how the motor is being controlled by the climate control computer. As
specified in the conformity check, in the “maximum cold” position (15 ˚C) the parameter indicates 0 % and in the
“maximum hot” position (27 ˚C) the parameter indicates 100 %.
If the value displayed by this parameter appears inconsistent or if the parameter is consistent but the temperature
of the blown air does not change in accordance with the user's request: apply the fault finding procedure for fault
DF010 "Mixing motor circuit" or consult the fault finding charts ALP 6 No heating or ALP 8 No cold air
depending on the customer complaint.
AFTER REPAIRRepeat the conformity check from the start.
