Fault finding - Replacement of components
REPLACING THE CLIMATE CONTROL COMPUTER
–Note the computer configuration according to the optional equipment fitted on the vehicle (see climate control
computer configuration) or using the Shared World Information (ICM).
–Ensure that the ignition is switched off.
–After approval from the Techline, replace the computer.
–Switch on the ignition and carry out a check using the diagnostic tool.
–Configure the computer according to the vehicle specifications.
–Switch off the ignition and then back on for the configurations to register.
–Check in the Read configuration menu that the configurations have been recognised correctly.
–Check for faults and apply the corresponding fault finding procedure for any faults shown on the diagnostic tool.
–Clear any stored faults.
–Run command VP001 Enter VIN.
–Start the engine, switch on the air conditioning and ensure that it is operating correctly. WARNING
Before replacing the climate control computer, check that it is faulty (read faults, conformity of variables,
read customer complaints). Replacement of the computer must be authorised by the Techline after a fault
finding log has been completed and submitted.

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).

MIXING AND DISTRIBUTION MOTOR PROGRAMMING PROCEDURE:
There is no specific programming operation for the air mixing motor or the distribution motor.
However, the minimum and maximum limits of these motors have to be programmed. This operation is automatic
and is performed in the following cases:
–after communication using the diagnostic tool, the next time ignition is switched on,
–if a fault, declared as present when the ignition was switched off, disappears the next time the ignition is switched
on.
WARNING
It is imperative that communication is established with the diagnostic tool (to initiate programming the
next time the ignition is switched on) after any operation on the distribution and mixing motors or on the
control panel.

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.
