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 running, AIR CONDITIONING ON (air conditioning 
compressor activated).
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).

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).
AFTER REPAIRRepeat the conformity check from the start.

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.
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.

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.

PASSENGER COMPARTMENT BLOWER UNIT
NOTESNone
This command is used to ensure that the passenger compartment blower is working. When this command is run 
the passenger compartment blower comes on.
If the command does not operate as indicated, consult Fault finding chart 5 No passenger compartment 
ventilation.
AFTER REPAIRCheck that the air conditioning function operates correctly.

RECIRCULATION MOTOR: EXTERIOR AIR
RECIRCULATION MOTOR: RECIRCULATION
NOTESWARNING
Do not touch the flap when running the command.
NOTE
The flap is located behind the cabin filter.
This command is used to actuate the air recirculation motor to check that it is working.
When running command AC003, the flap closes. When running command AC002, the flap opens.
If the command does not work as shown, check the mechanical condition of the flap.
If the fault is still present, apply the interpretation of fault DF021 Recirculation motor circuit.
AFTER REPAIRCheck that the air conditioning function operates correctly.

NOTESNOTES:
The flap is located in the air conditioning mechanism.
In order to confirm this command, the engine must be warm in order to be able to 
check for the presence of a warm air flow during command AC005.
This command is used to activate the mixing flap to check that it is working. Switch on the ignition, and issue a 
passenger compartment ventilation request (via the driver's control panel).
Run command AC004 and check that the air coming out of the air vents is cold (ambient temperature).
Run command AC005 and check that the air coming out of the air vents is warm.
If the command does not operate as indicated, consult the customer complaints:
–Production of cold air, see: ALP 8 No cold air and ALP 9 Too much cold air.
–Production of warm air, see: ALP 6 No heating or loss of heating.
AFTER REPAIRCheck that the air conditioning function operates correctly.
