CC.0 : Short circuit to earth
CO.1 : Short circuit or open circuit to + 12 V
NOTESConditions for applying the fault finding procedure to stored faults:
Apply this fault finding procedure if the fault appears as present or stored again after:
–switching on the ignition and switching on the climate control.
Special notes:
The internal temperature sensor (linked to a micro-turbine, depending on vehicle
equipment) is located at the top of the roof in the unit underneath the rear view mirror.
Check the connection and condition of the internal temperature sensor connector.
Replace the connector if necessary.
With the ignition on ("forced" + after ignition: see Introduction), check that the temperature sensor micro-
turbine is working correctly.
If it is not working, check for the presence of +12 V on track 1 of the temperature sensor connector and an
earth on track 3.
If the micro-turbine supply is correct and the micro-turbine does not operate, replace the component: sensors
+ micro-turbine (the micro-turbine is not available as a separate part).
Disconnect connector A (12-track) from the climate control computer in order to check the insulation,
continuity and absence of interference resistance on the connections:
Computer connector A track 5 Track 4 of the internal temperature sensor
Computer connector A track 12 Track 5 of the internal temperature sensor
Track 1 of the solar radiation sensor
Repair if necessary.
Check the resistance value of the sensor between:
track 4 and track 5 of the internal temperature sensor connector. Replace the sensor if the resistance is not:
10 kΩΩ Ω Ω

±± ± ±
500 ΩΩ Ω Ω
at 25˚C (for more details, refer to the electrical specifications of the sensor according to
temperature in the Help section).
If the fault is still present, replace the internal temperature sensor.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline): reconfigure the
computer (see section Configurations and Programming).
Deal with any other faults.

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 at high speed.
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 shown, refer to ALP 10 in Section 62A Air conditioning.
AFTER REPAIRRepeat the conformity check from the start.

HEATED REAR SCREEN: MANUAL MODE
NOTESNone.
This status specifies whether 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 timed period depends on the exterior temperature (approximately 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 operation of the heated rear screen is requested in manual mode, the status should display: ACTIVE.
If operation of the heated rear screen is not requested, the status should display: INACTIVE.
If the status does not operate as shown, refer to ALP 10 in Section 62A Air conditioning.
AFTER REPAIRRepeat the conformity check from the start.
