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.
