TEMPERATURE DISPLAY
NOTESSpecial notes:
Check that the vehicle is equipped with an external temperature sensor.
IMPORTANT
This command lasts approximately 30 seconds.
It makes it possible to check the connection between the display (component code 653) and the UCH
(component code 645).
With the command running, the temperature display should change; if not apply the fault finding procedure below.
Read configuration LC002 External
temperature sensor.
Is the configuration “With”?
YES
Check that LC067 "External temperature display" is "WITH". Otherwise
perform CF171 "Temperature display".
Check the condition and connection of the PE2 40-track UCH connector,
(component code 645) (tabs bent, broken, etc.).
If the connector is faulty and there is a repair method (see Technical Note
6015A, Repairing electrical wiring, Wiring: Precautions for repair),
repair the wiring, otherwise replace the wiring.
Check the continuity of the following connection:
Connection code 47Z between components 645 and 653.
If the connection is faulty and there is a repair procedure (see Technical
Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),

If the connection is correct, replace the display (component code 653)
(see MR 86A, Radio, Display: Removal - Refitting).
If the fault is still present, contact Techline.
NOIf the vehicle is fitted with an external
temperature sensor, check that the
configuration CF029 “External
temperature sensor” displays “With”.
If the vehicle is not fitted with an external
temperature sensor, it is normal that the
external temperature is not displayed.
