EXTERNAL TEMPERATURE
NOTESOnly apply the checks if the parameter is inconsistent.
Special notes:
Check that LC002 "External temperature sensor" is "WITH". Otherwise perform
CF029 "External temperature sensor".
Check that LC067 "External temperature display" is "WITH". Otherwise perform
CF171 "External temperature display".
Note:
If the exterior temperature sensor (component code 245) is disconnected or the vehicle is not equipped with an
exterior temperature sensor, the temperature displayed is the default temperature of 215 ˚C.
Check the 12-track temperature sensor connector, (component code 245) (tabs bent, oxidised, broken, etc.).
Check the PE2 40-track connector of the UCH, component code 645 (tabs bent, oxidised, broken).
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 insulation, continuity and the absence of interference resistance on the following connections:
●Connection code 47D between components 240 (for left-hand drive vehicles) or 239 (for right-hand drive
vehicles) and 645.
●Connection code 47C between components 240 (for left-hand drive vehicles) or 239 (for right-hand drive
vehicles) and 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Measure the resistance of the connector sensor disconnected from connections 47C and 47D.

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.).
