NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition is switched off and back on.
Note:
If the exterior temperature sensor is disconnected or the vehicle is not equipped with
an exterior temperature sensor, the temperature displayed is the default temperature
of 215 ˚C.
Check whether the right-hand door mirror is fitted with an exterior temperature sensor. (See MR 411 mechanical
systems 62A, Air conditioning, Air conditioning: List and location of components).
If the vehicle is fitted with an exterior temperature sensor, deal with the following fault finding procedure.
If NO, the vehicle is not fitted with this:
Check that the vehicle is configured without external temperature sensor (component code 240 for left-hand
drive vehicles) or (component code 239 for right-hand drive vehicles):
Check that LC002 "External temperature sensor" is "WITHOUT". Otherwise perform CF029 "External
temperature sensor".
Check the temperature sensor 2-track connector (bent, oxidised, broken tabs).

If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
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.
