Check that the temperature value shown on the instrument panel display is plausible. Also check that when the NQS is switched off and switched back on again the temperature value is plausible.
Move on to Step 2
1.Irregular value not plausible.
2.The value is correct when the ignition is switched on again.

ACTIVE DIAGNOSIS CHECK
ALL OK
PROBLEMS ENCOUNTERED
ACTION
Check, using the Examiner in active diagnosis, that the autotest function is correctly activated
Move on to Step 2
The function in question is not controlled by the active diagnosis
Using the Examiner in the "Climate Control Node" ambient, check that there is no air temperature sensor error.
End of diagnosis
1.Outside air temperature sensor defective/incorrectly calibrated.
2. Wiring defective
1.Replace the sensor
2.Restore correct wiring.
The "Instrument Panel Node" receives information on the outside temperature from the "Body Computer" which, in turn, receives the figure from the sensor on the moving part of the driver's rearview mirror.
