SITUATION
The Service Engine Soon (MIL) lamp is on with either of the following DME faults stored:
^ E-Series: 2F99 - ambient temperature sensor, plausibility
^ F-Series: 10B008 - ambient temperature sensor, plausibility: signal implausible
The fault could occur if the vehicle is exposed to high temperature fluctuations.
For example:
The vehicle is parked for several hours in a heated garage. The engine is started and then driven outside of the garage during the cold time of year.
CAUSE
DME diagnostic software
CORRECTION
If the fault is stored, proceed as follows based upon the DMEs current software or vehicle integration level.
