Test AE: Outside Air Temp Display Does Not Operate Correctly (Base Instrument Cluster Without EATC)

Pinpoint Test AE: The Outside Air Temperature Display Does Not Operate Correctly (Base Instrument Cluster without Electronic Automatic Temperature Control)









Normal Operation
The outside air temperature sensor is hardwired to the instrument cluster through circuits VH407 (YE/GN) and RMC32 (GN/BU). The message center displays the outside air temperature upon receipt of the outside air temperature data.

Possible Causes
- circuit VH407 (YE/GN) open or short to ground
- circuit RMC32 (GN/BU) open
- ambient air temperature sensor
- instrument cluster
