__FORCETOC__
== U102F - Fan Identification Sensor: No Communications==

==== Possible Causes ====

* Wiring, connections concerns or faulty G611-Radiator Identification Sensor

==== Possible Solutions ====

* Correct wiring, connection concerns or replace failed G611-Radiator Identification Sensor (w/radiator). 

=== Special Notes ===

* Currently, the G611-Radiator Identification Sensor is not available separately, it comes with a new radiator when ordered from the vehicle's manufacture. The sensor will need to be attached to the radiator with AMV-195-KD1-01 adhesive, See Volkswagen Tech Tip 19-12-01 for more information.

* The cooling surface of the radiator on some Volkswagen/Audi Group vehicles is coated with a catalyst that helps reduce Ozone, The G611 sensor monitors this function and is part of the federal emissions control of these vehicles which allows the manufacture to receive EPA 'credits'. 
** This this technology is called PremAir®, see the BASF web site for more information.

* Note: The fault code 'U1030-LIN bus inactive' may also be present,this should clear when the U102F fault has been corrected.
