‹› The function of the positioning motor can be checked, e.g. via " Output diagnostic test mode" function Vehicle Diagnosis, Testing and Information
System VAS 5051 under "Guided Fault Finding" or without a tester: To test without a tester, connect both terminals "5" and " 6" in control motor
connector to 12 V (DC), the motor moves in one direction until stop, the direction of rotation changes by interchanging B+ and Ground. Use an
adapter cable. Refer to => [ Adapter Cable for Activating Control Motors ] See: Description and Operation/Adapter Cable for Activating Control
Motors.
‹› Perform a basic setting to the A/C (heating) system after installing a new motor Vehicle Diagnosis, Testing and Information System VAS 5051
under "Guided Fault Finding".
‹› Using the functions "Output diagnostic test mode" and " Basic setting", the activation of A/C system electrical components can be tested if
necessary (e.g. allocation test) Vehicle Diagnosis, Testing and Information System VAS 5051 under "Guided Fault Finding"
‹› On the Audi TT with A/C system, both motors for left and right temperature doors are controlled via one characteristics curve, depending on the
programmed end stops (only one temperature setting on the Climatronic Control Module (J255) A/C control head is possible).
‹› Depending on the measured temperatures, the calculated sunlight intensity and setting on Climatronic Control Module (J255) A/C control head,
the calculated specified outflow temperature and therefore, the specified position of the positioning motor, may be different for the left and right
side.
‹› On the Audi TT with heater (without A/C system), only one temperature door motor is installed. Both temperature doors for the left and right sides
are connected via a shaft and moved together by the Left Temperature Door Motor (V158).
