with Recirculation Door Motor Position Sensor (G143)

• You can check the adjustment motor's function via the "output diagnostic test mode" using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function or check it without a tester as follows: if not using a tester, connect both contacts 5 and 6 on the adjustment motor's connector to a 12 V DC source. The adjustment motor will move in one direction up until the stop, and will reverse direction if the plus and minus contacts are switched. Use an adapter cable. Refer to => [ Adapter Cable for Activating Control Motors ] Adapter Cable for Activating Control Motors.

• Perform Basic Setting of A/C system after installing a new control motor using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

• 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) using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.
