Central Air Door Motor (V70)/(V145)

Central Air Door Motor (V70)/(V145)

with Central Door Motor Position Sensor (G112)

• Depending on the version of the Climatronic control module (J255) , the Central Air Door Motor (with Central Door Motor Position Sensor (G112) ) may be designated as Front Air Distribution Motor (V145) (with Front Air Distribution Motor Position Sensor (G470) ) in On Board Diagnostic (OBD).

• 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 volt 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 a basic setting to the A/C (heating) system after installing a new 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.

Removing

- Remove instrument panel (central tube remains installed).

- Reach through opening between left side of A/C unit and central tube (instrument panel cross member) and disconnect connector - A -.






- Mark connector - A - if necessary (to rule out an interchange in the event several connectors are disconnected at the same time).

- Remove bolts - B -.

- Remove control motor - C -.

Installing

- Insert stub - D - into socket - E -.

Reinstall all removed components in the opposite sequence while observing the following:

- Install the wiring harness so that it cannot come in contact with any moving parts (e.g. the actuating arm of the control motor).

- Check Climatronic control module (J255) DTC memory and erase any possible displayed malfunctions using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

- Perform a basic setting and output diagnostic test on the A/C (heater) and check the DTC memory one more time. Refer to Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.
