A/C System Control and Regulation Components Inside Passenger Compartment

• If there is a malfunction in the system, first check the Climatronic control module (J255) DTC memory. Refer to Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

• If no fault is displayed, read the measured value block for the Climatronic control module (J255) and activate the component with the "output diagnosis test mode" function on the Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

• The electrical test for various actuators, potentiometers and sensors is described in Guided Fault Finding using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

• Servicing operations on refrigerant circuit are described in=> [ Refrigerant Circuit, Servicing ] Refrigerant Circuit, Servicing.

• Perform the following work after completion of repair operations:

- 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.

- Check coding of Climatronic control module using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

- If necessary, check adaptation of the Climatronic control module using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

- Perform A/C system basic setting using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.
