Solar Sunroof Operation, Checking

• In vehicles with the "sunroof with solar cells" option (introduction not yet finalized), the Fresh Air Blower (V2) is activated by the Fresh Air Blower Control Module (J126) when the ignition is switched off. => Vehicle Diagnosis, Testing and Information System VAS 5051 in the "Guided Fault Finding" function.

• Depending on the adaptation of the Climatronic Control Module (J255) A/C control head, the "solar operation" function can be switched off via the MMI (Multi Media Interface - the control modules exchange information via the comfort data bus system). => Vehicle Diagnosis, Testing and Information System VAS 5051 in the "Guided Fault Finding" function.

• Depending on the adaptation of the Climatronic Control Module (J255) A/C control head, the "solar operation" function is switched off by the Fresh Air Blower Control Module (J126) when the ambient temperature is low. (the control modules exchange information via the "Lin Bus" data bus system of the A/C system) => Vehicle Diagnosis, Testing and Information System VAS 5051.

• For example, the solar operating time for the Fresh Air Blower (J126) is displayed in hours in the Climatronic Control Module (J255) A/C control head measured value block => Vehicle Diagnosis, Testing and Information System VAS 5051 in the "Guided Fault Finding" function.

• Check the sunroof with solar cells => [ Solar Sunroof Function ] Solar Sunroof Function and => Vehicle Diagnosis, Testing and Information System VAS 5051 in the "Guided Fault Finding" function.
