7 Defroster Vent/Right Side Window
8 Instrument Panel Vent, Right
• Removing and installing instrument panel vents, refer to => [ Instrument Panel Vents and Rear Vents ] Instrument Panel Vents and Rear Vents.
9 Dust and Pollen Filter (With Or Without Activated Charcoal Filter Element)
• Follow the replacement intervals.
• Different versions depending on the vehicle version and equipment level.Refer to Electronic Parts Catalog (ETKA).
- Oh vehicles with the "Basis" A/C system without activated charcoal filter element
- Oh vehicles with the "Comfort" A/C system with an activated charcoal filter element There is an air quality sensor (G238) installed on these vehicles. Refer to => [ Dust and Pollen Filter with Activated Charcoal Insert ] Description and Operation.
• Removing and installing, refer to => [ Dust and Pollen Filter ] Service and Repair.
• In model year 2012, vehicles with a "Comfort" A/C system will have a modified dust and pollen filter with an activated charcoal filter element installed as a running change. This filter with an improved interception rate for fine particulates has approximately the same air resistance values as the filter installed prior to the change, and for this reason will be in installed in vehicles built up to the change. Refer to Electronic Parts Catalog (ETKA).
• If the customer requests it, it is permitted the exchange a dust and pollen filter without an activated charcoal filter element that came with the vehicle from the manufacturer for a dust and pollen filter with an activated charcoal filter element so long as the vehicle has the "Basis" A/C system. Refer to the Parts Catalog.
10 Right Front Upper Body Outlet Temperature Sensor (G386)
• Removing and installing, refer to => [ Right Front Upper Body Vent Temperature Sensor (G386) ] Right Front Upper Body Vent Temperature Sensor (G386).
• Installed only in the "Comfort" A/C system.
11 Right Condensation Water Drain (Front Passenger Side)
• Checking, removing and installing, refer to => [ Condensation Water Drain Hose ] Condensation Water Drain Hose.
12 Right Seat (Passenger Seat) With Seat Heating and Seat Ventilation Components
• Seat heating components ( Right Front Seat Temperature Sensor (G345) , Right Front Heated Seat (Z46) ) and seat ventilation (control unit and blowers).
• The seat heating and seat ventilation are not installed in all vehicles (optional equipment).
• The A/C Control Head Climatronic Control Unit (J255) adjusts the seat heating and seat ventilation. Activation of seat heater and seat ventilation are displayed in measured value block of front Climatronic Control Module, check using the Vehicle Diagnostic Tester in "Guided Fault Finding" function.
• Different control units, refer to => [ Front Seat Heating and Ventilation, Checking ] Testing and Inspection , and the Vehicle Diagnostic Tester in "Guided Fault Finding" function, activate the seat heating the seat ventilation, depending on the vehicle equipment and version. (for the Vehicle Electrical System Control Module (J519) , the Memory Seat/Steering Column Adjustment Control Module (J136) and the Passenger Memory Seat Control Module (J521) , depending on the vehicle).
• Repair the seat heating and the seat ventilation.
• For information about seat heating and seat ventilation, refer to => [ Front Seat Heating and Ventilation, Checking ] Testing and Inspection.
• If there is a condition, where the heating or ventilation of the driver of passenger seat cannot be switched on, this will be stored as a malfunction in the Vehicle Electrical System Control Module, in the Memory Seat/Steering Column Adjustment Control Module or in the Passenger Memory Seat Control Module (depending on the vehicle type and the vehicle equipment level). Currently no information is sent to the Climatronic control module via the data bus system; the DTC memory must be read out in each control unit or in the Comfort System Central Control Module (J393) using the Vehicle Diagnostic Tester under "Guided Fault Finding" function. In the event of a complaint regarding seat heating or seat ventilation, first check the event memory of the control modules activating the seat heating and seat ventilation.
• The seat heating and ventilation is adjusted by the Climatronic control module; the adjustment is transmitted to the vehicle electrical system control module (J519) via the Data bus. The target temperatures for the different seat heating and seat ventilation settings are stored in the vehicle electrical system control module. Depending on the version of the vehicle electrical system control module and on the vehicle build date, the specified temperature for the seat heating and ventilation can be different with the same setting on the Climatronic control module. Check using the Vehicle Diagnostic Tester in "Guided Fault Finding" function (for the vehicle electrical system control module).
