15 Right Seat (Passenger Seat) With Seat Heating and Seat Ventilation Components
• Seat heater and seat ventilation are not installed in all vehicles (optional equipment).
• The Climatronic control module (J255) , adjusts the seat heating and seat ventilation. The activation of the seat heating and seat ventilation is displayed in the read measured values function of the Guided Fault Finding of the Climatronic control module. Check using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
• Different control units, refer to => [ Seat Heating and Ventilation, Checking ] Seat Heating and Ventilation, Checking , and using the Vehicle Diagnostic Tester in the "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).
• For information about seat heating and ventilation, refer to => [ Seat Heating and Ventilation, Checking ] Seat Heating and Ventilation, Checking.
• 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 Passenger Memory Seat Control Module (depending on the vehicle type and the vehicle equipment level). In this vehicle information that the event memory in the relevant control module or in the comfort system central control module (J393) needs to be read out is currently not sent via the data bus to the Climatronic control module. Check using the Vehicle Diagnostic Tester in the "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.
