GF80.45-P-0003TX Convenience Feature (CF), Function

Component Identification:

General
The convenience feature (CF) includes the following functions
^ Convenience closing/opening with transmitter key
^ Comfort closing/opening via air recirculation function (except vehicles as of model year 09 /�J08 with code (494) USA version or code (460) Canada version)
^ Convenience closing via keyless go (KG) (only with code (889) Keyless Go)

All windows and the tilting/sliding roof (SR) can be closed or opened with the convenience closing/opening function

Function requirements
^ No overvoltage or undervoltage
^ All doors closed
^ No lockup recognition

Convenience closing/opening with transmitter key
^ Press "Lock or unlock" button on transmitter key for longer than 1 s while pointing at left front IR receiver.

Function sequence
When the "Lock or unlock" button on the transmitter key is actuated (longer than 1 s), it transmits the infrared "Convenience closing/opening" command to the left front IR receiver (precise aiming required)
This signal is read in by the left front door control unit and transmitted to the EIS control unit via interior CAN. The EIS control unit checks the access authorization of the transmitter key.
If the access authorization is valid, the EIS control unit transmits the "Convenience closing/opening" command to the door control units and overhead control panel control unit via interior CAN. They then actuate the corresponding power window motor and the SR drive unit.

When the "Lock or unlock" button is released the convenience opening/closing of the power window motors and SR drive unit is terminated immediately.

Comfort closing/opening via air recirculation function (except vehicles as of model year 09 /�J08 with code (494) USA version or code (460) Canada version)
^ Actuate recirculated air switch on AAC control and operating unit or on comfort AAC control and operating unit.

The convenience opening feature with recirculated air is accomplished only when previously closed with convenience closing via recirculated air. When closing with convenience feature, the momentary window positions and the tilting/sliding roof position are stored.

Function sequence
When the air recirculation switch on the AAC [KLA] control and operating unit or on the comfort AAC control and operating unit is pressed for a longer period of time.

The "Comfort closing/opening" command is transmitted to the door control units and overhead control panel control unit via interior CAN. They then actuate the corresponding power window motor and the SR drive unit. When the air recirculation switch is pressed again the corresponding power window motors and the SR drive unit are automatically moved to the positions before the convenience opening/closing function.

When the air recirculation switch is actuated again, the convenience opening/closing of the power window motors and the SR drive unit is stopped immediately.

Convenience closing via Keyless Go (KG) (with code (889) Keyless Go)
^ Press and hold one of the door handle switches

The convenience closing function can only be accomplished via the door handle switch.

Function sequence
When the corresponding door handle switch is actuated for a longer time it transmits the "Convenience closing" command to the corresponding keyless go control unit
It transmits the command "Comfort closing" to the EIS control unit via the Keyless-Go data bus (KG-bus).
If the access authorization is valid, the EIS control unit transmits the "Convenience closing" command to the door control units and overhead control panel control unit via the interior CAN.
They then actuate the corresponding power window motor and the SR drive unit.

By pulling the door handle, closing of the windows and closing of the tilting/sliding roof is terminated.
The power window motors and the SR drive unit are actuated in the opening direction for approx. 2 s.
