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

Component Identification:

General
The convenience feature includes the following functions
^ Convenience closing/opening with transmitter key
^ Convenience closing/opening via recirculated air
^ 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 and
^ 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.

On the Japanese version, this function is also possible on the front passenger door via the IR receiver unit.

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 CAN-B.
The EIS control unit checks the access authorization of the transmitter key.
If the access authorization is valid, the EIS control unit transmits the command "Convenience closing/opening" to door control units, the front SAM control unit and the overhead control panel control unit.
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

Convenience opening/closing via recirculated air button
^ 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 function, the momentary windows positions and the tilting/sliding roof position are stored

Function sequence
When the recirculated air switch on the AAC control and operating unit or comfort AAC control and operating unit is pressed for a longer time, the "Convenience closing/opening" command is transmitted to the door control units, front SAM control unit and overhead control panel control unit via CAN B bus. They then actuate the corresponding power window motor and the SR drive unit.
When the recirculated air 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 recirculated air 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)
^ Press and hold one of the door handle switches

The convenience closing function can be 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 keyless go control unit.
It relays the "Convenience closing" command to the EIS control unit via KG bus.

If the access authorization is valid, the EIS control unit transmits the command "Convenience closing" to the door control units, the front SAM control unit and the overhead control panel control unit 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.
