Convenience feature (CF), function (MODEL 204.0/2 up to Model Year 08/Modification Year 07) - GF80.45-P-0003CW

MODEL 204.0/2 up to Model Year 08/Modification Year 07 

General information 

The convenience feature allows to centrally open or close the windows and the tilting/sliding roof (with code (414) electric glass tilting/sliding roof) or panoramic roof (with code (413) panoramic glass sunroof with top sliding sunroof) from various control points.

The convenience feature allows the following subfunctions: 

Convenience feature via transmitter key 

Function requirements 

IMPORTANT The status of the circuit is stored by the electronic ignition lock control unit (N73) on the interior CAN. The status of the doors is read in by the left front door control unit (N69/1), right front door control unit (N69/2), left rear door control unit (N69/3) or right rear door control unit (N69/4) and is transmitted to the interior CAN.

Function sequence for convenience feature via transmitter key 

Actuate and hold lock or unlock button on transmitter key for t > 2 s while aiming transmitter key at infrared remote control receiver on driver side front door (A26/1). The signal is received by the infrared receiver and relayed to the left front door control unit. It transmits the signal via the interior CAN to the following control units:

at a time offset of t = 80 ms.

IMPORTANT On vehicles with panoramic roof, the roller sun blind is opened before the panoramic sunroof is opened with the convenience feature. The panoramic sunroof is opened only after a new opening request.

With convenience closing, the roller sun blind is actuated only after the panoramic sunroof is closed completely or when a new request is present.

For this purpose the panoramic sliding roof control unit (A98) actuates the panoramic sliding roof roller sun blind drive unit (M12/5).

Convenience feature via air recirculation function 

Function requirements 

Function sequence for convenience closing via air recirculation function 

Actuate air recirculation button (N22/7s2) on automatic air conditioning control and operating unit (N22/7) for longer than t = 1.5 s to actuate convenience feature

The automatic air conditioning control and operating unit then transmits the signal "Convenience closing" via the interior CAN to the following control units:

The control units store the corresponding position of the windows and the roof.

Then

with a time offset of t = 80 ms.

Function sequence for convenience opening via air recirculation function 

Actuate air recirculation button on automatic air conditioning control and operating unit for longer than t = 1 s to actuate convenience opening.

The automatic air conditioning control and operating unit then transmits the signal "Convenience opening" via the interior CAN to the following control units:

Then

at a time offset of t = 80 ms to position stored before convenience closing.

Convenience feature via Keyless Go 

Function requirements 

Function sequence for convenience feature via Keyless Go 

If one of the comfort sensors on the outside of the KEYLESS-GO door handle is touched for longer than t = 2 s, the Keyless-Go control unit (N69/5) transmits the signal "Convenience closing" via the interior CAN to the following control units:

Then

with a time offset of t = 80 ms.

IMPORTANT On vehicles with panoramic roof, the roller sun blind is opened before the panoramic sunroof is opened with the convenience feature. The panoramic sunroof is opened only after a new opening request.

With convenience closing, the roller sun blind is actuated only after the panoramic sunroof is closed completely or when a new request is present.

For this purpose the panoramic sliding roof control unit actuates the panoramic sliding roof roller sun blind drive unit.

Convenience closing is interrupted in the following cases:

If the same KEYLESS-GO door handle is pulled during comfort closing, or max. t = 2 s thereafter, emergency opening is activated. In this case, the windows, the tilting/sliding roof or the panoramic sliding roof are actuated in the opening direction. Actuation is performed for min. t = 2 s or as long as the KEYLESS-GO door handle is pulled, max. t = 90 s.
