GF80.61-P-2009TA Unlocking, Function
- with CODE (889) Keyless Go

Component Identification:

Unlock
Requirements:
^ Circuit 30

Possible control elements for system activation:
^ Pulling door handle
^ Pulling rear-end door handle (A12/1)

Function sequence using driver's door as example

1. Actuate left door handle switch (S17/19) by slightly pulling on driver's door handle (t >0.1 s).

The keyless go system is waked up.

2. A wake-up signal is transmitted to the remote control key (A8/1).

3. The locating signals are transmitted from the keyless go trunk antenna (A2/35), to the rear bumper antenna (A2/31), the left rear keyless go door control module (N69/8), the right rear keyless go door control module (N69/9) and the passenger compartment keyless go control module (N103).

The remote control key (A8/1) determines its position in relation to the vehicle.

4. The position of the remote control key (A8/1) is transmitted via the right antenna amplifier module (A2/65) to the rear module keyless go control module (N102).
5. Checking rear module keyless go control module (N102) according to valid remote control key (A8/1).
6. Transmitting access authorization code to EIS control module (N73).
7. If the access authorization code is correct the signal "CL opening" is stored on the CAN class B bus.
8. Parallel to this the "Actuate opening assist" signal is transmitted to the left rear door keyless go control module (N69/8) by the EIS control module (N73). The left front opening assist motor (M57) is actuated (the rotary tumbler of the door lock is unlocked and the door opens slightly).

The actuation of the central locking depends on the adjustment of the remote control key (A8/1).

Possible settings:
^ Global unlocking
^ Selective unlocking (control point driver's door: selective unlocking Other control point: global unlocking)

Function sequence shown using rear-end door as example
1. Pull rear-end door handle (A12/1).
The signal is read in by the rear-end door control module (N111) and transmitted to the rear module keyless go control module (N102) via the EIS control module (N73).

2 to 6. See "Function sequence using driver's door as example

7. If the access authorization code is correct the EIS control module (N73) actuates the rear-end door CL motor via the rear-end door control module (N111).

Doors and tank flap remain locked.
