Unlock, function - GF80.61-P-2009SM

MODEL 220, 215 as of 1.10.02 

Unlock 

Requirements:

• Circuit 30

Possible control elements for system activation: 

• Reach into one of the door handles
• Pull door handle

Function sequence using driver's door as example 

1. Actuate left front door pull contact microswitch (S47s1) or left front door capacitive sensor (S47b1) by lightly pulling door handle on driver's door (t >0.1 s).

   The keyless go system is woken up.

2. The keyless go system (N69/5) transmits a signal to the transmitter key (A8/1) via the left front door keyless go antenna (A2/38)

   The position of the transmitter key (A8/1) in relation to the vehicle is determined via various antennas Remote control keys in the vehicle or in the trunk are ignored

3. The transmitter key (A8/1) transmits its authorization This authorization is received by the HF antenna and is relayed to the keyless go control module (N69/5) via the overhead control panel control module (N70)
4. The keyless go control module (N69/5) checks whether the transmitter key (A8/1) is authorized for the vehicle
5. Transmit access authorization code to EIS control module (N73).
6. If access authorization code is correct, the signal "Open CL "is stored on the CAN B bus.
7. Parallel to this, the EIS control module (N73) transmits the signal "Actuate lift solenoid" to the keyless go door control module (N69/5) The left front door keyless go lift solenoid (L12) is actuated (The lift solenoid is only actuated at the control point)

All door locks are equipped for quick unlocking with lift solenoid.

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

Possible settings:

• Global unlocking
• Selective unlocking

Control point, driver's door: Selective unlocking

Control point, other door: Global unlocking

Function sequence using trunk lid as an example 

Requirements:

• Circuit 30
• The trunk is not locked mechanically (90° switch)

1. Actuate trunk lid keyless go button (S62/21) The signal is relayed to the keyless go control module by the pneumatic control unit (combined) (A37).
2. The keyless go control module (N69/5) requests the transmitter key (A8/1) to transmit its authorization via the rear bumper keyless go antenna (A2/31).

   The position of the transmitter key (A8/1) in relation to the vehicle is determined via various antennas Remote control key in the vehicle or in the trunk are ignored

3. This authorization is received by the HF antenna and is relayed to the keyless go control module (N69/5) via the overhead control panel control module (N70)
4. The keyless go control module (N69/5) checks whether the transmitter key (A8/1) is authorized for the vehicle
5. Transmitting access authorization code to EIS control module (N73).
6. If the access authorization code is correct, the signal "Remote trunk release "is stored on the CAN B bus by the EIS control module (N73) and received by the pneumatic control unit (combined) (A37).
7. The pneumatic control module with combined functions (A37) opens the trunk lid pneumatically.

Only the trunk lid is unlocked, door and filler cap remain locked.

The anti-theft alarm (ATA) behaves in the same way as if the car is unlocked and locked with the transmitter key (A8/1).
