Component Description For Keyless-Go Control Unit - GF80.61-P-4204FG

Model 213 

up to model year 2021 

Shown on model 213.0 

Location 

The KEYLESS-GO control unit is located on the right in the trunk behind the side paneling.

Task 

The KEYLESS-GO control unit has the following purposes:

• Reading in of sensors 
• Evaluation of input factors 
• Actuation of components 

Reading in of sensors 

The input factors are read in via the following connections:

• Direct line 
• KEYLESS-GO LIN (LIN B27) (with CODE 871 (HANDS-FREE ACCESS)) 
• Interior CAN (CAN B) 

Direct line 

The signals from the following components are read via direct lines:

• FM, AM, ZV, DAB and KEYLESS-GO antenna amplifier (A2/18)
• Left front KEYLESS-GO door handle (A17/1) (with CODE 889 (KEYLESS-GO))
• Right front KEYLESS-GO door handle (A17/2) (with CODE 889 (KEYLESS-GO))
• Left rear KEYLESS-GO door handle (A17/3) (with code 889 (KEYLESS-GO))
• Right rear KEYLESS-GO door handle (A17/4) (with code 889 (KEYLESS-GO))

KEYLESS-GO LIN (with CODE 871 (HANDS-FREE ACCESS)) 

The signals from the rear switching module (N38) are read in by the KEYLESS-GO LIN.

Interior CAN 

The signals are read in by the KEYLESS-GO control unit via the interior CAN.

Evaluation of input factors 

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Actuation of components 

The following components are actuated via direct lines:

• FM, AM, CL, DAB and KEYLESS-GO antenna amplifier
• Trunk KEYLESS-GO antenna (A2/35)
• Left rear door KEYLESS-GO antenna (A2/39) (with code 889 (KEYLESS-GO))
• Right rear door KEYLESS-GO antenna (A2/41) (with code 889 (KEYLESS-GO))
• Center console KEYLESS-GO antenna (A2/60)
• Wake-up line to electronic ignition lock control unit (N73)
