KEYLESS-GO, function - GF80.61-P-0005LE
MODEL 216.3, 221.0 /1 with CODE (889) KEYLESS-GO as of model year 2009 /YoM 08
KEYLESS-GO (KG), general
The KEYLESS-GO system allows access to the vehicle and starting the vehicle engine without using the transmitter key (A8/1). It is sufficient to just carry the transmitter key
Operation of the central locking (CL) via the transmitter key remains possible parallel to the KEYLESS-GO functions.
The anti-theft alarm system (ATA) (with code (551) Anti-theft alarm system (ATA)) functions in the same manner as when locking/unlocking the CL with the transmitter key.
The KEYLESS-GO system comprises the following partial functions:
- Function sequence for position definition of transmitter key
The following partial functions are described in separated documents:
- Locking/unlocking, function
- Engine start/stop, function
Function sequence for position determination of transmitter key (on model 216)
A position determination of the transmitter key is required for the individual functions. When the
- Trunk KEYLESS-GO antenna (A2/35),
- Left door KEYLESS-GO antenna (A2/39),
- Right door KEYLESS-GO antenna (A2/41),
- Center console KEYLESS-GO antenna (A2/60) and
- Interior compartment KEYLESS-GO antenna (A2/61) (up to 31.8.10).
are activated by the KEYLESS-GO system, the transmitter key can determine the area (A, B, C, D or E) in which it is located.
Function sequence for position determination of transmitter key (on model 221)
A position determination of the transmitter key is required for the individual functions. When the
- Trunk KEYLESS-GO antenna (A2/35),
- Left rear door KEYLESS-GO antenna (A2/39),
- Right rear door KEYLESS-GO antenna (A2/41),
- Center console KEYLESS-GO antenna (A2/60) and
- Interior compartment KEYLESS-GO antenna (A2/61) (up to 31.8.10)
are activated by the KEYLESS-GO system, the transmitter key can determine the area (A, B, C, D or E) in which it is located.
The determined position is transmitted by the transmitter key via radio signal. The rear window antenna amplifier module (A2/12) edits the signal and relays it to the KEYLESS-GO control unit (N69/5).
