MODEL 906.611/613/631/633/635/637/653/655/657/711/713/731/733/735 with CODE (FY9) Keyless entry+slide with CODE (T56) Electrical actuation for left sliding door
Location
The Keyless Entry control unit is located in the driver seat frame in the left front direction of travel.
Task
After a valid transmitter key (A8/1) is recognized, the command to unlock the driver door or to open the right or left electric load compartment sliding door (E-LST) is transmitted via the Controller Area Network bus, class B (interior) (CAN B).
For this purpose, the Keyless Entry control unit must receive a signal via one of the following antennas:
- Keyless Entry right sliding door antenna (A2/101)
- Keyless Entry left sliding door antenna (A2/102)
- Keyless Entry driver door antenna (A2/103)
- Keyless Entry front passenger door antenna (A2/104)
- Keyless Entry load compartment antenna 1 (A2/105)
- Keyless Entry load compartment antenna 2 (A2/106)
On models 906.611/631/711/731 the Keyless Entry load compartment antenna 2 is omitted
The Keyless Entry control unit communicates with the EIS control unit (N73) and transmits the following messages via CAN B, e.g.:
- "STR_AUF_KE (open right sliding door)"
- "STR_SCHL_KE (close right sliding door)"
- "SEL_ENTRI_KE (selective unlocking)"
- "ID_GEBER_KE (result ID sensor search)"
- "GLOBAL_VERRI_KE (lock vehicle globally)"
- "STL_AUF_KE (open left sliding door)"
- "STL_SCHL_KE (close left sliding door)"
- "KE_DEAKTIV_ZEIT (KE deactivated by timeout)"
These messages are relayed to the corresponding control units such as:
- Driver door control unit (N69/1)
- Right sliding door [STR] control unit (N69/6)
- Left sliding door [STL] control unit (N69/7)
