- with CODE (889) Keyless Go

Component Identification:

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

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 with the following connections:
^ Direct line
^ Interior CAN

Direct line

The following components are read in via a direct line:
- Left KEYLESS-GO sensor unit (B67/1) (model 216)
- Left front KEYLESS-GO sensor unit (B67/1) (model 221)
- Right KEYLESS-GO sensor unit (B67/2) (model 216)
- Right front KEYLESS-GO sensor unit (B67/2) (model 221)
- Left rear Keyless-Go sensor unit (B67/3) (model 221)
- Right rear Keyless-Go sensor unit (B67/4) (model 221)
- Rear window antenna amplifier module (A2/12)

Interior CAN
The following sensors are read in via the interior CAN:

by the EZS control unit (N73)
- Keyless-Go start/stop pushbutton (S2/3)
by the rear SAM control unit with fuse and relay module (N10/2):
- Trunk lid external operation switch (S88/8)
by the ESP control unit (N47-5) via the central gateway control unit (N93):
- Stop light switch (S9/1)
by the instrument cluster (A1) via the central gateway control unit:
- Vehicle speed signal

by the TCL control unit (N121) (model 221 with code (881) Remote trunk closing (RTC), model 216)
- TLC [HDS] button (S62/26)

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 components are actuated with the following connections:
