3 Series E46 323Ci (M52TU) COUPE
In the E60, the K-CAN S and K-CAN P from the E65, E66 have been combined to form the K-CAN.
This means the E60 has the following buses: byteflight (until 09/2005), K-CAN, MOST, F-CAN, PT-CAN plus a local
CAN (for the engine management system).
The central interface for exchanging data between buses is the safety and gateway module (SGM).
Note: Modifications in the bus structures on the E60, E61, E63, E64 from 03/2007
From March 2007, the bus structures are modified as follows:
-
The D-CAN is now also integrated:
D-CAN (diagnosis-on CAN) supersedes the previous diagnosis interface in all parts of the world.
-
The GWS is now also integrated:
A new control unit has been integrated on the PT-CAN for selecting the drive position in the automatic
transmission.
GWS: Gear selector switch
With the gear selector switch, the automatic transmission is no longer actuated mechanically, but rather
electronically.
-
The TLC is now also integrated:
A new control unit has been integrated on the PT-CAN for the driver assistance system.
TLC: Track lane control
Track lane control supports the driver by vibrating the steering wheel to warn him if the vehicle
unexpectedly drifts off of the regular course, prompting him to countersteer.
-
The LDM and LRR are also integrated:
With the introduction of active cruise control with stop&go function, 2 new control unit are integrated for
cruise control:
LDM: Longitudinal dynamics management
LRR: Long range sensor
The control unit for longitudinal dynamics management (LDM control unit) is connected to the PT-CAN.
The long range sensor is connected to the LDM and the close-range sensors by the new sub-bus. The
sub-bus is called the sensor CAN (S-CAN).

Note: Modifications in the bus structures on the E60, E61, E63, E64 from 09/2005
From September 2005, the bus structures are modified as follows:
-
No byteflight data bus
The SZL control unit is connected to the PT-CAN and no longer to the byteflight.
As before, the SZL control unit is connected to the F-CAN.
Following control units are dropped together with the byteflight:
•
SBSL: B-pillar satellite, left
•
SBSR: B-pillar satellite, right
•
TMBF: Door module, front-passenger
•
TMFA: Door module, driver
-
ACSM is added.
The crash safety system is controlled by a new control unit:
ACSM: crash safety module
The ACSM control unit is on the K-CAN.
