You can either use the Resler’s I-Bus interface ( Click Here for integration instructions), or a USB to TTL serial converter along with the TH3122 Arduino interface ( Click Here for integration instructions).As some of you may be aware SK93 and a few of us have suggested a seperate area on the forum for Coding. To use NavCoder, you must find a way to connect the I/K-Bus to your laptop. I have collected several documents from various sources that contain many examples of I/K-Bus messages – these can all be found on my resources & downloads page (Under the “K-Bus Structure” folder).Īnalyzing the bus for specific messages is very easy by using the NavCoder software. The receiver will compare that value with its own computation, and if not equal, will reject the packet. The XOR checksum byte is used to check the integrity of the message. Summary of transmitted information (check sum) Detailed description of message (maximum 32 bytes of data)ĥ. Receiver address (8 bit Destination ID)Ĥ. Length of data (number of following message bytes)ģ. The information sent over the bus is configured serially. Every 30 seconds after Terminal R is switched on, each module on the bus line is polled. The modules polled are according to the coding of the Master Controller.

The LCM/LSZ is the Stand-by Controller.Įach module on the I/K-Bus is informed by a message from the Master Controller as to the ready status of all of the other connected modules.

The GM is the Master Controller for vehicles equipped with only the K-Bus.

On E46, E52 and E39/E53 Base version vehicles:

The GM is the Main (master) Controller of the K-Bus.

The IKE and MID/BMBT are Stand-by Controllers.

The LCM is the Main (master) Controller of the I-Bus.

On E38 and E39/E53 High version vehicles: If the bus line is quiet for more than 60 seconds, all of the control modules will go into Sleep Mode.Ĭontrol units that provide the I/K-Bus operating voltage (Master controllers) are: (9600, 8E1).Īny device can start sending when the bus is idle, but if it discovers that the line is pulled low without doing it itself, it has to abort. The I/K-Bus is always active when terminal R (Ignition) is switched on. Serial communications on the bus are 9.6Kbps, 8 data bits, Even parity, and 1 stop bit. This is the reverse of many digital signals where the normal voltage is 0V and is raised high (Vmax which in this case is Vbatt or +12v) to send a bit. The bus’ physical layer is an open collector setup – pulled high (+12v) by the bus and pulled low by the talker. This means that the normal voltage on the wire while the bus is idle is +12V (the battery voltage, or Vbatt). A bit is transmitted by pulling low or shorting the bus with the ground momentarily. – MRS, Multiple-restraint system (Airbag module)

Most of the information in this article comes directly from the PDF files in the resources & downloads section (Under the “K-Bus Structure” and “Resources” folders). Both of these bus systems are technically identical, the only difference is their use by model. From this point forward they will be referred to as the I/K-Bus and differences will be pointed out separately. Models without Navigation or IKE will use the K-Bus only. The K-Bus was added to the E38 along with the I-Bus. With the introduction of the E38, the I-Bus is now referred to as the instrumentation bus. The E31 version of the I-Bus was used for body electronics and driver information systems. The I-Bus is known as the “Instrumentation-Bus” and the K-Bus is the “Karosserie-Bus” – Karosserie is German for “Body”. Initially the I-Bus was introduced on the E31 as the information bus. The I/K buses handle information/multimedia peripherals. Since the K-bus has available only one single line yet it transmits data in both directions, data are transmitted in half-duplex mode – it is possible to only transmit or receive at any one time. In other words, it is a way for devices within the car to communicate with each other. The K-bus is a serial communications bus in which all connected control units can send as well as receive information over a single wire. The K-Bus is a standard bus protocol for BMW car electronics. *** Project: Arduino & BMW K/I-Bus Interface ***
