BMW Night Camera
Dear Sir, a question: I have a camera FLIR BMW Night Vision and I would like to install it on other cars. I can not make it work because I think it is locked. I think I understand that some of you (user Alcain?) able to make it work and I would ask you to give me some info and advice. There are accessories to unlock this camera ?
The camera I bought from a scrap car recovery but did not know the block and I've probably wasted my money (although few). I want to use only the cables +12 v:-12v and video to build a Night Vision on another car. I hope I can help and advise you how to act. I do not know if it's the version 1 or 2, but if I answer then I can send pictures of the camera with the scriptures BMW. Can you answer my PM?? Thank you for your kindness and patience. I use a translator for the English language and I apologize for any errors Sincerely ... Alfredo (Italy) My email: alsulas@alice.it |

I think this thread is the "bible" of E90 canbus hacking, together with the work done by Trevor Cook in his site http://www.loopybunny.co.uk/CarPC/k_can.html Neither me and Trevor suceeded in making the driver window to move through sending messages in canbus (ID 0x0FA) but only on passenger side (ID 0x0FB). The logic behind between the two seems the same, but actually there must be something different somewhere. Maybe Highvoltage or Efunroom were able to do that. Any clue to help? Thanks! |

Going ahead to sniff the Kcan-bus of my E92 2007, I discovered that by writing the following message to the bus:
ID:2A0 LEN:8 DATA:88 88 80 0 16 40 86 0 I've been able to open the trunk. Hope this is helpful for somebody. |

IBus
I know this is an old thread, but I have been searching for some answers to some fundamental questions and cant seem to find the answers, this is the best option
I have seen many websites selling an IBus usb adapter. I am struggling to find out what exactly that means, the IBus, because I don't see specific mention of in this thread. The answer can be just as simple as it is a generic name for the overall bus system in the BMW, I can accept that. As a newbie I have this initial question that I am struggling to place an answer. Follow up questions include is it associated with a specific model, etc... I have a 2011 335i xDrive manual sedan that I am looking to tap into the electronic system, climate, radio, windows, etc... kinda stuck on this initial component. Thanks in advance for the extra knowledge and getting me started... Keith |

just wanted to share some of my experiences...
Steering wheel buttons on a 2006 330i Message ID 1D6 Message is length 2 (DLC = 2) Every second : C0 0C is broadcast If a button is pressed it is broadcast at 10Hz (every 100ms) Byte0 Byte1 UP: E0 0C Down: D0 0C Source: C0 4C Recirculate: C0 1C Voice:C0 0D Phone: C1 0C Vol+:C8 0C Vol-: C4 0C I spliced into the K-CAN at the back of the HVAC control module on the black connector. This is a easy place to access the bus. Here's a picture of my splice without the back-shell of the connector. View post on imgur.com I currently have a beaglebone black setup to listen for these messages and then relay track changes to my android phone. Here's the code repository for my project. Its still a work in progress but it works. https://github.com/SquidIndustries/AndroidCarAudioDock |

hello,
Does anyone have information about how to send a "key position 1" or "ignition on" signal on k-can? I would like to test an E90 CCC+CID on the bench. If i send the following messages the navi only start for 1 sec. (Continuous data transmission with can analyzer) CAN ID:26E Data:00 40 7F 50 FF FF FF FF ID:130 data:45 40 21 8F FE Thanks! |

has anyone figured out the idrive knob CAN ID ? It seems that some are getting 1B8 on older models but i'm not getting an IB8 IDs when reading kcan from behind the head unit.

Instrument cluster display
Hi All,
Super glad I found this thread, you all have saved me a ton of work building a steering wheel CAN to BT for phone control. One thing of interest is there was some mentioning of attempts to display information on the radio or instrument cluster over CAN. Has anyone had any luck with this or aware of any one who has done it? It has certainly been done before even on oldies like the E34, although drastic architectural differences exist. I've been scouring the internet and feel that the unfortunate answer is that its likely not possible for the instrument cluster and it would need to be through the CD changer input for the radio. I'm making this assumption based on the fact that it seems the Radio doesnt have the ability to send playback metadata for the instrument cluster. Anyways thought I would check in here and see if any of you have thought about this as well and perhaps come to a similar conclusion or not. Cheers, Tyler |

And I don't think that it is possible to draw your information on display via CAN bus. You need MOST bus for it. IMHO |

I tried the demo inside this pack with no luck.
I'm using a Sparkfun can bus shield and Arduino uno with a OBD II to DB9 cable. Code:
#include <LCD05.h> #include <Canbus.h> int data; char buffer[456]; //Data will be temporarily stored to this buffer before being written to the file LCD05 lcd; void setup(){ Serial.begin(9600); lcd.backlightOn(); lcd.hideCursor(); lcd.brightness(80); lcd.clearScreen(); if(Canbus.init(CANSPEED_100)) /* Initialise MCP2515 CAN controller at the specified speed */ { Serial.println("CAN Init ok"); } else { Serial.println("Can't init CAN"); } delay(5000); lcd.clearScreen(); } void loop(){ Canbus.ecu_req(ENGINE_RPM, buffer); lcd.setCursor(1,1); Serial.print("RPM: "); Serial.println(buffer); Canbus.ecu_req(ENGINE_COOLANT_TEMP, buffer); lcd.setCursor(2,1); Serial.print("Temp: "); Serial.println(buffer); delay(500); } Inside canbus.h I found: #define ENGINE_COOLANT_TEMP 0x05 #define ENGINE_RPM 0x0C |

I don't have CAN-H CAN-L as I can see, since pins 6 and 14 are missing. I have only K-Line. On the OBD II plug I have pins 1,4,5,7,9 and 16. I read TrevorC was able to get information from K-Line. |

E90 KOMBI
Hi,
I have managed to send the 0x130 (every 100ms) and 0x26E (every 200ms) messages to wake up the KOMBI. However, it is doing some kind of reset since it is continuously beeping and flashing error lights. In fact, when I send the RPM message of 1500RPM, the needle goes from 0 to 1500, back to 0 and again to 1500 repetitively. I am trying to make the KOMBI pretend that it is in a real car with its engine running i.e. displaying the time and odometer. Maybe the KOMBI is waiting for some specific messages other than the 0x130 and 0x26E. Does anyone have this problem, please? If yes, how did you managed to solve it, please? Thanks, Robert |

Where does the KCan signal start from?
I'm trying to locate a KCan comms fault and had an idea of adding my own twisted pair cable and start adding modules one by one as a test and process of elimination Which KCan modules are a must to connect at first? Kombi and JBE? |

By far the easiest place to tap into CAN is behind FRM.
Just above foot rest there is a thick bundle of wires. PT-CAN and K-CAN are spliced there from factory. Wires are twisted together and all you have to do is remove the plastic insulation. Bear in mind that there is more things splined there. What you need, are twisted wire pairs with colors as in the picture. I run those wires to OBD2 connector. I added pins and I am reading DCAN, PTCAN and KCAN using comma.ai Panda. Also, I started openDBC repository for E-series that can be used in Cabana. I wonder if E8x CAN is the same as E9x...

I know this is an old thread, but seems like my best shot at finding knowledge!
I have an e90, I've assembled a CAN interface using arduino UNO and a DFRobot CANBUS shield, I've loaded a basic config to it just to test receiving can messages... My problem is, as soon as the CAN H & L on the shield are connected into the CAN H & L in the car, (behind the stereo, i-drive controller or junction box behind gloves box) the car triggers an electronics failure error? Does this sound like it could be a faulty CAN shield? Thanks in advance, Tim |
