View Full Version : Ibus + ipk = ...

Hello everyone,

I have one idea....read...

1. Displaying custom messages on that display (i.e. coolant temperature).

2. On the IPK (instrument cluster), you can see TrafficMaster module displaying "boot" message

http://forums.mg-rover.org/attachment.php?attachmentid=27526&d=1158253150

3. TrafficMaster module is connected to IKE through dedicated "Nav-bus" line (single wire + 12V + GND), described here:

http://forums.xpowerforums.com/showthread.php?t=34798

4. Engineer from Pektron described TrafficMaster module working like this:

The Rover traffic alert device (TAD) simply receives the RF data from the roadside beacons and sends it via the I-bus to the instrument cluster.

As far as our unit is concerned there are just the 3 wires connected, the 0 volts, ignition +12 volts and the data bus to the cluster.

The other 3 unused connections are 1 no connection, 1 battery and 1 Beep disable, none of which are necessary or normally used.

Hope that clarifies


So, I want to make an interface that would read coolant temperature from K-BUS line and send it to the IPK like TrafficMaster sends its own messages.

What I need ? I need someone who has IBUS analyzer to connect it and log the message format being sent from TM module to IPK (through pink-black wire). When we decode the format, we can try to disconnect TM and send our own messages to IPK. If we succeed in that, I can guarantee that I will make the interface that will display coolant temperature on IPK display, or any other info being transmitted on K-BUS line (speed, RPM, ...)

It's a good idea and something worth trying. I'm sure it's possible although could be difficult.

I would start by understanding how traffic master transfers the information to the ipk. Is it raw data going to the ipk and the ipk translates the data into readable text or does the trafficmaster interface translate the data and trasmit text (or perhaps something else?).

Taking apart a TM unit would be fun too.

Affaid I can't really help in any way though.

That's exactly what I need - someone to connect IBUS analyzer to the TM wire that goes into IPK and capture the data traffic.

I am sure there are people here who have IBUS analyzer and it's 10 minutes job to do it.

An interesting starfting point could be to use the following I-bus interface: http://www.reslers.de/IBUS/index.html

You can then use NavCoder software from http://www.siegenthaler.co.nz/

This will definately get you on the ibus - I have tried the demo software and it works well.

Thanks for this info, but I need TM module data to be captured. I cannot do it my self as here in Serbia we don't have any TM transmitting stations at all :(

Yes please, very interested. My guess is that the data between TM and IPK will be just standard serial ASCII data, as this is what many of the general purpose LCD displays use. I fancy the display will be just a standard one which has been adapted for use on the 75, back lit by a red or yellow LED's.

There is one perhaps minor problem, the display is also used for showing mpg/ trip mileage etc. which overides the TM's use of the display, for lighting faults, door open warnings etc.. So it is already a very heavily used display.

If data between TM and IPK is plain ASCII, it would be fantastic, but I doubt.

Display IS heavily used BUT TM displays messages when you are not in any of trip computer functions. Also, it is possible to display 4 lines of text on the display and those could contain current speed, mpg, coolant temperature and trip mileage.

Sounds good ? :)

Let's wait for ROGER with some data capturings

To avoid conjesting the ipk, would it not be better to build a small separate lcd display.

To avoid conjesting the ipk, would it not be better to build a small separate lcd display.

That idea is also good, but I want to make it "OEM-like" as much as possible. Once we figure everything out (how TM works, the format of data sent to the IPK, etc) it would be easy to display information on separate LCD.

Anyway, all ideas, proposals, advices, are more than welcome !

Currently, we are waiting for Roger to get back with TrafficMaster IBUS data capture.

I've been experimenting with an old IKE not in the car to see what I can do with it.

So far I've found the Nav-Bus messages are in I/K bus format.

Nothing I've sent has done any good (not certain it's getting there yet!)

Operating the (equivalent of) the computer button on the stalk I get from the Nav-Bus on the IKE:

Press Computer from main
22:04:41 from:F0 length:07 to:3B 43 C2 02 80 04 xx
Press Computer return to main
22:04:55 from:F0 length:07 to:3B 43 C2 02 80 01 xx
22:04:55 from:F0 length:07 to:3B 43 C2 02 80 04 xx
Then without doing anything
22:04:57 from:F0 length:07 to:3B 43 C2 02 80 02 xx
22:05:15 from:F0 length:07 to:3B 43 C2 02 80 01 xx
Then nothing more

Does this on power up
22:05:15 from:F0 length:07 to:3B 43 C2 02 80 01 xx

So clearly I/K bus format.

in the whole BMW equivelent I wonder the message centre is like a MIR???

The messages above are from F0 (BMBT) although that may be because it's a button.

About 6 hours so far and not much of use as yet, although the messages abouve could be used to operate a computer driving an replacement display placed in the IKE + show other information.

Still playing......

Great ! Finally someone who's interested to play with IKE messages :)

I tried to connect Resler's interface to TM module pink wire (which is going to IKE) and got just some rubbish in NavCoder. I will play more over the weekend and post my results, but as I said, my idea is to resolve the format of messages sent to IKE and then programm a PIC that will read coolant temp, RPMs, Speed,... from I-Bus and then send it to IKE display.

Please post all your findings

Great! I probably wont go as far as replacing the display in the IKE, so that would be useful to me too. Put up raw hex if you like and I'll have a go with it too.

If we can crack the messages to IKE on the NAV-Bus then it shouldn't be hard to read the I-Bus and format up a message to put on the Nav-Bus.

Great job ! Keep on researching and post some data captures here, I'm very keen to see it.

btw, are you using Resler's interface and NavCoder? and where are you accessing the ibus wire on the IPK (18-pin connector, pin 3 ?)

Do you guys know if the coolant temp, RPMs, Speed, MPG etc are on the iBus? Or just in the IKE?

Obviously info like RPM, speed etc get to the OBD socket. Is the format changed from the iBus to the OBD port?

I'm using Resler's interface and a bit of VB I knocked up (easiest as my car PC is currently running XP).

If you can post up the data you sniffed that would be helpful. There is a version of the Sat Nav that displays directions on the IKE and maybe this is done with bitmaps, so having the data for the TrafficMaster logo onto the Nav-Bus might unlock this.

Coolant and outside temp, Speed and RPM are definately on the I-bus (sent from the IKE). Not dug further yet,

80 06 BF 19 [Outside temp byte] [Coolant temp byte] 00 xx

80 05 BF 18 [Speed byte/2] [RPM byte/100] xx

I'm playing around with my Dynavin D99 at the moment but all I can get on the OBC screen are the outside and coolant temps - see pic below. I don't have all the readings shown in the pic - this is from a BMW.

I don't think the other info is available on our iBus e.g. voltage, tank capacity, distance to empty, MPG. Are these only on the IKE?

If I find out I'll let you know. There are a lots of messages that have not been decoded by anyone I've found on the Internet. There appear to be messages where you can request data from the IKE, so that might do what you need or maybe not, but whether you can make it work with that device is another question.

I thought that both cars had the same bus system (Ibus on the Beemer and K bus on ours) but that doesn't seem to be the case.

Does the OBD port present data in the same format as I/K buses? I might try and connect there.

No problem, I will post the data on Saturday. FYI - the wire that is used by TM module to display TM messages on IKE LCD screen is the SAME wire used by "low line" navigation to display textual navigation messages. In regard to TM logo displayed on the screen, I think IKE is "preconfigured" to display it when it gets reply from device ID of TM module (3F - same as DIAG, which is a bit confusing).

See some data below, but as was advised by Jochen (NavCoder author) I need to put 10k resistor between Ibus and 12V and try again, which I will do on Saturday :)

Sending 3B 06 F0 43 82 00 01 xx clears the display.

Changing the 01 to other numbers causes the display to show garbage. Maybe this is some kind of pointer to what data to show. Memory addresss? Page?

Pin 10 - Connector S2

Navcode can show the data, just not translate into what it means.

I was getting garbage without the 10k resistor, but I just have the USB interface, a breadboard and the IKE.

Just to be sure - You need to send the data over the Nav-Bus to get it on the display.

Later we'll need to grab data off of the I-Bus and contruct the messages to send onto the Nav-Bus. I think.

There is none - It is just data on a shared between many things, bus system wire. As I understand it, the information needed has to be requested, then the item with the data responds with the data and all on the bus.

Guessing at the way this idea is going -

A pic (a tiny stand alone microprocessor) needs to be programmed to talk to the bus, make the requests for the data you mention, accept the replies, then 'paste' the data to the IPK display. You already have the fuel consumption on the button, but voltage, a proper engine temperature, a more accurate mph/ kph all shown in the display at the same time, sounds like a possibility with the push of a single button.

I don't think it all applies, but the important bits certainly do so far.

I've pasted his post below. I think it would be polite if we don't trample over his thread over on bimmerforums.co.uk and continue here.

Thanks again RichardP!

--------------------------------------------------------------------------
I got the information by monitoring the navbus to see if it was like the iBus, it was so I had a little play.

These are the only commands I know, they are just a few notes I jotted down as I went, I'm not sure how accurate the notes are, if you have the ability to send the commands then give them a go.

There are no separate connections for all those data, they are transmitted on IBUS like coded messages.That was my understanding also but as previously said, the E46 OBD can't seem to interpret/display the codes in my car.

I might try a direct connection to the IPK.

The difference between the "now playing" and the bold version is
1B 80 01

See:
3B 14 F0 43 00 1C 00 01 00 4E 6F 77 20 50 6C 61 79 69 6E 67 00 xx

1B = Decimal 27 = Escape -> Escape sequences?????

We maybe able to just remove these for now to keep things simple. I don't think bold works on the IKE, at least not this way.

I think it would be polite if we don't trample over his thread over on bimmerforums.co.uk and continue here.That thread is mostly dead now, the OP got his mono nav working by connecting up his navbus and has wandered off :driving:

Jochen has updated navcoder to include the mono nav hex address and is looking at the commands when he gets time. be sure to update to the latest betas when hey come out :D

If you're having trouble getting anything working I can connect up my E46 Radio Nav unit and have another look at the commands, I only spent an hour or so looking previously. I derived all the commands from just looking at the way the BMW Nav displayed text and graphics.

I'll watch with interest to see how you get on and which features are supported by the Rover display. What capability does it have in standard form? Are there any pictures anywhere?

Other things that I remember, but did not write down at the time :

- You can display text starting at any pixel point X or Y axis, it's not limited to just 'lines'.
- You can draw lines from any pixel point to any other, horizontal, vertical or diagonal.
- Unless you clear the entire screen, it's very easy to end up with a total mish mash of jumbled up characters all overlayed on top of one another!

What capability does it have in standard form? Are there any pictures anywhere?As well as text, it can display graphics, such as small BMW ASC warnings and brake warnings, as well as a full screen version of same.

Also I think it displays the standard mono nav "arrows" displays. I'm not sure if these are drawn to the display or are preloaded, from what you are saying it seems the arrows (and possibly roundabouts?) may be drawn to the display. It does appear to have more lines than the mono nav display.

You've seen all my pictures on the bimmerforums thread. :(

Here's a few from Google

Possible upgrades might include to add lane guidance and distance to the next POI. This may require a map update to add the extra info about the lane, merged in from an AISEN nav.

My AISEN toyota TNS300/TNS310 "arrows" map tells me the distance to the next 3 services when I'm on the motorway, plus what they offer (fuel, loos, coffee) which is quite handy for Mrs JL, as well as lane guidance.

I mention it because the file systems seem remarkably similar on the VDO and AISEN systems and perhaps the maps and POI could be merged using and ISObuster/ISOmagic.

Unfortunately unless the iBus or Navbus is active with information about the upcoming junction then this might be restricted to displaying OBC data. I do wonder if there is an iBus to navbus bridge in the cluster.

I'm not at all familiar with the Rover dash, but in some ways it appears quite similar to the BMW 'High OBC' in that it can display information which is not important (track number, radio station name etc. on the BMW) but also information which is very important (brake failure, low oil level, etc.).

My concern with using the Rover cluster for generic information would be in ensuring that any critical warnings that the cluster display is used for are not overwritten with something else, thus masking a potentially serious problem.

In the case of the BMW High Cluster the check control system uses a different display message, this can be detected and used to prevent any overwriting of the display. A similar mechanism may be possible on the Rover display, but this would require analysis of the messages used to display the warning messages and symbols.


Also I think it displays the standard mono nav "arrows" displays. I'm not sure if these are drawn to the display or are preloaded, from what you are saying it seems the arrows (and possibly roundabouts?) may be drawn to the display. It does appear to have more lines than the mono nav display.
Even if it's a higher resolution display, it may be only addressable in at a similar resolution to the BMW Radio Nav display. If the picture posted by Leafie shows the display output of the same message that I used to display "A Hard Day's Night" on the BMW Radio Nav, then it would appear to have the same addressable resolution.

It's possible that the symbols used are held in the clusters memory and are simply displayed using some message with an icon ID, again logging the messages sent over the navbus to the cluster would give a lot more information.


You've seen all my pictures on the bimmerforums thread. :(
Indeed, but they do not show what the display is used for while in the vehicle. For example, the third picture shows what appears to be some form of break warning and traction control warning but with no text as shown in your 'googled' pictures.

The only message that I know of that the BMW Nav system gives regarding approach to a junction is only used in the E46 (maybe also in the Z4 and X3), it gives a count down in Meters or Yards to the next junction and is displayed in the low cluster display. For some reason this feature is disabled if the vehicle is identified as, for example, an E39, the message is no longer sent. I've tried several methods to re-enable it but any mechanism that I've tried causes all sorts of other problems!

I think the screen is driven in 2 ways.

1. By the instrument cluster itself that is aware of vehicle sensors by direct connection or CAN-Bus for critical information such as brakes etc and I-Bus messages for non-crital information such as door open, bulb failure etc

2. By the Nav-Bus. This allows SatNav or TrafficMaster to display information on the same screen the cluster uses, but it is "low priority" and the Rover literature states "high priority" messages will replace "low priority" ones.

So, our pretty messages will be replaced should something bad happen to the vehicle and in any case the major ones are on lamps anyway.

Unless you have TrafficMaster most of the time the screen is blank.

I'm also guessing the very first messages I posted from the Trip button presses are there to enable applications writing to the Nav-Bus to be aware of their status on the screen. e.g. in the same way you can move to the trip functions and Traffic Master. What would be a problem, I think, is having TrafficMaster and something else trying to write to the screen.

It maybe the Traffic Master Nav-Bus output could be routed into something that arbitrates for the display or there may be more than one "screen" that can be written to.

- You can display text starting at any pixel point X or Y axis, it's not limited to just 'lines'.
Done that!

- You can draw lines from any pixel point to any other, horizontal, vertical or diagonal.
Done that too! I wonder if there are other operations in there such as square, circle etc.

- Unless you clear the entire screen, it's very easy to end up with a total mish mash of jumbled up characters all overlayed on top of one another!
True. Good feature as well though as you can build a screen and display it in one hit which looks tidy. Although it's a low res display all that drawing would look pretty poor.

The icons also move about I think, with the highest priority first.

If memory serves the E39 display is MID and the E46 display is IKE (or vice versa), and for certain cars the MID moves to the dash? I must say I've never seen that countdown on my E46, could it be MK4 only?

Thre are two types of cluster in the iBus generation BMWs, High and Low.

The Low cluster has a schematic of the car to display door open and bulb out warnings.

The High cluster has a 20 character display, which is similar to part of the MID (Muti Information Display) that's used on the E38, E39 and X5 if you have anything other than the basic radio but no Nav.

You can have a MID with the Low cluster, you can even have a rear MID with Nav or another MID.

But I digress.

I can't accurately remember if the juction countdown was available with the Mk III in the E46 I had with one, it's a while ago, but I rather thought it was.

Ah yes of course, the E46 High cluster was super rare at least in England, and I had forgotten about it. :bowdown:

Hi everyone,

My 2 years old daughter caught a bad virus so we spent most of our time visiting doctors :( so I couldn't play with IKE and the interface.

Tomorrow (actually today) at 7am I'm travelling for a 2 weeks business trip to Bratislava so will not be able to contribute to this thread, but after that you have my promise that I will spend all my free time testing IKE and NavBus messages. Meanwhile I will purchase the full version of NavCoder so I will be able to SEND messages to IKE as well, can't wait to start playing :drool4:

See you all in 2 weeks, keep researching and posting your findings!

Cheers,
Milos

something new?

something new?

I think we're waiting on milosnikolic's data capture.

My guess is raster graphics can be sent to the IKE via the Nav-Bus. The displaying of the logo should confirm this. This is not essential to the original desire to display coolant temperature though.

With 2 bus interfaces it would be quite easy to read the I/K-Bus data and format a message onto the Nav-Bus, but I think we need to understand more about the interaction between TM and IKE to control when the message is displayed.

I'm hoping that the stalk button/IKE and TM message interactions will enable this to be done.

Hello!

Not heard anything from milosnikolic. Hope everything is ok.

I've being doing lots of experimenting, but working on something I want especially now my speed awareness course is booked!

I've managed to display a pic of a speed camera sign etc that I plan to hook into GPS and a camera location database to alert me to those marvelous devices.

I'll post a pic soon, but my test IKE has a big problem with display breakup at the moment.

I'm certain what milosnikolic is after can be done, although it would interfere with TM, so logs still needed.

I have a 2nd I-Bus interface on order so I can read and write both.

Hi everyone,

I'm currently on 3 weeks vacation with my family and before that I really haven't had time to experiment with Resler's interface. I plan to post logs beginning of september when I'm back.

@Leafie: What is the second IBUS interface you are waiting for ? If it can read & write I would like to order it as well.
