Default KV6 EMS2000 diagnostics working (sort of)

I have now cracked the login algorithm for the EMS2000 ECU.

So far I can read and delete error codes, and I have enough tools to do the live data but I haven't actually done it. I got far enough to know that it will get done though.

With this ECU I am also getting more codes in Rover mode than in EOBD, though it does work with an EOBD scanner.

Error codes in Rover mode:-


Error codes in EOBD mode:-


I think that it will take me a solid day to get the live data done, maybe more, and I can only do it during week days as that's when I can get access to the reference tool for this. I'll reply back when it's done.

How much of the Bosch KTS system format is being used in this Phillip?

I may have a KTS 550 kicking about somewhere if I hunt hard enough

That does make sense Phillip, as OBD2 is primarily for emissions reporting.

What do you mean by "system format"? Basically I use the KTS and sometimes a friend's SnapOn Modis to figure out what the bytes within the various packets mean.

The format of the packets was designed by Rover (or maybe BMW.. ) not Bosch or SnapOn.

I'm not sure what difference it makes which tool is used to figure it out.

It seems likely that the EMS2000 will be the same as the R75/ZT so yes.
If the Jatco protocol is the same as R75/ZT then it would by my intention to do that as well.
I am probably going to struggle to get hold of an MS43 ECU so that one seems problematic. I also assume that they are OBD2 compliant so is there going to be a big market for that?
I would like to support the Freelander ABS/Airbag ECUs as well but it will be a while. I have to work on the ECUs first that I have already committed to with people who have already paid on that basis.

I wanted to crack the live data for the EMS2000 this week before the Kickstarter campaign closes, but the person who lets me use his Modis has gone on holiday for a week so that isn't going to be possible. Hopefully I can get it done next week.

Yeah same Jatco TCM in the Freelander 1 and the 75/ZT.

The Siemens MS 43 ECU was used in the BMW E39 and BMW E46. Some neat info here: http://forum.e46fanatics.com/showthread.php?t=929951


in the Freelander the MS 43 does have OBD2 for troublecodes, but in that mode, there are very very very few PID for live data. (engine rpm temp, a few more things)

Can you do work with just an ECU by itself or you need the whole car?

Normally I can manage just with the ECU.

thanks, Philip
