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:- http://www.pscan.eu/images/ems2000codes.jpg Error codes in EOBD mode:- http://www.pscan.eu/images/ems2000eobdcodes.jpg 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. |

I may have a KTS 550 kicking about somewhere if I hunt hard enough ;) Brian :D |
That does make sense Phillip, as OBD2 is primarily for emissions reporting.

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. |
What are the chances of supporting the Freelander 1 KV6 too ?
ECU: Siemens EMS 2000 (Rest of the World) Siemens MS43 (North American Automatic TCM: Jatco JF506E ABS ECU: TEVES ATE MK20 TEVES ATE MK25 |

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? |
