You only must to modify the ELS27 if you want to use the media can bus. |
|
Check photo. Description says 3-12 11-13: wrong, and photo shows 6-13, 12-14: wrong because you connect canbus and mm canbus into the car obd, dangerous!). |
|
No. "Normal" CAN-Bus is on 6+14 (unmodified). |
|
Sorry, i mean that zmiterm bridge 6-13 and 12-14 and use it out the car. See green red cables in the photo and compare position with generic OBD pinout photo. If you connect els27 like this, you shortcircuit canbus and mm canbus into the car. |
|
I tried many combinations but no success. Even i disconnect obd socket side and main board connections and made many more combinations according to ford and renault pin out diagrams but all fail. I never read succesfull story. does really anyone use els27 with any renault ? I already asked to zmiterm on drive2.ru no answer. I believe els27 may fake ??? I contact russian seller of original els27 he said 75 usd but he did not know about cable modification for renault. He said original els27 will work with renault. I am not sure and waiting to read success story with els27 and renault. |
|
Clone els27 works with canbus, but NO with MM canbus. Tested by me with cedric. We need to know how ELS27 switch between canbus/mmcanbus (soft-controlled?) |
|
Simple second virtual COM on USB? |
|
I already mail latest ddt4all v.3.4.5 program with mar2018 database to cedric to check ;) download link on drive2.ru site by zmiterm. My els27 may damage during combination try :)) never connected or it was fake because i tried it without cable mod. It did not work for me. |
|
@cedricp This looks like the protocol description to change the CAN interface for MM-CAN access: |
|
I saw that, but I don't have the hardware to test it yet. |
|
I have one here. How can I assist you? |
|
I created an els27 branch, you can try it... (a dropdown box has beed added in the toolbar to select CAN line) |
|
First try run (without connected to car X10 ZOE) with els27 branch: |
|
This error is not related to els27 work, which ECU are you trying to connect ? |
|
Just committed a fix for this kind of problem. |
|
Ok, did a test on my car (ZOE) now but switching to "MediumSpeed CAN" does not change anything. Switched to "MediumSpeed CAN" after startup, selected my vehicle from list and pressed scan. |
|
Did you rewire the MS-CAN lines on the OBD connector ? AFAIK, it's not connected to the good pins. |
|
Just fixed an issue with MS-CAN scan, sorry, can you retry ? |
|
Yes of course it's rewired. |
|
Sorry, still only ECUs from HS-CAN. And many in MFD ECU screen. |
|
There are some more command descriptions in https://www.scantool.net/scantool/downloads/234/stn1100-frpm-preliminary.pdf which are removed from later versions of the documentation. |
|
That's weird, can you send me your elm log over ? |
|
You can also try to add a line at the end : |
|
No problem. Sent you the log by mail. |
|
Thanks,
Have you dowloaded the els27 branch and selected ELS27 dongle at startup ?

But there is no STP command inside at all :-(

Mmmmh. I downloaded the changed files only. Maybe I've forgotten something... |
|
Dry-run els27.zip without car connected still does show any STP commands in log. |
|
That is really strange... I checked the code several times... |
|
Ok, just found and fixed the problem... You can retry if you have time |
|
minor issue: elm benchmark don´t work with this branch. |
|
Can you explain ? |
|
Test elm fails remember, minor issue. els27 don´t need elm check because it works.
|
|
And by the way the serial port speed selection dropdown for ELS27 is useless. ddt4all does only auto detection. But the autodetection should run bitrates 2000000, 1000000, 500000, 115200, 38400. The ELM test seems to try a wrong port etc. Same result for me. |
|
Ok, I see |
|
yes, port selection could get some improvements: -option to remember expert mode and check recommendations. You could add a big scary message first time and a "don´t show again" checkbox. |
Ok Not sure it's a good idea, I already had bad surprises when working on the first version when expert mode was not yet in place... |
|
Here is some log extract from ELS27 session tests to MFD on ZOEs MM-CAN. You can see that some commands do not get an answer. Maybe the specific AT commands needs to be sent AFTER MS-CAN preset call? |
|
There is communication between the OBD tool and the ECU
|
|
Yes it is but the result in screen is incomplete (no data). You can also find some "no data" entrys in the log above. |
|
Have you tried to connect to another ECU on CAN line 2 ? Maybe a firmware issue on the ELS side |
|
Yes, its the same (bad) result with other known ECUs like Radio. |
|
Now els27 branch is master? |
|
Tested with my dacia Dokker and mod els27. Canbus ecus works ok. Medianav ECU dont detect using scan. We need to know how forscan works. |
|
Tested again with last version. Canbus 2 @500k works ok changing options into dacia medianav, but... when i select canbus 2 @500k and push scan ecus, no ecus found. After scan medianav shows NO DATA all options. Need to change canbus 2 500k to other option, change again to canbus 2 500k and push refresh. |
|
Ok, I think I found why, update and retry, that should work now |
|
log from session attached. can 1 scan (no ecus ok, testing on table) Can 2 500k scan, no ecu found, but changing options works after that. Tested changing boot logo from renault to dacia. |
|
It is on usb_can branch only 4e9eccc |
|
yes, tested with this version. |
|
ok, i test with my old "switch" cable. With els27 medianav VIN shows NO DATA, but with elm327 switch shows ok. elm327 els27 els27 can timeout 1000. one option start to work. |
|
log (last test) |
|
as this is current, and people are having trouble connecting if your trying to communicate with radio/NAV units, the CAN for them is indeed, hope this helps peoples :) |

Obdlink SX mod to obtain can2. We can adapt 6-13 and 12-14, but need software support "RTS relay" used in forscan. We need to know how it works to add into ddt4all. |
|
This should be very easy as it just uses the serial RTS (virtual) output pin to switch the CAN lines. |
|
Easy to do mod, but needs changes at software side. I don´t know if chinese ELS27 has integrated rts relay switch or different system. |
Hi, Can you activate power folding mirror on DCM ? I am trying to do this but I couldn't. Please guide me if you been success. Thanks |

Hi to all,
I've seen in last version of ddt4all the new icon of ELS27. After a quick reserch of information I know that this interface is better than ELM (faster, stable and use Mcan and Lcan at the same time) but....we need to modify some wiring for use it with a Megane 4? It seems this interface born for Ford and Mazda cars, not for Renault. On a russian website there is a modification of the els27 but no one have had success with the connection. Do you have more info? What kind of chip we must have insiede?
Thanks
