I looked at BCCM, BECM and TCU. All of them give a lot more live data values.

 

[dernotte]

I have upgraded the firmware but not tested it yet, Live data on TCU would be a new thing because there were not live data before.

 

[Ayepace]

There are a few new functions too. The TCU has a network connection test, a function to reset the internal battery knowledge when that gets replaced, and one for resetting (rebooting?) the TCU for example.

TCU live data includes latitude and longitude, how many satellites are seen, signal strengths, etc. I didn't see the internal battery charge % like WattCat and your old displays had, unless I overlooked it in my quick run through.

 

[dernotte]

You're right, they have included a lot of new data, including the TCU. I think I saw the TCU battery on it. I generated a PDF from the live data, I need to upload it in the cloud and download it on my computer to analyze it. They have also added the value of the software , config, ... version number on different module.

I just did a comparison on the BECM module. Before this upgrade, the report included 90 live data, now you can see 200. I don't know if the "BZ" version exposes more data, or simply because the Autel is able to decode more. We can also see everything related to the H441 update. It even exposes firmware version number. Here is a sample of data collected in Jan and in May (before and after upgrade).

This Autel update shows a lot more data for other modules too. The GWM shows 12V battery information, for example. BCCM shows a lot more charging information too. It is quite an update.

Comparing @dernotte BECM BZ report to my BV report, BZ has two additional items. #200 Calculated energy storage system energy and #156 Hybrid/EV battery charging limit.

All firmware, assembly numbers and software part numbers agree with the exception of ECU Software #3 Part number (ends with BV and BZ as expected) and Vehicle manufacturer ECU software number. Mine ends with DB and his with DE.

Nice to see the improvement on SOH on the new pack!

Although I've not done or said much lately, I'm still using the carscanner data I set up before - can I look forward to some more DID/PID's getting interpreted now by you geniuses !!! ?

 

[dernotte]

Sure

Got my hands on a second hand maxiCOM MK900BT with Jaguar V1.70.
I currently have the 72% charge limit with a Traction Battery warning on the dash.

Should I have been able to identify which cell or group of cells are faulty?
I took this report: MY19

Individual module voltage
Module ID Module voltage Within/out of tolerance
1 10.80V Within tolerance
2 10.80V Within tolerance
3 10.80V Within tolerance
4 10.80V Within tolerance
5 10.80V Within tolerance

All 36 identical.
Should any bad ones have shown here, or do I need to look at some of the Live data?

I have a warranty appointment to fix this soon, but my car is 8 years next year so this scanner will get handy either way.

 

[dernotte]

I don't have the Autel device in front of me, but if you look at BECS module , you should see a section for maintenance routine, different from live data. In that section, you can run a routine to get individual SOH.

Thanks.
They were all within tolerance ... (the individual SOHs. Did not do the overall SOH that required a 20min drive ...)
How did you manage to generate a PDF report of the Live data?
In that menu, I don't see the Save icon .. (could it be because I did a Standalone diagnostics perhaps?)

I noticed scrolling through my live data that one module failed the MAVD check. (Moving Average Voltage Deviation).
This could perhaps be the reason for the dash Warning triggering?

A tip for others entering the BECM Live data menu of the MK900BT and are getting the connection dropped message:
I found that as soon as the Hex data listings are showing, quickly scroll down to single line objects only, and the connection stays.
Good to go after that.

Is your device up-to-date?

Saving and printing are icons along the top of the display.

Yes, no updates available. Active subscription from previous owner..
When entering the live data menu the top line dissappears. I have seen this on all YouTube videos as well.. Strange.

I can’t print directly from the Autel because I don’t have any compatible printer so I have to create a PDF, save it in the acrobat cloud, download it from acrobat cloud on my computer and print it from there

File transfer in Team Viewer works fine too. ☺

"How did you manage to generate a PDF report of the Live data?

Figured it out after reading the manual.
In the Live data menu, the swipe down tab icon at the top of the screen in the middle has to be tapped, not swiped, and viola, the missing toolbar re-appeared.

In Remote Desktop Team Viewer file transfer, PDFs are found here: /storage/emulated/0/Scan/Data/PDF/
