That fault may be fatal -- as in "replace the 48V battery".

Suggest you run a Measuring Value map from that module and post it here. That should hopefully reveal something about the condition of the cells.

-Uwe-

PS: That's one of the downsides of Li-ion batteries. If the cell voltages are allowed to get too low, the BMS won't allow them to be re-charged because doing so is dangerous. At low enough voltages, lithium comes out of solution in the electrolyte and starts plating onto stuff, risking internal shorts in the cells, and then attempting to recharge them can:

Huh? Are you trying to use Measuring Blocks? This is a UDS module. It uses Advanced Measuring Values.
https://forums.ross-tech.com/index.php?threads/1905/

However, what I'd like to see is a map of all the values in that module. That's obtained using the [Controller Channel Map] function in the [Applications] screen.

here is the map for the battery. the battery V shows 42v, i do not think it is that bad, is it?

battery V shows 42v, i do not think it is that bad, is it?
You can't really assess it on the battery voltage per se. The battery consists of a number (in this case 13) cells in series. If any one of those cells is below a critical voltage (typically around 2.5V), then that's a major problem. The good news here is that this isn't the case. All the cells are still at reasonable voltages, the lowest being 3.15V.

Does the engine start and run? If so, drive it for a bit and let's see what happens to the battery and cell voltages.

And this is what I noticed. The Starter-Generator is Red marked but I can’t gain access for diagnosis. The connector and all the fuses were tested ok, the Alternator was replaced new from the dealer.

What do you mean? It shows in your Auto-Scan and it states, "No fault code found."


Code:

If starter generator is new it needs to be adapted to the vehicle. Also the way that system is setup the 12v battery needs to be fully charged before the start alternator starts charging 48v battery. However since the HV battery was discharged chances are 48v system is disabled you need to latch 48v contactor in order for 48v battery to take a charge. I believe this is part of battery monitoring module 2. Not sure if VCDS will do it. I use ODIS to latch the contactor then try charging the battery. If hv battery doesnt take a charge you need a 4,000$ battery.

Strange, now it communicates but kicks me out the module. If I am fast, I can manage to read the codes from the CC, internal check sum errors if I am not mistaken. Sometimes I can gain access sometimes no and if I access the module it kicks me out and give NO COMM to the module

Do you know the procedure ?

I have never tried with VCDS normally with ODIS only. Not sure if VCDS can close contactor but I would assume so, just haven't had time to test.

The VCDS closes the contactor.

And I also have the ODIS, and both new/DOIp and the regular VCI. Clone of corse

So I managed to the get the Alternator coded. No more codes there but BMS codes are not clearing. Contactor is closed, battery charger hooked up and still the alternator isn’t charging

If contactor is closed chances are you need a $4,000 48v battery. Common issue. Most likely scenario alternator is charging however 48v battery will not take a charge due to logic board failure.

Thank you for the info, but the battery is 42V and the full charge is 48V

Logic board failure is a different issue to battery voltage. If the logic board has failed then whatever the battery voltage it won't charge.

From what I've seen battery voltage is irrelevant as the fail safes built in will automatically disconnect the 48v battery once the battery is at roughly 10% to prevent damage to battery that will most likely diminish its capacity. You can have 42v and still have a bad battery. When logic board fails in these batteries it simply will not take a charge. I have a battery disassembled right now with logic board removed. Still shows 44v however will not take a charge. The vehicle is gone and repair after changing generator and 48v battery.
