I think BMS_a128_SW_shunt_MIA (shunt is missing) seems to be the main problem.

Is cable between HV controller and the the shunt connected?

 

[telk]

Maybe do you have photo or tips which one is that cable? Nobody opened battery cover under rear seat before me, I connected all which was disconnected for pyrofuse change.

Any ideas why I got pyromia fault? That is connected with pyrofuse but that part is installed new and from dealer.

Don't know anything about 3, but just a shot in the dark, maybe its a latching error and needs reset with Toolbox?..

 

[Michal Foksa]

Pyro fuse is on passenger side mounted to the shunt (on LHD vehicles). You must have touched shunt.

Wiring from Shunt to BMS are ok. Plugin to SHUNT too. It looks like BMS is faulty?

Hi guys, I ordered BMS module, used one. Should I recode it by toolbox? Is it difficult? From where could I get program?

[telk]

Yes, I waiting for new BMS. Will report when finish of installation.

 

[Issamassad]

Ok, Im just curious .. Have you clean you RCM? I didnt do it yet and i was wondering if that can be the problem ..

 

[telk]

RCM is not point with it. Yes, it is cleared and not helped. From where are you?

 

[Issamassad]

Eastern europe. What im planning to do is to check the input voltage to HVC.

 

[telk]

If you solve just give me info.

 

[Issamassad]
