VVDI damages TC275 for some reason.

Use CG100X, works perfect

I managed to read and write the module with Multiprog.
After clearing the crash, now I have the following faults permanently stored:
21F4DA – High-Voltage Battery Unit, SME,“Estimation of stationary period: estimation failed due to implausible values”
21F306 – High-Voltage Battery Unit, Control Unit “Idle time estimation: estimation failed”
21F21F – High-Voltage Battery Unit, Main Switch Contactors “Measurable maximum number of shifting exceeded”

I have no readout of the faults before the crash cleanup and I'm not sure whether the faults were existing before that, but the car has low mileage so I do not expect exhausted contactor for example.
How those faults can be cleared?

Regards,

Has anyone else encountered this problem? I have the same problem with Virgin. I've done several cars so far and haven't had any problems. The current ilevel on this car is 25-07-538.
maybe someone knows how to solve this

have you solved this? i had this issue and my problem was at the front fuse inside the battery, was not replaced and suspected that this issue screwed my sme....

Yes.
The car didn't have those errors the next day after going into sleep mode.
Always replace the front fuse. It operates in reverse: whenis good, it is open-circuit.
Usually, the connector is even unplugged after opening the battery pack following the triggering of that fuse.
