I have a service bullintin from fisker where you use a can analyser to run a special script to reset soh in id194 in bms
please tell me if it can be done with normal fisker tester and how??
Kind regards Michael
The tool from Fisker only was able to change the SOH from zero back to what the EBCM had stored the same goes for Prodis if you use Prodis you need to use the EBCM files but it only was designed to reset from zero . You won’t be able to reset to 100% because the battery is no longer at 100% . I doubt after 8 years the original EBCM was showing 100% .
