Designed for modern Bosch EDC17 and MED17 TriCore ECUs.
An ECU checksum is a cryptographic or mathematical value calculated from a specific block of data within the flash memory. It acts as a digital safety seal. When an ECU boots up, it runs a self-diagnostic routine: It calculates the checksum of its current memory segments.
: This occurs in highly complex modern ECUs where changing one map requires a parallel calculation in a completely different area of the flash memory. Ensure your WinOLS version is updated to the latest minor revision, as EVC constantly patches these sub-routines. Conclusion
