Conclusion of the programming event (Software reset, to be synchronized with optionally running utility files in
parallel):
ReturntoNormalMode request ($20).
•
Use service $20 to conclude the programming event. This will force the ECUs to perform a software reset
and transitions the LS-CAN subnet from high speed mode to normal speed mode.
