Hello,
 
	 
 
	Im trying to remove some fault codes from an ecu, when ecu is flashed - car starts once, shuts off and cannot start.
 
	its a checksum error.
 
	 
 
	im reading/writing with kessv3, I made DTC-off (removed error codes) with SVEDIT.
 
	 
 
	Can anyone help fix the checksum error?
 
	 
 
	thank you!
