Abstract (en)

[origin: WO2006063919A2] Modern methods for the modification of software status in engine control devices no longer guarantee direct recognition of a modification in software status for control device software. According to the invention, a check sum (308) and an initial value (310) are introduced into an original software status of control device software at a predefined point. Control device software (312) that has possibly been modified in relation to the original software (302) is loaded into the engine control device. Check sum verification of the currently loaded control device software (312) is carried out after the start of the engine control device. The calculated check sum of the currently loaded control device software (312) is compared to the check sum (308) which was introduced into the original software status (302). If both check sums are not identical, the currently loaded control device software (312) is not modified, and a label (318) is read out, said label being described by tool software upon modification of the control device software (312). The label contains information on the type and scope of a modification thus established.
