Permanent faults on LIN networks: On-line test generation

Permanent faults (e.g., due to electronic components aging) represent a real problem in nowadays digital systems working in automotive vehicles. Mandatory tests should be done at the vehicle key-on in order to detect damaged elements. Generation and validation of these tests can be improved in a great manner considering the characteristics of the target distributed subsystems. In this work, an approach for in-field detection of permanent faults in a LIN network is proposed.
