Some pins can legitimately be covered by tests on other pins : failure of a clock pin can be detected through absence of data for example (provided you can distinguish between absent data and 0 (or 1) data, e.g. by reading a signature) but you must prove coverage. This will all be in the FMEA : if you find holes in the FMEA, shout about it. | |
| Jan 14, 2022 at 14:04 | comment | added | jani | dFMEA was done for this system. I wasn't involved. I could review it. I'll try to find out how radar and camera interface with devices (e.g. ASIC) or what radar and camera pins are connected to devices internal to ECU. Since external to radar is antennas and external to camera is waves, there should be no pins externally? I understood these faults should be addressed during FMEA but generally speaking what internal radar and camera pins need fault detection? | |

Just because it is giving you a video signal doesn’t necessary mean the camera is fully operational. One would expect if you are working in this industry that you do FMEA to work through these questions. | |
| Jan 14, 2022 at 9:01 | comment | added | jani | In my current project, the ECU's are Radar and Camera. Since radar's external interface is antennas, there are not external pins for detecting faults? Since camera's external interface is wave signal, there are no external pins for detecting faults? I'll try to find out radar and camera internal interface pins. But generally speaking, consider a non-standard camera interface that has video pins, a pin for synchronizing camera with some device like FPGA, and some control pins. Is it necessary to detect faults on these camera interface pins? If yes, why? | |

I did the implementation but I didn't know why fault detection was required for some pin but not others. | |
