EFUSE-W141
EFUSE_w141_epas1SelfTestFail
Was bedeutet EFUSE-W141?
Tesla Warnung-Code im Elektronische Sicherung-Modul (EFUSE). The power steering can only be disabled due to the presence of "E-fuse self-tests" upon vehicle wake-up. If either the Electric Power Assist Steering (EPAS) primary or EPAS secondary fault at wake-up, there will be no assistance from the start. Sleeping and waking the vehicle will force a re-test, which will pass the next time if the conditions that caused the initial failure are not present. If the failure occurred during the drive itself, it is less likely to be E-fuse related. Once driving is underway with a working EPAS, the E-fuse software state is locked out for safety reasons and only the hardware sensing can make it trip. Both the EPAS circuits would have needed to trip their E-fuse during the journey for this to be the case.?
