And with some aircraft you can still do that. For instance, with the AW139 you can activate the MGB fuzz burner three times in one flight. If the chip light clears the MGB is considered good. If after the third attempt to clear it the light is still on or the light clears but comes back, then action needs to be taken.
Perhaps the 175 has something similar but the light stayed on after the maximum number of fuzz burner attempts were made???
