During power-up initiated BIT, chip cautions should not appear. If one or more chip detectors fail, which BIT caution will appear?

• A. CHIP IBIT FAIL
• B. CHIP DETECT FAIL
• C. CHIP FAIL
• D. CHIP OK

Answer: (C)

Power-up initiated BIT runs at startup to verify the health of each chip and its detectors. If everything passes, no chip cautions appear. When one or more chip detectors fail, the system flags a general CHIP FAIL to indicate a fault within the chip’s functionality, since any detector failure compromises the chip’s reliability. The other options don’t fit this scenario: CHIP OK would mean all clear, CHIP IBIT FAIL is associated with an in-flight or ongoing internal test rather than the power-up BIT, and CHIP DETECT FAIL would imply a different, more specific detector condition than the overall chip failure reported during PBIT.
