iPhone 14 Pro Max — sensor array 0x1c0000: Charging port + power button + front sensors

What does this code mean?

SMC “BSC failure” panic: the system management controller (built into the SoC) periodically waits for a response from each mandatory sensor; here, three sensors are missing: charging port, power button and proximity. With no response, it forces a restart, which repeats roughly every 3 minutes (≈180 s) as long as the sensor stays silent.

Which part to test first?

Check all three flexes; a simultaneous failure points to corrosion or a common logic board problem.
