iPhone 14 Pro Max — sensor array 0x100000: Power button flex

High confidenceVerified sourceSMC: silent sensor

On the iPhone 14 Pro Max, 0x100000 means: Power button flex.

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, the power button flex sensor has stopped responding. 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?

Inspect the power button flex (pry marks near the connector, tears), test with a known-good flex, then diode mode on the connector.
