iPhone 14 Pro Max — sensor array 0x180000: Front sensors flex + power button flex

Low confidenceVerified sourceSMC: silent sensor

On the iPhone 14 Pro Max, 0x180000 means: Front sensors flex + 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, two sensors are missing: proximity (0x80000) and power button (0x100000). 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/test the front sensors flex and the power button flex.
