H200 GPU Fallen Off Bus
NVIDIA driver logged XID 79 indicating the GPU has fallen off the PCIe/NVLink bus. This is triggered when an uncorrectable double-bit ECC memory error (DBE) or link-layer parity collapse isolates the HBM3e subsystem, causing the ASIC microcontroller to halt execution and sever host MMIO communication.
Contact Sensor Impedance Fault
The quad red LED blinking fault indicates that the skin-contact bio-impedance sensing circuit has detected an out-of-range impedance value (>2.5 MĪ© or shorted <50 Ī©) across the four bipolar treatment head electrodes, triggering the MCU auto-cutoff safety interlock.
EEV Stepper Motor Fault
Error 07 indicates that the refrigeration circuit controller detected a synchronization loss, open/short circuit, or mechanical seizure in the electronic expansion valve (EEV) stepper actuator during positioning cycles, locking out compressor operation to prevent liquid floodback.
Roll Axis Motor Stall
Error 03 triggers when the gimbal's motor controller detects an overcurrent condition on the roll axis brushless DC motor drive phase, caused by physical obstruction, severe center-of-gravity clamp misalignment, or hall sensor feedback divergence.
Locked Motor Rotor Position Error
The LE error indicates a Locked Motor condition where the Main Control Board detects that the direct drive motor cannot turn or fails to receive rotor positional feedback pulses from the Hall sensor (RPS) during operation.
APU Thermal Trip WHEA 18
WHEA Event 18 designates an uncorrectable Machine Check Exception (MCE) generated by the AMD Ryzen Z1 Extreme APU internal hardware monitors. The APU initiates an emergency thermal cut-off (PROCHOT_EXT / THERMTRIP#) when localized silicon junction temperatures exceed the 100Ā°C T_junction limit or severe transient voltage instability occurs under Turbo (30W+) profiles due to cooler mounting pressure loss or phase-change thermal pad displacement.
VibraRise Mop Mechanism Jammed
Error 44 triggers when the motor driver detects persistent overcurrent (stall condition exceeding threshold current >1.2A for 2+ seconds) or Hall-effect position sensor timeout while attempting to actuate the VibraRise 3.0 mop lifting carriage.
HV Isolation Degradation Warning
BMS_b017 indicates that the Battery Management System has detected a loss of electrical isolation resistance between the 400V/800V high-voltage bus and chassis ground, falling below the critical threshold (typically <500 Ohms/Volt or <100 kĪ© total resistance).
LDS Turret Blocked Error 1
Error 1 indicates that the Light Detection and Ranging (LDS) sensor module cannot rotate freely or optical return signals are obstructed. The mainboard optical encoder detects low/zero RPM or stalls, triggering motor drive cut-off protection to prevent driver burnout.
Gimbal Roll Overload & IMU Desync
Error 16002 triggers when the gimbal control unit (GCU) detects excessive current draw on the 3-phase brushless roll motor driver alongside a divergent angular velocity reading between the gimbal internal 6-DOF IMU and the flight controller IMU.
