An internal hardware error was detected within the module. This can be caused by external electrical noise interfering with internal components or an actual failure of the module's hardware, compromising its functionality.
Click steps to track your progress.
Implement comprehensive measures to reduce electrical noise, such as improving grounding, shielding sensitive cables, and using surge protectors.
If the error reoccurs consistently even after effective noise reduction measures, the module is likely faulty and should be scheduled for replacement.
