Question:

What does the Error Code 8E or 8C, 8CA/B mean and how should it be addressed?

Answer:

The Error Code 8E or 8C, 8CA/B indicates a MEMS Sensor Error (8CA1/2/3/4, 8CB1/2/3/4). This means that there is an abnormal output from the sensor, either over 4.5V or under 0.5V. To address this issue, replace the PCB main if there is no external MEMS.

Terms:

MEMS Sensor Error: A problem with the Microelectromechanical Systems (MEMS) sensor, which detects changes in pressure, acceleration, temperature, or other factors.

Abnormal Output: When the sensor's reading is outside its expected range (over 4.5V or under 0.5V), potentially affecting the device's performance.

Replace the PCB Main: Remove the faulty PCB main (printed circuit board) and install a new one without an external MEMS sensor.
