Accelerometer
In the event of accelerometer failure:
• Inspect physical placement U6150 and their related components on main PCB
board (see accelerometer schematic page on next slide).
• Connect the board to a display and power the board/display with battery or factory
cable. Launch CQA app, test each accelerometer at a time. Look for accelerometer
G-force activity on all axis X,Y,Z. As you change the board orientation to have
positive X,Y,Z accelerometer reading. Good accelerometer IC will have G-force
reading for each positive axis closed to 9.8 else the IC is faulty.
