G sensor 供电电压。该电压等同于
VIO18 ，该电压异常系统就无法开起来
，所以 sensor 不良不用 check 此电位
。
G Sensor voltage is as same as
VIO18. if this voltage is in error,
system will not boot on. Therefore it
is not necessary to check this
voltage when sensors are on failure

BB-6 sensor function fail ( 感測器不良 感測器不良 ) (1/2) ) (1/2)
•所有的 sensor 都是由 I2C 總線，中斷信號，電源組成 .I2C 總線上 sensor 間會相互影
響，所以維修某個 sensor 不良時需要同步檢查其他 sensor 路徑。
•All sensors are consisted by I2C bus, interrupt signal and power. Sensors on
I2C bus are affected by each other, therefore related sensors checking is
needed when repairing sensor.

G sensor I2C 通過上拉電阻連接到 CPU ，此 I2C 與touch panel 共
用， VDD18_PMU 異常會造成所有 sensor fail 。
G sensor I2C connect to CPU with Pull up resistor, which share
with touch panel, VDD18_PMU error will lead to all sensors
failure.
