Sensor error.
Please contact your dealer or Pioneer Service
Center.
This message appears when an abnormality of the
installing direction is detected or an abnormality is
detected from any of the built-in sensor (GYRO
sensor, G sensor, temperature sensor or ADC).
Check the installation angle and direction,
then reset 3D Learning status.
Check External Connection Test in Test mode.
If the sensor check is NG, replace
CHIPS B COMP Unit.
