The ECO controller processes signals from the vibration select switch and the throttle switch to control the
discharge rate and direction of the vibrator pump. The ECO controller monitors the state of the motor rotation
sensors (front and rear) that are connected to the T/C controller via CAN, in order to control the torque in
accordance with the road surface condition. (Anti-spin control)
The ECO controller has safeguard features (error detection, error display and error bypass action) and displays
each status with LED indicators.

Abnormal : An error code depending on the error type is indicated by a combination of long and short red LED
blinks. (Error code can be viewed when using service tool) If more than one error occur at the same
