The ECS is the abbreviation for "Electronic Control Suspension". This ECS system automatically controls the height of a vehicle level and the damping force of shock absorbers according to road condition. So it improves riding comfort and steering stability. For controlling a vehicle level and a damping force of vehicle damper, the ECS system needs various different signals from many sensors or other control modules. These signals are delivered to the ECS ECU through CAN communication line.
The ECS ECU checks CAN communication circuit for a normal operation and if the messages from cluster do not receive for a certain time, this DTC is set.
