Electronic Control Suspension
C1284 Acceleration Sensor Voltage Failure - General Information

Component Location





General Description

The ECS is the acronym 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. Among components of the ECS system, a acceleration sensor is set up to detect the acceleration of a vehicle body. For more detailed measurement, three acceleration sensors are installed on the vehicle. The acceleration signals from these sensors are sent to ECS ECU. And ECS ECU controls the damping force of the vehicle dampers with other sensors' signals.

DTC Description

The ECS ECU monitors the state of power supply to acceleration sensors and if it is out of normal range, this DTC is set.
