Electronic Control Suspension
C1514 Valve Switch-ON Time Exceeded - 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 the components of the ECS system, the compressor is installed near the front-right tire. This compressor's function is to charge the air into each air-spring or the reserver tank by the ECS ECU's order. Also, the solenoid valve assay is set up next to the compressor and consists of five solenoid valves. These valves' function is to distribute the air to each air-spring and the outside.

DTC Description

In a case that the compressor or solenoid valve assay is excessively operated, the ECS ECU expresses it as a DTC, that is, the ECU shows C1514 on the scantool. When the compressor doesn't work during a certain time, the DTC is erased.

DTC Detecting Condition





* In a case of this DTC, C1514, if the leveling control is inhibited for a certain time below, this problem would solve. Next, go to "Verification of vehicle repair" procedure for verifying that the problem is completely solved
1) Causing by solenoid valve: At least for more than 7 minutes, do not work the leveling control.
2) Causing by reverse valve: At least for more than 5 minutes, do not work the leveling control.
