VolvoECS vacant fault SR
Publisher:acer Release:2007-9-7 Hit:5689

ECS system is what we normally electronically controlled suspension system, it is in the vehicle load changes stochastic control and adjust the chassis height, compared to the previous signal of a more rapid. At the same time it can also drive through the panels on the chassis control button direct control movements. The drive control panels on the switch to raise the passing through its members can send signals to the control unit. Before and after the control unit through the solenoid valve to send a corresponding signal to the airbag inflated or gas. At the same time fixed in the base after the height sensor under load change to the control unit can also send signals, similar changes in the chassis height. ) JAsm>
        ECS system fault diagnosis, through the transfer of the fault code, can also airbag indicator of the state of SR subcontractors. The lights are usually four situation, methomyl, flash, flash, and on and slow. Normal eliminate that system, stop working. Two second flash, flash for that system work. If the balloon not normal movements, it may be due to mechanical failure solenoid valve cards death. The second blinking, blinking slowly, but that the normal work of the low air pressure. Probably the main low pressure cylinders, pressure relief valve failure or sensor failures. But if the airbag can slow blinking rapidly rising, while pressure sensor failure can be shorted their plugs to further confirmation. Chang Liang said Fault system. Inspection system can supply high sensing, and the solenoid valve and control unit in the signal transmission. In addition, the normal speed signals. Speed Signal impact airbags up speed, is to ensure traffic safety. The fault signal can even lead to the control unit outages. 8FQo (
        Common Faults of the following: 1. Airbag not normal landing or instability. Possible causes internal solenoid valve failures, such as a short circuit within the valve or milk intake valves can lead to internal functioning. 2. Electromagnetic valve frequent irregular movements. Possible reasons for a high degree of internal friction sensor or signal of the intake resulting potential bias or poor. In addition, the suspension system can result in significant leakage magnetic valve embankment frequent moves. 3. Traffic in the unprovoked balloon will rise. Possible reasons, odometer or speed sensor failure, thus the wrong signal to the control unit, or because the signal to the control unit circuit interruption. Tcbc +
         Additionally, the most common leak mainly in the following three conditions: balloon leak itself, solenoid valve leakage and leakage flu contained. Flu contained valve option for the project, its role is to detect a vehicle load driving wheel brake pressure regulation. Its signal from the pressure balloon. Their conditions are available on the leak detection 3-2-8 spraying, the latter two to unplug silencers, direct spraying in the exhaust port, otherwise difficult to observe. E
