Before starting to replace an ECAS1 valve, ensure you carry out the
following steps:
– Depressurise the pneumatic suspension
– Lower the lifting axle (if installed).
– Switch off the ignition.
– Deactivate the ECAS stand-by function )if available(.
4.2 Single block ECAS1 valve
4.2.1 Disassembly
Detach the device for ease of inspection. Do not disconnect
–
any cables or pneumatic lines at this stage.
– Label the pneumatic lines according to the port designations on
the housing. This step is necessary to ensure that subsequently
