4 Replacing an ECAS1 valve
4.1 Preparations
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 Disassembly
– Detach the device for ease of inspection. Do not discon-
nect any cables or pneumatic lines at this stage.
– Label the pneumatic lines according to the port designa-
tions on the housing. This step is necessary to ensure that
subsequently the pneumatic lines are correctly reconnected
to the new valve. Once you have completed this step the
pneumatic lines can be disconnected using an open-ended
spanner (size 27).
