DESCRIPTION AND OPERATION

Delayed turn off relay - remains energised after
switching engine off and exiting vehicle, enables self
levelling to occur for 20 seconds. If vehicle is
stationary, the ECU will energise the relay every six
hours to allow self levelling to occur if necessary.

Reservoir pressure switch - when the ECU detects
an output from the pressure switch indicating low
pressure, the ECU will operate the compressor relay
until the pressure switch indicates normal pressure.

Diagnostic plug ground - note that the two halves of
the diagnostic plug are normally connected. When
disconnected the system will not operate. It will
remain frozen at its current height until reconnected.

Disable switch - In the disable position the switch
sends a door open signal to the ECU. This freezes the
system in position at speeds below 56 kph (35 mph).
