ECS Gen. 1
Level control
- switch off
In certain cases it may be necessary to switch off the
automatic height/levelling function - e.g. when using outrigger
stabiliser legs, or a snowplough.
Switch off is activated by applying a positive signal to ECU pin
(39)
The signal can be from a switch (A), or from a relay - either of
which is fitted by the body-builder. The body-builder also fits
some type of signal to indicate when level control is switched
off.
The switch connection to the ECS ECU is as shown in the
above diagram.
When switch (A) is closed:
- if the parking brake is applied, level control is switched off on
both front and rear axles.
- if the parking brake is released, level control is switched off
on the front axle only.
Note : For level control switch off to operate, parameter ʻLTʼ in
the ECS ECU must be activated using VCADSPro.
