Vehicle pipe installation
Before use, the new pipes must be thoroughly cleaned inside, for example by blowing air with a compressor.
The pipes must be fixed to the frame with elements which envelop the pipe completely and which may be metal with
rubber/plastic protection or be made of plastic material.
Provide appropriate distances between one fastening element and the other: generally, max. 500 mm for plastic pipes and max.
600 mm for metal pipes can be considered.
In order to avoid deformations and tensions at the time of closure of the couplings for the plastic pipes, it is necessary to take care
of the line and the accommodation of the fastening elements, rubbing should be avoided with the fixed parts of the vehicle and
meet the necessary safety distances from moving parts and heat sources.
▶ After each intervention, both on the system and on the equipment, it is necessary to perform a
precise air bleed operation (on vehicles with the ABS/ESP system only using special apparatus
present in the IVECO Authorized Workshops).
Note
The fluid discharged from the hydraulic circuit must not be used again. Top up using only new fluid of the prescribed type, con-
tained in original, sealed containers that should only be opened when using the fluid.
Bleed air using "E.A.SY." on vehicles with ABS//ESP system
The conventional manual bleed operation may not be sufficient on vehicles equipped with the ABS/ESP system.
Therefore the operation must be carried out which will be guided by "E.A.SY." This makes it possible to perform a full bleed
(primary circuit and secondary circuit of the modulator).
Follow the instructions as they are displayed, making sure not to exceed the pump and solenoid activation time to avoid super-
heating the components.
If this happens, the system switches off and you must wait for the preset time before resuming the operation.
▶ When replacing the modulator (supplied by IVECO Parts already filled with brake fluid in every
part), it is enough to use the manual bleed procedure, taking care however not to empty it and
not to cycle the pump and solenoid before filling is completed.
The ABS/ESP modulator devices are situated on the chassis in the engine compartment and must not be moved.
▶ Perform the necessary checks and controls after every such task at an Authorised Workshop
having specific equipment.
ESP (Electronic Stability Program)
ESP is an electronic function which contributes to the vehicle's active security and therefore the European Legislation, relating to
vehicles approved also for off-road use, provides that it is obligatory up to GVW of 3.5 t.
Through the continuous analysis of acceleration signals, yaw, steering angle and wheel revolutions (see Figure 10), an ECU com-
pares the set trajectory with that actually travelled by the vehicle.
if there is the danger of instability, the system activates the modulated braking of one or more wheels and intervenes in engine
management by reducing its speed.
