Repositioning electronic control units
IVECO recommends avoiding modifications which entail the repositioning of the electronic control units. However, if repositioning
is unavoidable, please follow the instructions below:
● the electronic control units must be positioned on the chassis or in the cab and secured with a fastening similar to the original
one (i.e. suitable bracket);. The device must not be rotated in relation to the chassis so as to avoid potential malfunctions (eg.
infiltration of water). Therefore the original positioning must also be maintained;
● the electronic control units must not be fitted on the counter chassis;
● the covering must always be reinstalled;
● the control units must not be subjected to impact from road debris or stones coming from the vehicle's wheels when in mo-
tion.
5.4 ELECTRICAL SYSTEM: CURRENT INTERVENTIONS AND DRAWS
General information
Vehicles are set to function normally with a 12 V electrical system.
The chassis represents the grounding (it acts as a current return conductor between the components located on it and the bat-
tery power source/alternator) and it is connected to the negative pole of the battery and components, if an isolated return is not
provided for this.
When installing additional equipment or additional circuits, the following indications must be taken into account and, depending on
the complexity of the operation, there must be proper documentation (e.g. wiring diagram) to match that of the vehicle.
The use of cables and connections with colours/codes identical to those used on the original vehicle makes installation correct and
facilitates any repair work.
For effective and proper use of the electrical system, specific connection points for additional equipment have been prepared. This
was necessary to exclude any type of alteration of the basic design, so as to ensure its functional integrity and therefore maintain
the vehicle guarantee.
Note
For more detailed information on the vehicle's electrical system, please consult the NEW DAILY 4x4 Repair Manual, printout no.
603.95.979.
This manual is available at the Service Network and can also be obtained from Sales Agencies.
Precautions for work on the system
▶ Interventions on the electrical system (e.g. removal of cables, addition of circuits, replacement
of equipment or fuses etc.) carried out in a manner which is not compliant with IVECO's instruc-
tions or carried out by non qualified personnel, can cause severe damage to on-board systems
(control units, wiring, sensors etc.), affect driving safety and good operation of the vehicle and
cause serious damage to the vehicle (e.g. short circuits with the possibility of fire risk or destruc-
tion) which is not covered by warranty.
Before removing any electrical/electronic equipment, disconnect the ground cable from the battery negative pole and then the
positive cable.
To prevent damage to the vehicle's electrical system, follow the instructions of the cable manufacturer.
● The cables must have suitable sectioning for the type of load and the position of the load in the vehicle.
● The power cables (+ direct) must be:
■ individually intubated in conduits (of suitable diameter) and not together with other different cables for signal and negat-
ive;
