● The K15 Remote control must not be activated with the engine running.
● Similarly, to avoid unexpected movements of the vehicle with gear engaged, the engine must not be running when
the K15 Remote control is activated.
If, in spite of such requirements, engine operation must still be possible, IVECO recommends using the RunLock function offered by the Ex-
pansion Module (if present): refer to Chapter 7.3 (

Page 5).
5.3 ELECTRONIC CONTROL UNITS
5.3.1 Precautions
In order to avoid operations that could permanently damage or degrade the functioning of the vehicle ECUs, it is advisable to:
● remember that connection and disconnection from battery terminals may generate voltages that adversely affect vehicle elec-
tronic systems and control units;
● do not disconnect and/or connect connectors from/to the control units with engine running or control units powered;
● detach the electronic control units where particular processing operations involve temperatures above 80 °C;
● absolutely never employ a rapid battery charger for emergency start-up because it could damage the electronic systems, par-
ticularly the control units that manage the ignition and power supply functions;
● do not supply current to components served by electronic modules with jumper cables
● connect the control units equipped with metal casing to the ground of the system using a screw or bolt unless otherwise spe-
cified.
In case of any work on the chassis requiring arc welding:
● disconnect CBA1 from the battery positive terminal and do not connect it to the chassis ground;
● disconnect the control unit connector;
● disconnect the control unit from the chassis (in case of welding near the control unit itself);
● perform welding with continuous current;
● ground the welding machine as close as possible to the welding point;
● do not place the battery cables parallel to the vehicle's electric cables.
▶ When the operations have been completed, restore the original conditions of the wiring (paths,
protections, strips), making sure that the cables are not in contact with metallic surfaces which
could affect their integrity.
▶ It is prohibited to make any changes or connections to the CAN lines where any change is
strictly prohibited. Diagnostic and maintenance operations can only be carried out by authorised
personnel with IVECO approved equipment.
Note
For any exception to mounting instructions, IVECO's written authorisation is necessary.
Lack of observance of above described prescriptions involves guarantee lapse.
