ESP SYSTEM Derating
▶ The Derating of the ESP system is only possible for certain vehicle categories: for their
identification and relative dispositions, refer to Attachment XI of Directive 2007/46/EC
- latest version amended. The Derating of the ESP system involves the complete
deactivation of vehicle stability control.
If derating is implemented, functions nonetheless remain active:
● ABS (Antilock Braking System) to avoid wheel locking
● EBD (Electronic Brake Force Distribution) to distribute the braking force between front and rear axles
● MSR (Motor Schleppmomenten Regelung) to control the braking effect of the engine when released
● LAC (Load Adaptive Control) to adapt the extent of braking to the distribution of the load on the vehicle
● HHC (Hill Holder Control) to facilitate breakaway from a standstill in ascent
Variation of P.T.T.
Variations of vehicle P.T.T. must be authorised by IVECO and only in certain special cases is tins compatible with the presence of
the ESP system.
In the event of compatibility, system management software must be reprogrammed; in all other cases, Derating is compulsory,
except as indicated in Attachment XI of Directive 2007/46/EC.
Wheelbase variation
As stated in Chapter 2.4 ( ➠ Page 12), the variation of the wheelbase is only permitted upon specific approval of IVECO. In the
event of approval the following alternatives may be verified:
a) To values included in the product grid
If the conversion involves a wheelbase value among those in production for the specific vehicle model, ESP system software has to
be reprogrammed.
a) To values not included in the product grid
If the conversion involves a wheelbase value NOT corresponding to any of those in production for the specific vehicle model, De-
rating of the ESP system is compulsory, except as indicated in Attachment XI of Directive 2007/46/EC.
Modification or replacement of suspensions
If an ESP system is present:
● modifications are not allowed of any suspension element;
● total replacement of the suspension is permitted with another suspension already type approved for the specific vehicle
model;
Such intervention may only be performed after obtain authorisation from IVECO and require the reprogramming of ESP system
software.
