On the 20-way connector 61071A the D+ signal is not available.
IVECO therefore recommends use of a relay which is able to “read” the
engine speed from terminal 10 of the 12-way connector 72075A (see
example in Figure 6).
This relay must be set so that, with an engine speed of >400 revs/min, a
12 V output is activated which can be used as the D+ signal.
The speed threshold for which the signal must be present is adjustable
from 400 to 2000 revs/min and can also be used for other applications in
which an engine speed signal is required.
If the RPM output of connector 72075A / pin 10 does not sup-
ply a signal, then the ECM programming must be updated; for
this purpose, contact the IVECO Assistance Service.
Connection:
● X: not used
● Y: Signal input connector 72075A / pin 10
● Z: not used
● C: not used
● 15: not used
● 30: positive shared connector 61071A / pin 11
● 31: negative connector 61071A / pin 17
● 87: normally open (closing) to be used as “D+ signal”
● 87a: normally closed (opening)
● Rated voltage: 9 ÷ 15 V
● Maximum switching current: 10 A
● Operating current: 10 ÷ 100 mA
● Protection: IP52

Only supported with Cruise Control option.
The resistors must be connected between pin 12 and pin 13. Different functions may be activated depending on the resistor value:
R = 2490 Ohm: CC stays active, just like the PTO modes (important for vehicles without Cruise Control)
R = 649 Ohm SET+:
the speed increases by +50 revs/min pulse (only when the vehicle is stationary) or adjustment of the CC speed (only at V > 30
km/h)
R = 261 Ohm SET-:
the speed decreases by -50 revs/min pulse (only when the vehicle is stationary) or adjustment of the CC speed (only at V > 30
km/h)
R = 133 Ohm RES: activation of ISC MEMO speed or resumption of the memorized CC speed
