Iveco Daily Euro 4. Manual — part 266
Drive side air bag module
For removing air bag module, the following is needed:
- observing safety rules;
- disconnecting battery cables (first negative cable, then
positive cable) and isolating them by applying an adhesive
tape on pins;
- waiting for at least ten minutes before resuming
operations;
- unscrewing the screws located at steering wheel rear
side, and, in order to be able to gain access to each screw,
rotating the steering wheel in such a way that you can
always operate from steering column upper half-shell
side;
- lifting the module by just what needed to be able to
disconnect the connector that is placed at the centre of
the module;
- removing the module from steering wheel.
Where passenger side cushion is not present as
it is optional, on relating connector there is since
vehicle
production
mounted
a
specific
resistance for simulating the charge (R = 2.15
Ohm + 0.35).
NOTE
Passenger side air bag module
For removing air bag module, the following is needed:
- observing safety rules;
- disconnecting battery cables (first negative cable, then
positive cable) and isolating them by applying an adhesive
tape on pins;
- waiting for at least ten minutes before resuming
operations;
- unscrewing the screws fastening instrument panel upper
coating (including the screws that are present near
central air diffusers);
- removing the coating;
- disconnecting module cable connector from air bag
cable;
- unscrewing the four screws, two per side, which fasten
module support bracket to body and removing the
module.
!
Not activated air bag modules, after they have
been removed, must be put back into a special
locked cabinet with the plate resting on the plane.

Spiral contact
For removing the spiral contact, the following is needed:
- removing the drive side air bag module;
- aligning the wheels and keeping them in such position
throughout the operation;
- unscrewing the nut which fixes the steering wheel to
steering column;
- always with the vehicle having the wheels aligned,
marking the position between steering wheel hub and
steering column;
- taking out the steering wheel paying attention not to
unthread spiral contact cable;
Where steering column switch unit is replaced,
it must be replaced by a steering column switch
unit comprehensive of spiral device.
NOTE
For remounting the spiral device, the following is needed:
- making sure that wheels are aligned;
- if spiral device has not to be replaced, after taking off
either adhesive tape or the clamp previously mounted,
remounting the spiral device without rotating the upper
cap, then screwing the three fastening screws;
- where a new spiral device is mounted, after fixing it to
steering column switch unit, tearing off plastic tab locking
the upper cap and checking that the upper cap is not
rotating;
- connecting air bag cable connector to spiral device cable
and fixing spiral device cable to steering column through
suitable clamp;
- mounting the two half-shells of steering column fixing
them to their support plate through special screws;
- cautiously entering the cable, to be connected to drive
side air bag module, into special slit on steering wheel
hub;
- mounting the steering wheel making previously marked
references match;
- tightening the nut, fixing the steering wheel, at prescribed
torque.
!
Make sure that steering wheel removal has
caused spiral device upper cap lifting. Where
upper cap rotates, it has to be locked by taking it
outwards; if a click is heard, it will mean that the
locking has occurred.
- removing steering column lower half-shell by unscrewing
the three fastening screws;
- operating from inside, removing steering column upper
half-shell by unscrewing the two fastening screws;
- cutting the clamp fixing spiral device cable to steering
column and disconnect spiral device cable connector
from air bag cable;
- unscrewing the three screws fastening spiral device to
steering column switch unit and removing it.
!
Spiral device must be removed without rotating
the upper cap, locking spiral device position by
either a clamp or some adhesive tape.

Immobilizer present on Daily E4 differs from previous one in some features:
- “Immobilizer” central unit is not present any more, but this function has been integrated inside Body Computer;
- the warning lamp has a different symbol;
- a display screen is present where messages relating to the system are displayed (COMFORT).
Signal received from the “transponder” from the key is sent to connector AV to pins 8 and 7. Body Computer communicates
with central unit EDC 16 through “C” Can line and, if the signal is acknowledged, start-up enabling is sent to central unit EDC.
By rotating start-up key, engine lock is only de-activated if protection system acknowledges the code that was transmitted by
the key.
Body Computer through “B” second Can line communicates with instrument cluster, where Immobilizer warning lamp is present
(change of symbol with respect to previous version).
- warning lamp on: key not acknowledged;
- warning lamp off: key acknowledged.
A warning lamp on after approximately two seconds from vehicle start-up not necessarily means system failure but can mean
a particularly low charge status in battery.
Where such event occurs, in order to make a system test, vehicle must be stopped and engine put off. Rotate the key again:
warning lamp will go on and shall go off after approximately 1 second.
Where warning lamp remains on after this test too, repeat the operation keeping engine stopped up for more than 30 seconds.
if the problem persists, comply with provided prescriptions appearing on display screen (if any).
Emergency procedure
It is necessary to enter “PIN code” only operating on accelerator pedal as described below:
- Insert the key to ride position.
- EDC warning lamp, after ~ 2 seconds, starts flashing rapidly.
- Press accelerator pedal and keep it pressed for ~ 15 seconds.
- EDC warning lamp starts flashing slowly.
- When the number of flashings is matching “PIN code” first figure, fully press down accelerator pedal, then release it again.
(While this pressing operation is performed, EDC warning lamp remains off).
- Go on with reading and performing relating pressing operation on accelerator pedal for remaining four “PIN code” figures.
- At the end of the sequence, if entered code results to be correct and no failure is present in the system, EDC warning lamp
stops flashing: operation terminated correctly.
- Start up the vehicle.
Keys
- New key memorization procedure (centralized by Iveco)
- New type of key with trasponder (with or without wireless control)
- You can memorize min 1 up to max. 8 keys
