2007 Alfa Romeo 166 relay

IMPORTANTIn the case of fast start-
ing, turning the key directly from STOP
toAV V, the recognition code might not
be transmitted completely, preventing the
engine from starting: try again more
slowly.
IMPORTANTThe system is protected
by two fuses housed in the main fusebox
(see “If a fuse or relay blows” in the
chapter “In an emergency”).
EMERGENCY STARTING
If it is not possible to deactivate the en-
gine inhibitor with the ignition key, Alfa
Romeo Authorized Services can carry out
the emergency procedures using the code
of the CODE card, or, you may do this
yourself, following the procedure de-
scribed below.
IMPORTANTYou are advised to care-
fully read the entire procedure before car-
rying it out.If a mistake is made during the emer-
gency procedure, the ignition key should
be turned to the STOPposition and the
operations must be repeated from the s-
tart (point 1).
1) Read the 5-figure electronic code on
the CODE card.
2) Turn the ignition key to the MAR
position.
3) Fully depress the accelerator pedal
and keep it pressed. The EOBD/fuel sup-
ply-ignition system failure warning light
will come on for eight seconds ap-
proximately and will then go out; now re-
lease the accelerator pedal.
4) The warning light begins to
flash: after it has flashed for the same
number of times as the first digit on the
code of the card, press completely and
hold down the accelerator pedal until the
warning light comes on (for 4 sec-
onds) and then goes out again; now re-
lease the accelerator pedal.
5) The warning light will begin to
flash: after it has flashed for the same
number of times as the second digit on
the code of the CODE card, press com-
pletely and hold down the accelerator
pedal.

6) Repeat this procedure in the same
way for the other digits on the CODE card
code.
7) After entering the last figure, keep
the accelerator pedal pressed. The warn-
ing light turns on (for four seconds)
and then goes off; now release the accel-
erator pedal.
8) A quick flash of the warning light
(for appr. 4 seconds) confirms that
the operation has taken place correctly.
9) Start the car turning the ignition key
from the MARposition to the AVV po-
sition without returning the key to the
STOPposition.
Conversely, if the warning light
stays on, turn the ignition key to STOP
and repeat the procedure starting from
point 1).
IMPORTANTAfter emergency start-
ing it is advisable to turn to an Alfa
Romeo Authorized Service, because the
procedure described must be repeated
each time the engine is started.

FUSES AND RELAYS IN THE
CONTROL UNIT
The fuses for the main devices are
housed in a control unit under the dash-
board, to the left of the steering column.
Access to it is gained slackening the
knob (A-fig. 84) and lowering the pan-
el (B).
The graphic symbols which distinguish
the main electric component correspond-
ing to each fuse are given on a label on
the inner wall of the panel.In the upper part of the control unit
there is a pincer (C-fig. 85) for remov-
ing fuses.
At the sides of the control unit there are
some spare fuses (C-fig. 86); after re-
placing a fuse you are advised to replen-
ish the stock of fuses when they are
used.
The systems and devices protected by
fuses are in listed in the tables on next
pages.The circuits operated by relays are the
following (fig. 86):
A- Switch discharge relay
B- Headlight washer timer.
