Aerial; Code Card - Fiat Brava Service Manual

Electrical system
Fiat CODE
Bravo-Brava
55.
The key handle contains a Transponder, an electronic device NOT supplied by the battery; it contains a
code and effects transmission by ether.
When the key is inserted in the ignition switch, the Transponder is activated by the aerial by radio waves
and responds automatically by emitting a code.
Each key contains a Transponder with a secret code. The MASTER key (maroon key) contains the Mas­
ter Code and should be used ONLY for the key memorization procedure.
The code of the MASTER key is the Master Code memorized in the engine control unit and Fiat CODE
control unit; this links the engine control unit and the MASTER key so that they are inseparable. If the
MASTER key is lost or damaged, no further new key memorization procedures will be possible; a subse­
quent fault in the Fiat CODE control unit will make it necessary, in the absence of the MASTER key, to re­
place the Fiat CODE control unit and engine control unit.
The owner of the car is advised to CLOSELY follow the instructions below:
- the MASTER key must be stored in a safe place (not in the car);
- the MASTER key must be used only to memorize new keys;
- the CODE Card with the secret code must not be left in the car in case of theft; at the same
time it must be available for emergency starting;
- the MASTER key is the right of ownership of the car; if the vehicle is sold, the MASTER key
and CODE Card must be handed over to the new owner.

2. CODE Card with the secret code
Aerial
The aerial has to do the following:
- supply energy to the Transponder for sending the code;
- receive the code from the Transponder and send it to the Fiat CODE control unit.
Since the aerial has to be close to the Transponder (because of the electromagnetic immunity, small size
and limited range of action of the Transponder), it is fitted coaxially in relation to the ignition switch.
CODE Card
The CODE Card is supplied in two copies, containing the following:
- Electronic CODE, 5-digit code for the emergency starting procedure using the Fiat Lancia Tester or,
for models where this is possible, using the accelerator pedal;
- Mechanical CODE, should the mechanical part of the key need to be duplicated.
On the back of the card, there are two spaces for applying the self-adhesive labels with any remote con­
trols with the transmitter code (password).
