SERVICES RELAY
It is situated inside the storage compartment, underneath the ve-
hicle seat (Fig. A). The relay assembly is managed by the ECM
to control each load at best, such as:
• The lighting system
The ECM ensures that the lights turn on in certain conditions.
• The fuel pump
The fuel pump is activated only when the starter lets the engine
rotate.
• The electric fans
• The injection
The ECM controls the injection relay pull-in according to the
relevant conditions, as ignition, shutdown, and use of the vehi-
cle, thus allowing a stable supply to ECM, which can carry out
any correct procedure of storage and setting of the parameters
in the standstill phase, by continuing its self-powering for some
seconds after the instrument panel shutdown.
• Services
All devices “with ignition on”, as dashboard, various safety devic-
es and lighting system, are connected to the services relay.
