MPEM — MULTI-PURPOSE ELECTRONIC MODULE
Power Distribution
The MPEM distributes power from battery to all accessories and the EMS ECU. Accessories are protected
by fuses integrated in the MPEM. Fuse ratings is identified besides their holder.
IMPORTANT:
Some components are continuous-
ly powered with the supply from the battery
through MPEM.
The EMS ECU switches the
ground to complete the electrical circuits it con-
trols.
Take this into account when troubleshooting
the electrical system. Refer to the illustration at
the beginning of this section.
Gauges Current Supply
When installing the safety lanyard, it activates the
reading of gauges without the engine running. It
will give access to most functions of the informa-
tion center gauge without starting the engine.
Gauges are supplied with current whenever the
safety lanyard cap is installed on its post.
NOTE:
The fuel pump will be activated for 2 sec-
onds to build up pressure in the fuel injection sys-
tem, only when connecting the safety lanyard cap
to the post.
Low-Fuel Level Warning Device
When the fuel level in the reservoir is low, the fuel
level sensor transmits a signal to the MPEM. The
MPEM sends out signals to the beeper and to the
information center gauge.
Monitoring System
The EMS ECU monitors the electronic compo-
nents of the fuel injection system and also the en-
gine components of the electrical system.The
MPEM monitors the vehicle electrical system and
the accessories. When a fault occurs, it sends vi-
sual messages through the information center
and/or audible signals through a beeper to inform
you of a particular condition. Refer to the DIAG-
NOSTIC PROCEDURES section for the displayed
messages and the beeper coded signals chart.
Addition of Accessories
Every time an accessory is added such as an elec-
tric bilge pump or a VTS for instance, it must be
“registered” using B.U.D.S. to activate it in the
MPEM. Otherwise, the accessory will not work.
Use the

area in the
