Section 05 ELECTRICAL SYSTEM
Subsection 02 (POWER DISTRIBUTION)
If B.U.D.S. is being used for communicating with
the electronic modules, or if the information cen-
ter must be ON for testing, selecting modes of
operation, changing key settings, or for other
functions accessed through the information cen-
ter, the D.E.S.S. key must be installed.
NOTE: To prevent the electrical power from
shutting down after approximately 3 minutes,
press the START button before the three minute
power-up period ends.
TROUBLESHOOTING
DIAGNOSTIC TIPS
NOTE: It is a good practice to check for fault
codes using B.U.D.S. software as a first trou-
bleshooting step. Refer to
COMMUNICATION
TOOLS AND B.U.D.S. SOFTWARE
subsection.
IMPORTANT: When troubleshooting an electrical
system fault, check battery condition, cables and
connections first.
Circuit Testing
Check the related-circuit fuse condition with a
fuse tester or ohmmeter. A visual inspection on
its own could lead to an incorrect conclusion.
Electrical Connection Inspection
When replacing an electric or electronic compo-
nent, always check electrical connections. Make
sure they are tight, make good contact, and are
corrosion-free. Dirty, loose or corroded contacts
are poor conductors and are often the source of a
system or component malfunction.
Pay particular attention to ensure that pins are not
bent or pushed out of their connectors.
Ensure all wire terminals are properly crimped on
wires, and connector housings are properly fas-
tened.
Check for signs of moisture, corrosion or dullness.
Clean pins properly and coat them with
DIELEC-
TRIC GREASE (P/N 293 550 004)
or other appropri-
ate lubricant (except if otherwise specified) when
reassembling them.
Pay attention to ground wires.
Fuse Inspection
If an electrical system fault occurs, check the
fuses. If a fuse is burnt, replace it with a fuse of
the same rating.
Keep in mind that an electrical component may
require more than one fuse, one low amperage
rated fuse for its control circuit, and another higher
rated fuse for the main component power. These
two fuses may not be in the same fuse box.

A visual inspection of a fuse may not be conclu-
sive.
Two metal contacts are visible at the top of the
fuses. They can be used for testing the fuse us-
ing a fuse tester or a multimeter. They can also be
used for testing the circuit the fuse protects with-
out removing the fuse.
However, when testing a fuse using an ohmme-
ter, the fuse should always be removed from the
fuse box.
WARNING
When replacing a fuse, do not use a higher
rated fuse than recommended. Use of a
higher rated fuse can lead to severe compo-
nent or circuit damage, an overheat condi-
tion, and possibly and electrical fire. If a fuse
has burnt out, the source of the malfunction
should be identified and corrected before
applying power to the vehicle.
TESTING SEQUENCE
Electrical Power Does Not Come ON
Electrical system power up is normally identified
by the information center powering up and cycling
through its self-test function.
If the information center does not come on, check
the following:
– Ensure battery is properly connected.
– Check the BATT. fuse in FB2.
– Check for activation of the power relay in FB2.
