dashboard warning lights SAAB 9-5 2004 Owners Manual

228 Car care and technical informationMaxi fusesThe Maxi fuses are housed in the fuse box
under the hood. These fuses can be
checked in the same way as the other fuses.
The Maxi fuses are designed to protect the
car’s electrical system from being dam-
aged. Each Maxi fuse protects a number of
electrical circuits and functions and there-
fore has a higher rating (amperage) than the
standard fuses. No spare Maxi fuses are
supplied with the car.
DICE / TWICEDICE = Dashboard Integrated Central Elec-
tronics
TWICE = Theft-Warning Central Electronics
DICE and TWICE are electronic control
modules that monitor and control a variety
of functions, including:
DICE controls (among other things):
 Front lights and interior lighting
 Instrument illumination
 Intermittent wiper operation
 Electric heating of rear window and door
mirrors
 Cooling fans
TWICE controls (among other things):
 Central locking.
 Car alarm (Anti-theft system)

 Autochecking of lights.
 Electric heating of rear seat
 Safety belt reminder
 Electrically adjustable passenger seatThe DICE and TWICE control modules are
linked to a data bus, which is basically an
information carrier that allows information to
be exchanged between all the control mod-
ules and components connected to the bus.
If a fault occurs in any of these components,
diagnostic faults codes are set in the rele-
vant control module, which facilitates fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTICEIf a Maxi fuse blows, it means that there is
a major fault in the electrical system.
Have the car checked without delay by an
authorized Saab dealer.
