81 Instruments and controls
The system uses five sensors:
Outside-air temperature.
Cabin-air temperature.
Sun sensor.
Blended-air temperature (located in the
heater unit).
Coolant temperature.
The sun sensor is centrally located on the
dashboard panel between the defroster
nozzles. Note that if anything is placed over
the sun sensor the ACC system will not
function properly.
Condensation water When the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form.

188 Car careMAXI 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.
DICE controls, among other things:
Front lights and interior lighting.
Instrument illumination.
Intermittent wiper operation.
Electric heating of rear window and door
mirrors.
TWICE controls, among other things:
Central locking.
Car alarm (Anti-theft system).
Engine immobilizer.
Auto checking of lights.
Electric heating of rear seat.
Safety belt reminder.
Electrically adjustable passenger seat.The 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 enhances fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTEIf 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.
