ABS Anti-lock Brake System – The system that
monitors the amount of brake pressure and
individual wheel speed to assist in a hard
braking situation. ABS essentially pumps the
brakes for you to prevent wheel lock-up, which
keeps the vehicle under control.
Aero – The high performance meets high-end
luxury form. Aero for 2002 is more aggressive
and sportier. Aero has been a nameplate for
Saab since MY 1993.
Ah Amp hour – A rating used to classify the
strength of a battery.
AHL Automatic Headlamp Leveling – The
system that maintains the appropriate angle of
the beam emitted by the new Bi-Xenon lights. It
will adjust up or down, as necessary, based on
the load forces being placed on the front and
rear of the vehicle (e.g. going up a steep
driveway, the AHL will adjust the lamps down to
keep them on the driving surface).
AON Average Octane Number – A number
used to rate the quality of fuel (e.g. 87, 89, 92,
etc.).
Arc – The touring edition of the form names.
The next progression in the level of luxury and
comfort. This form essentially replaces the SE
model in the model designations.
ATF Automatic Transmission Fluid – A lubricant
required for the proper operation of the
automatic transmission.
A-Pillar – The front structure of the vehicle that
the windshield fits into. The A-Pillar has
reinforced beams to assist in a front impact
collision and is a crucial part of the safety cage
construction, which greatly effects the structural
rigidity of the passenger compartment.
BBS – The supplier used by Saab for the new
wheels on the 9-5 Arc 3.0t and the 9-5 Aero.
B-Pillar – The middle beam connecting the roof
to the rest of the vehicle. The front doors latch
into and the rear doors are hinged from the B-
Pillar. The B-Pillar is reinforced and is a crucial
part of the safety cage construction and the
structural rigidity of the vehicle. The B-Pillar is
Pendulum-styled on all hardtop vehicles.
Convertibles do not have a B-Pillar, and
therefore do not have a Pendulum B-Pillar.
CCA Cold Cranking Amp – A rating used to
classify the strength of a battery in cold weather
conditions. It is measured at 32 degrees
Fahrenheit.
C-Pillar – The rear pillar connecting the roof to
the rest of the vehicle on a Sedan. The C-Pillar
is reinforced and is a crucial part of the safety
cage construction and the structural rigidity of
the vehicle. Convertibles do not have a C-Pillar.
Databus – The system that allows the ECMs to
communicate to one another if necessary.
Electronic signals are sent “on the bus” with
instructions or notifications of certain on-board
changes.
DICE Dashboard Integrated Central Electronics
– An ECM which is responsible for many of the
lighting circuits on the vehicle (e.g. headlamps,
turn signals, etc.). DICE is also responsible for
activating the AC system compressor. DICE
acts as the gateway for the databus system,
meaning Tech 2 uses this system to
communicate with the other ECMs.
DTC Diagnostic Trouble Code – The code that
identifies a fault or failure. The DTCs are stored
in the memory of the respective ECM and can
be read using the Tech 2 device.
D-Pillar – The rear pillar connecting the roof to
the rest of the vehicle on a SportWagon and a
3D/5D. The D-pillar is reinforced and is a crucial
part of the safety cage construction and the
structural rigidity of the vehicle. Convertibles do
not have a D-Pillar.
ECM Electronic Control Module – A
microprocesser that has its own area of
responsibility. Each ECM monitors and adjusts
for optimal performance in its specific area.
Most ECMs communicate via a databus system.
ESP Electronic Stability Program – A system
that uses the brake system and throttle to help
correct for Oversteer and Understeer in
abnormal driving conditions, (i.e. crash
avoidance).
