Saab Information Display (SID) later also called "Saab Car Computer" [1] (SCC) is the name for various in-car computer systems found on most Saab automobiles beginning in 1985 with the Saab 9000 and followed in 1994 with the Saab 900 NG.

Saab Automobile automotive brand manufacturing subsidiary of NEVS

Saab Automobile AB was a manufacturer of automobiles that was founded in Sweden in 1945 when its parent company, SAAB AB, began a project to design a small automobile. The first production model, the Saab 92, was launched in 1949. In 1968 the parent company merged with Scania-Vabis, and ten years later the Saab 900 was launched, in time becoming Saab's best-selling model. In the mid-1980s the new Saab 9000 model also appeared.

Saab 9000 car model manufactured by Saab

The Saab 9000 is an executive car that was produced by the Swedish company Saab from 1984 to 1998. Representing the company's foray into the executive car scene, it was developed as a result of the successes of the turbocharged 99 and 900 models. The 9000 remained in production until it was replaced by the Saab 9-5 in late 1997, although some final cars were produced into 1998.

SIDs typically provide functions useful to the driver such as multiple trip odometers, fuel efficiency, estimated range ("distance to empty" – DTE), current CD track or radio station, and also brief description of car system failures. SIDs designed prior to the full General Motors takeover of Saab in 2000 were mounted in the center console, usually just above the head unit and below climate control vents with the exception of 9000 models, possibly after the "facelift" in the early 1990s.

Trip computer

A trip computer is a computer fitted to some cars; most modern trip computers record, calculate, and display the distance travelled, the average speed, the average fuel consumption, and real-time fuel consumption.

Odometer instrument that indicates distance traveled by a vehicle

An odometer or odograph is an instrument used for measuring the distance travelled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two. The noun derives from the Ancient Greek word οδόμετρο from odós, οδός and métro, μέτρο ("measure"). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometer, the former name especially being prevalent in the United Kingdom and among members of the Commonwealth.

Fuel efficiency is a form of thermal efficiency, meaning the ratio from effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process.

The 9000 featured the SID on the standard instrument cluster, with a car pictogram, showing open doors/tailgate/boot (trunk), lamp failures and low oil pressure in red. If there were no warnings, the white pictogram would disappear. To the right of this was the data display in orange with green background data. This constantly showed instantaneous fuel consumption on an orange moving bar display with other parameters to its left such as alternator voltage, battery cranking voltage during start, outside temperature, estimated fuel range and average fuel consumption, cycled through by pressing an INFO button on the clock on the dashboard. Also displayed were engine check warnings. In addition, the analogue electric clock module could be replaced by a digital unit that scrolled SAAB across the orange LED display on startup before showing the time. This display featured digital trip functions such as distance to destination, average speed, estimated arrival time and adjustable speed warning settings, cycled through and set by pressing several buttons and retaining the R (reset) and INFO button for the instrument cluster. When fitted, the automatic climate control (as opposed to simple air conditioning) showed the selected temperature on green LEDs on the ACC unit fitted in the centre console in degrees C or F, selected by a nearby slide switch. Heated rear window (repeated on the main instrument cluster), heated door mirrors, ventilation outlet selections (including rear side window demist) and ACC mode were also indicated on the ACC unit by green LEDs next to the selector buttons (orange for the electrically heated items). Audio functions were displayed on the head unit, also in the centre console, such as FM Radio Station Name where RDS was available (otherwise just the Radio Frequency) on a green LCD. CD track info was similarly displayed on the console mounted single CD player, where fitted, on its own green LCD. The 9000 SID was not noted for pixel failures since it appears not to be LCD based. Where a CD "pack" was fitted, it is assumed the track info would be displayed on the head unit. Reference: from personal ownership.

Pictogram ideogram that conveys its meaning through its pictorial resemblance to a physical object

A pictogram, also called a pictogramme, pictograph, or simply picto, and in computer usage an icon, is an ideogram that conveys its meaning through its pictorial resemblance to a physical object. Pictographs are often used in writing and graphic systems in which the characters are to a considerable extent pictorial in appearance. A pictogram may also be used in subjects such as leisure, tourism, and geography.

Oil pressure

Oil pressure is an important factor in the longevity of most internal combustion engines. With a forced lubrication system, oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings and camshaft bearings or balance shaft bearings. Other components such as cam lobes and cylinder walls are lubricated by oil jets.

Light-emitting diode semiconductor light source

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. This effect is called electroluminescence. The color of the light is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device.

On 2003–2005 Saab 9-3 models, the SID was temporarily moved to the top of the dashboard just below the windshield, in an enclosed hump facing the driver.

Dashboard control panel located directly ahead of a vehicles driver, displaying instrumentation and controls for the vehicles operation

A dashboard is a control panel usually located directly ahead of a vehicle's driver, displaying instrumentation and controls for the vehicle's operation.

Windshield front window of vehicle

The windshield or windscreen of an aircraft, car, bus, motorbike or tram is the front window. Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of two (typically) curved sheets of glass with a plastic layer laminated between them for safety, and are bonded into the window frame. Motorbike windshields are often made of high-impact polycarbonate or acrylic plastic.

GM began moving SIDs in all Saabs to the electronic instrument cluster, just above the steering wheel, as stock GM navigation and/or audio head units replaced the Saab-designed units in the center console. The 2005 - 2006 Saab 9-2X did not feature an authentic SID, having a less feature-rich Subaru unit instead as it was basically a rebadged 2nd generation Subaru Impreza with some styling changes.

Electronic instrument cluster

In an automobile, an electronic instrument cluster, digital instrument panel or digital dash for short, is a set of instrumentation, including the speedometer, that is displayed with a digital readout rather than with the traditional analog gauges. Many refer to it simply as a digital speedometer.

Saab Information Displays from 1994–2003 commonly suffer from an electrical system failure that results in some or all of the on-screen liquid crystal display (LCD) pixel lines becoming invisible, rendering the SID difficult to read or, in some cases, entirely unusable. The problem is most often caused not by defective pixels, but by some or all of the LCD's flexible flat cable (ribbon cable) contacts separating from the main logic board.

Defective pixel

Defective pixels are pixels on a liquid crystal display (LCD) that are not performing as expected. The ISO standard ISO 13406-2 distinguishes between three different types of defective pixels, while hardware companies tend to have further distinguishing types.

Flexible flat cable

Flexible flat cable, or FFC, refers to any variety of electrical cable that is both flat and flexible. A flexible flat cable is a type of flexible electronics. However, the term FFC usually refers to the extremely thin flat cable often found in high-density electronic applications like laptops and cell phones.

Ribbon cable

A ribbon cable is a cable with many conducting wires running parallel to each other on the same flat plane. As a result the cable is wide and flat. Its name comes from its resemblance to a piece of ribbon.

Several third party vendors offer a service to permanently fix broken SIDs, for a fee.

The frequency of the problem strongly suggests a design flaw,[ original research? ] but Saab/GM has never issued a product recall.

Electronic flight instrument system

An electronic flight instrument system (EFIS) is a flight deck instrument display system that displays flight data electronically rather than electromechanically. An EFIS normally consists of a primary flight display (PFD), multi-function display (MFD), and an engine indicating and crew alerting system (EICAS) display. Early EFIS models used cathode ray tube (CRT) displays, but liquid crystal displays (LCD) are now more common. The complex electromechanical attitude director indicator (ADI) and horizontal situation indicator (HSI) were the first candidates for replacement by EFIS. Now, however, few flight deck instruments cannot be replaced by an electronic display.
