Control Module
The Electronic Display Unit (EDU) 3 programmable trip computer has two versions; version A for cars with automatic transmission and version M for
cars with manual gearbox.
Both versions are programmable for different car models.
It is possible to select how the information is presented using the INFO and the R buttons. The EDU control module can be checked for faults and
programmed using the Intelligent Saab Tester (ISAT).
The trip computer is controlled by a central unit (CPU - Central Processing Unit) which is controlled by the EDU program stored in the ROM (Read
Only Memory) memory.
-
User programming information is stored in EEPROM (Electrically Erasable PROM) and the information remains stored even if the voltage supply
is broken.
-
EEPROM is also used to store data and diagnostic trouble codes. The information remains in the memory if the voltage drops.
The trip computer is supplied voltage with +30 and +15.
The LCD display is illuminated (1) by three lamps mounted on the rear of the computer.
When driving in the dark, the lighting is controlled by the rheostat (2).
When driving in daylight, light is measured by a light sensor (3) on the Saab Car Computor (SCC) unit or on the front of the clock and controls, using
this information, the EDU display lighting.
