SCC Trip Computer
DESCRIPTION OF OPERATION
The SCC trip computer (Saab Car Computer) has the following functions:
(left-hand side ^)
^
DIST. TO DEST. (distance to destination).
^
AVER. SPEED (average speed).
^
SPEED WARN. (speed warning).
(right-hand side >)
^
CLOCK (clock function).
^
ARRIVAL (arrival time).
^
ALARM (alarm function).
The trip computer is operated by means of the buttons situated below the display. Presentation in kilometers or miles can also be selected with
these buttons.
SCC Trip Computer
The bottom row on the trip computer includes a light sensor and two buttons. The light sensor is used for automatic control of the brightness of the
SCC and EDU trip computer displays in daylight.
The brightness of the button illumination is controlled by rheostat 16 (lighting for instruments and controls) on the dashboard.
SCC trip computer 241 is supplied with current from fuse 19 continuously and also from fuse 13 when the ignition switch is in the Drive position.
R and INFO are used for the EDU trip computer. Together with the light sensor they are connected to EDU trip computer 210 via an 8-Pin
Connector.
To process and display the information for the different functions, the trip computer needs data on the speed of the car. This is obtained from
vehicle speed sensor 132 via the EDU.
FAULT DIAGNOSIS HINTS
The trip computer is activated by turning the ignition switch to the Drive position.
1. Check that fuses 13 and 19 are intact and supplied with current.
2. Check that current is supplied to pin 1 of the trip computer, via clock 49 and pin 6.
3. Check that current is supplied to terminal 1 of vehicle speed sensor 132 and then from terminal 2 of the vehicle speed sensor to terminal 9
of the EDU trip computer.
4. Check that current is supplied from the EDU to the SCC.
5. Check that the contact surfaces of the connectors are undamaged and clean. This is important as the currents involved are weak.
6. Check the wiring harness and ground connections.
