Adjustment

Using the Intelligent Saab Tester (ISAT), It is possible to adjust the display of a number of parameters. The ISAT reads a programmed value and presents this. If you do not wish to adjust this, end the routine with ESC.

Make a habit of switching the ignition off and then on when verifying any action.

Important
When the ISAT is carrying out adjustment, the Electronic Display Unit (EDU) can flash and the gauges fluctuate. This is perfectly normal.






FUEL REMAINING
Using the adjustment command "FUEL REMAINING", it is possible to adjust the fuel gauge offset. This means that an increase in fuel remaining moves the whole scale up/down comparatively in steps of 0.52 l (rounded to one decimal).

This adjustment is made when size of the deviation in the fuel gauge is the same from empty tank to full tank. When reading "TANK CONTENTS" the same change will be read that is programmed under "FUEL REMAINING".

For example: Read "TANK CONTENTS".
Result: 52 l.
Adjusting the fuel remaining: + 5 l.
A new reading of "TANK CONTENTS" gives 57 l

Important
Use this command with careful consideration.
If the display needs to be adjusted more than ± 7 l, the fault is somewhere else.
Conduct fault diagnosis and remedy the fault.






OUTDOOR TEMPERATURE
Using the adjustment command "OUTDOOR TEMPERATURE", it is possible to adjust the display of the outside temperature on the EDU display in steps of 0.35° C (rounded to one decimal).

The pre-programmed value is 0.0°.






TANK/DTE
Using the adjusting command "TANK/DTE", it is possible to adjust the display of range with remaining fuel.

Example: An increase of 2 liters in TANK/DTE results in the range counter showing 0 km with 2 liters more remaining fuel than before.

The pre-programmed value is +2.0 l.






FUEL GAUGE
Using the adjustment command FUEL GAUGE", it is possible to change the break points of the fuel gauge. The fuel gauge has 6 break points: 0 l,10 l 20 l(1/4), 35 l(1/2), 50 l(3/4) and 68 l(F).

Because the value between two break points is automatically estimated, a faulty reading in a certain interval can be remedied.

Do as follows: - Read TANK CONTENTS with the ISAT.
- Check where the pointer is and compare.
- Activate other values with the "FUEL GAUGE" command, that is to say those values that test the whole scale.
Use the break points.
- Note that if the error is constant over the whole scale, the "FUEL REMAINING command should be used.
- If there is an error in one particular area, adjust the lower value.
Example: Error in the 10 - 20 l interval.
Adjust the 10 l break paint.
- Verify the adjustment.

Example: Activate "FUEL GAUGE".
Tap in 10 l if the displayed value is 14 l.
Adjust the fuel gauge at break point 10 l to 14 l.
Verify the adjustment by activating "FUEL GAUGE".
