GxT Ferret 54 ENGINE DIAGNOSTIC CENTER - Manual (Page 26)

SETUP
The setup menus provide an easy way for you to tell the Diagnostic Center about the engine
being tested and to set preferences. Menus will change according to choices already made.
For example, if a 5-cylinder engine is selected,
DIS Double End will not appear as an available
ignition type. Available tests will also depend on the engine described during Engine Setup .
Use SELECT to move the cursor to your selection. Pressing NEXT will enter the selection
and move to the next menu. If an error is made, press SETUP and reenter your selections.
Engine Setup
The Engine Setup provides the Diagnostic Center with information about hookup and the vehicle
to be tested. Use the SELECT keys to move the cursor, and press NEXT to enter the selection.

SELECT the number of cylinders, and press NEXT. A new screen will appear, offering a choice
of ignition type.
DISTRIBUTOR NON-DISTRIBUTOR
Separate Coil Diesel
Integral Coil DIS Coil/Plug
No Coil (-) Wire DIS Dbl
Distributor ignitions will have a Separate Coil or an Integral Coil , where the coil is inside the
distributor housing (like GM HEI). In some cases, as with many Nippondenso ignitions, the
Coil (-) wire is not accessible. In that case, SELECT
No Coil (-) Wire.
Non-Distributor ignitions include Diesel engines, DIS Coil/Plug, and DIS Dbl End (double end
or output) where each coil fires two plugs at the same time.
SELECT the ignition type, and press NEXT. Select 4 or 2 strokes, and select the firing order.
Choosing a firing order causes test data to be displayed in cylinder block number sequence.
If the default is accepted, e.g., 1 2 3 4, the results will be displayed in firing order sequence.
Emissions Setup
If the Gas Detector is connected, two more screens will appear:
Fuel Type
Air-Fuel ratio and Lambda are calculated from the gases measured. Both calculations are
dependent upon what fuel is being used.
Vehicle Year and Size
Bar graphs in the emissions test are scaled to the expected range for the vehicle being tested.
For the best scale, choose the category that most closely matches year and size of the car.
