## Welcome

Welcom to the EDT help file.

### Overview

The EDT screen consists of these elements:

- het engine compartment
- het menu (top left)
- tool windows (top right toolbar, or floating windows when active)
- other tools (bottom left toolbar)
- een shortcut to battery (bottom right icon)

## Engine compartment

All work on the engine management system is performed in the engine compartment.

When no menu item is active, the cursor in the engine compartment can have different shapes:

- magnifying glass with a plus (click too zoom in)
- magnifying glass with a minus (click too zoom out)
- arrow to the left, right, top or bottom (click to pan in that direction)
- hand (click to take apart a component, to put it together again or to alter its position.

You can make wire and measurement connections when the view is completely zoomed in on a component.

## Menu

In the left top corner of the screen is the menu. It contains cursor tools: by clicking a menu item, special tasks can be perfomed in the engine compartment.

When a menu item is selected the cursor changes shape. The selected task can only be performed on those places in the engine compartment where a star appears in the cursor.

E.g. by selecting 'fill up', the cursor changes to a fuel can. When this fuel can is moved to the opened fuel filler door, a star appears. By clicking the left mouse button, the fuel tank gets filled up.

- Clean
- Push
- Fill up
- Replace
- Exit

When "exit" is selected, the program is being terminated. You have to specify what the diagnosis is and what further action is necessary.

### (Dis)Assemble

With this cursor several components can be assembled or disassembled. The cursor operates as a screwdriver, plier or wrench.

Components that can be disassembled manually (like a connector or a ignition cable), can be disassembled without this cursor. The cursor is only used on components that in reality require a tool to disassemble.

Some components that can be (dis)assembled with this tool are:

- spark plugs
- idle valve
- magnetic pickup
- speed sensor
- several air hoses
- fuel lines on the fuel rail

### Cut

With this cursor you can cut wires at a connector. A piece of wire that has been cut dissappears. Once a wire has been cut, the connection can only be restored by connecting a new wire to the points that were connected by the original wire.

### Tap

You can unstick sticky relays with this cursor.

### Listen

Use this cursor to listen to various components with a stethoscope.

You can listen to these components:

- injectors
- fuel rail
- fuel pump

### Clean

You can clean connectors with this cursor. This will solve a bad connection or contact resistance.

Other components that can be cleaned are:

- spark plugs
- idle valve
- magnetic pickup

You can also use this cursor to spary startpilot. You need to lift the air filter box cover or remove a hose on the intake manifold.

### Push

You can push connectors with this cursor, to make a bad connection temporarily working.

### Fill up

You can fill up the fuel tank with this cursor.

You can also use this cursor to spary startpilot. You need to lift the air filter box cover or remove a hose on the intake manifold.

### Replace

You can replace fues with this cursor. All other components need to be 'ordered' at the end of the program.

## Tool windows

The top right toolbar opens tool windows. When you click an icon, a floating tool window appears. This window remains visible, when you move to another view in the engine compartment. You can moev the window to any location by dragging it with the mouse. The tool dissappears by clicking the small rectangular button "x".

These tools are available (from top to bottom)::

- Dashboard
- Multimeter
- OBD Tester
- Test Lamp
- LED Tester
- Wires
- Diagnosis wizard

Note: not all tools are available in all failure simulations.

### Dashboard

#### Interface elements

The dashboard contains two interface elements:

- accelerator pedal (drag with mouse)
- igntion switch (drag with mouse)

You can also operate the ignition switch using keyboard shortcuts. By pressing the space bar the switch is set to the start position, when you release the space bar it is set to ignition position. The switch is set to the off position by pressing the shift key.

#### Meters and warning lights

The dashboard contains meters for coolant temperature, engine speed (RPM) and fuel level.

The bottom of the dashboard contains warning lights, from left to right:

- coolant temperature
- check engine
- dynamo
- oil pressure
- fuel level

Meters and lights only operate when the ignition is switched on.

### Multimeter

#### Interface elements

The multimeter contains these interface elements:

- on/off switch (click)
- AC/DC switch (click)
- rotary switch (drag or click)
- test leads (drag to connection point in engine compartment)
- sockets (click to move red test lead)

By dragging the test leads measurement connections can be made and removed. When a test lead is connected to a point in the engine compartment that is invisible, a teleporter appears.

### OBD tester

#### Interface elements

The OBD-tester contains these interface elements:

- on/off switch (click)
- navigation buttons (click)

To use the tester the igntion has te be switched on, otherwise there is no communication with the control unit.

#### Menu

The tester perfoms three functions:

- Live data
  With this function sensor and actuator values can be read out. Use the navigation buttons to select an item.
- Read out fault codes
  This function shows all stored fault codes. Use the naviagation buttons to scroll through the list if necessary.
- Erase fault codes
  This function erases all stored fault codes.

### Test lamp and LED tester

The test lamp and the LED tester have one measurement tip that can be dragged to make a measurement connection. When the tip is connected to a pin that is invisible in the current view of the engine compartment, a teleporter appears.

The position of the test lamp determines if the tip is connected to a pin. The colour of the tip indicates if it is connected. When you navigate to a different view in the engine compartment (e.g. zoom out), the connection of the tip is lost.

### Wires (fused and unfused)

Wires contain two copper ends that can be dragged to create a wire connection. When a wire end is connected to a pin that is invisible in the current view of the engine compartment, a teleporter appears.

Wires that are connected to the backside of a connector remain connected when the connector is taken apart. Wires that are connected to the inside of a connector are disconnected when the connector is put together again.

A connected wire is removed by clicking the close button (small button 'x' at the top).

#### Fuse

When a wire is fused, the fuse is inspected by clicking on it. The fuse then is lifted form its socket. Broken fuses can be replaced by selecting 'replace' from the menu and clicking on the fuse.

## Other tools

The bottom left toolbar contains tools, that remain in the engine compartment when they are used. The tool's icon is dragged to a location in the engine compartment. When the mouse button is released, the tool appears. The tool is removed by clicking on it.

The tools are available (from left to right):

- extra fuel pump (drag to the original fuel pump in the tank)
- compression meter (drag to spark plug hole, spark plug has to be disassembled)
- test spark plug (draf to spark plug hole, orginal spark plug has to be assembled)
- jump starer (drag to battery)

Note: not all tools are available in all failure simulations.

## Shortcut to battery

For quick access to the battery, you can click on the button in the bottom right corner. At the battery this button changes in a 'back'-button to return to the place you came from.

## Measurement connections

A test lead can be dragged to create a connection. When the test lead is connected to a pin that is invisible in the current view of the engine compartment, a teleporter appears.

Measurement connections are disconnected when the test lead is removed, the tool is removed (with the close button) or when the connector to which the test lead is connected is taken apart or put together.

## Teleporter

A teleporter visualises an electrical connection to a pin that is invisible in the current view of the engine compartment. When you click on a teleporter, you return to the view where the pin is visible. When you connect a wire to the backside of a connector and then take the connector apart, a teleporter also appears. The teleporter dissappears when you put the connector together again.
