## Welcome

Welcome to the EDT help file.

### Overview

The EDT screen consists of these elements:

- the engine compartment
- the menu (top left)
- tool windows (top right toolbar, or floating windows when active)
- other tools (bottom left toolbar)
- a 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 symbol in it (click too zoom in)
- magnifying glass with a minus symbol in it (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 only establish wire and measurement connections when the view is completely zoomed in, on a component.

## Menu

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

When a menu item is selected the cursor changes shape. The selected task can only be performed on those parts 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.

- Exit

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

### (Dis)Assemble

With this cursor tool 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 an ignition cable), can be disassembled without this cursor. The cursor is only used on components that in reality require a tool to disassemble them.

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 tool you can cut wires at a connector. The piece of wire that has been cut disappears. 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 tool.

### Listen

Use this cursor tool 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 tool. 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 tool as a start pilot spray. 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 tool, to make a bad connection temporarily working.

### Fill up

You can fill up the fuel tank with this cursor tool.

You can also use this cursor tool as a start pilot spray. You need to lift the air filter box cover or remove a hose on the intake manifold.

### Replace

You can replace fuses 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 move the window to any location by dragging it with the mouse. The tool disappears 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 may be available.

### Dashboard

#### Interface elements

The dashboard contains two interface elements:

- accelerator pedal (drag with mouse)
- ignition 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 established 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 ignition has to be switched on, otherwise there is no communication with the control unit.

#### Menu

The tester performs 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 navigation 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 lead that can be dragged to establish a measurement connection. When the lead 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 and the LED tester 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 can be inspected by clicking on it. The fuse then is lifted from 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 a part of 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.

These tools are available (from left to right):

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

Note: not all tools may be available.

## Shortcut to battery

For quick access to the battery, you can click on the button in the bottom right corner. At the view of 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 establish 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 disappears when you put the connector together again.
