<h2 id="c0">Welcome</h2>

<p>Welcome to the EDT help file.</p>

<h3>Overview</h3>
<p>The EDT screen consists of these elements:</p>
<ul>
	<li>the <a href="#c1">engine compartment</a></li>
	<li>the <a href="#c20">menu</a> (top left)</li>
	<li><a href="#c2">tool windows</a> (top right toolbar, or floating windows when active)</li>
	<li><a href="#c3">other tools</a> (bottom left toolbar)</li>
	<li>a <a href="#c17">shortcut to battery</a> (bottom right icon)</li>
</ul>


<h2 id="c1">Engine compartment</h2>

<p>All work on the engine management system is performed in the engine compartment.</p>

<p>When no <a href="#c20">menu</a> item is active, the cursor in the engine compartment can have different shapes:<p>
<ul>
	<li>magnifying glass with a plus symbol in it (click too zoom in)</li>
	<li>magnifying glass with a minus symbol in it (click too zoom out)</li>
	<li>arrow to the left, right, top or bottom (click to pan in that direction)</li>
	<li>hand (click to take apart a component, to put it together again or to alter its position)</li>
</ul>
<p>You can only establish <a href="#c7">wire</a> and <a href="#c18">measurement connections</a> when the view is completely zoomed in, on a component.</p>


<h2 id="c20">Menu</h2>

<p>
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.</p>

<p>
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.<p>

<p>
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.</p>

<ul>
	<li><a href="#c9">(Dis)Assemble</a></li>
	<li><a href="#c10">Cut</a></li>
	<li><a href="#c11">Tap</a></li>
	<li><a href="#c12">Listen</a></li>
	<li><a href="#c13">Clean</a></li>
	<li><a href="#c14">Push</a></li>
	<li><a href="#c15">Fill up</a></li>
	<li><a href="#c16">Replace</a></li>
	<li>Exit</li>
</ul>

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


<h3 id="c9">(Dis)Assemble</h3>

<img src="images/monteren.png" class="right" alt="(dis)assemble" />

<p>
With this cursor tool several components can be assembled or disassembled. The cursor operates as a screwdriver, plier or wrench.</p>

<p>
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.</p>

<p>
Some components that can be (dis)assembled with this tool are:</p>

<ul>
	<li>spark plugs</li>
	<li>idle valve</li>
	<li>magnetic pickup</li>
	<li>speed sensor</li>
	<li>several air hoses</li>
	<li>fuel lines on the fuel rail</li>
</ul>

<h3 id="c10">Cut</h3>

<img src="images/knippen.png" class="right" alt="cut" />

<p>
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 <a href="#c7">wire</a> to the points that were connected by the original wire.</p>


<h3 id="c11">Tap</h3>

<img src="images/tikken.png" class="right" alt="tap" />

	<li>Diagnosis wizard</li>
</ul>

<p>Note: not all tools may be available.</p>

<h3 id="c4">Dashboard</h3>

<img src="images/dashboard.png" class="right" alt="dashboard" />

<h4>Interface elements</h4>

<p>The dashboard contains two interface elements:</p>
<ul>
	<li>accelerator pedal (drag with mouse)</li>
	<li>ignition switch (drag with mouse)</li>
</ul>
<p>
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.</p>

<h4>Meters and warning lights</h4>

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

<p>The bottom of the dashboard contains warning lights, from left to right:</p>

<ul>
	<li>coolant temperature</li>
	<li>check engine</li>
	<li>dynamo</li>
	<li>oil pressure</li>
	<li>fuel level</li>
</ul>

<p>Meters and lights only operate when the ignition is switched on.</p>


<h3 id="c5">Multimeter</h3>

<img src="images/multimeter.png" class="right" alt="multimeter" />

<h4>Interface elements</h4>

<p>The multimeter contains these interface elements:</p>
<ul>

	<li>rotary switch (drag or click)</li>
	<li>test leads (drag to connection point in engine compartment)</li>
	<li>sockets (click to move red test lead)</li>
</ul>

<p>By dragging the test leads <a href="#c18">measurement connections</a> can be established and removed. When a test lead is connected to a point in the engine compartment that is invisible, a <a href="#c19">teleporter</a> appears.</p>

<h3 id="c21">OBD tester</h3>

<img src="images/obd.png" class="right" alt="OBD tester" />

<h4>Interface elements</h4>

<p>The OBD-tester contains these interface elements:</p>
<ul>
	<li>on/off switch (click)</li>
	<li>navigation buttons (click)</li>
</ul>

<p>
To use the tester the ignition has to be switched on, otherwise there is no communication with the control unit.</p>

<h4>Menu</h4>

<p>The tester performs three functions:</p>
<ul>
	<li>Live data<br />
	With this function sensor and actuator values can be read out. Use the navigation buttons to select an item.</li>
	<li>Read out fault codes<br />
	This function shows all stored fault codes. Use the navigation buttons to scroll through the list if necessary.</li>
	<li>Erase fault codes<br />
	This function erases all stored fault codes.</li>
</ul>


<h3 id="c6">Test lamp and LED tester</h3>

<img src="images/led.png" class="rigkht" alt="LED-tester" />

<p>
The test lamp and the LED tester have one measurement lead that can be dragged to establish a <a href="#c18">measurement connection</a>. When the lead is connected to a pin that is invisible in the current view of the engine compartment, a <a href="#c19">teleporter</a> appears.</p>

<p>
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.</p>


<h3 id="c7">Wires (fused and unfused)</h3>

<img src="images/wire.png" class="right" alt="Wires" />

<p>
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 <a href="#c19">teleporter</a> appears.</p>
</p>

<p>
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.</p>

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

<h4>Fuse</h4>

<p>
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.</p>



<h2 id="c3">Other tools</h2>

<p>
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.</p>

<p>These tools are available (from left to right):</p>

<ul>
	<li>compression meter (drag to spark plug hole, spark plug has to be disassembled)</li>
	<li>test spark plug (drag to spark plug hole, original spark plug has to be disassembled)</li>
	<li>jump starer (drag to battery)</li>
</ul>

<p>Note: not all tools may be available.</p>


<h2 id="c17">Shortcut to battery</h2>


<img src="images/accu.png" class="right" alt="Shortcut to battery" />

<p>
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.</p>


<h2 id="c18">Measurement connections</h2>

<p>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 <a href="#c19">teleporter</a> appears.</p>

<p>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.</p>


<h2 id="c19">Teleporter</h2>

<img src="images/teleporter.png" class="right" alt="teleporter" />

<p>
A teleporter visualizes 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.</p>
