11 BMW Group Page 11 4 Overview and quick introduction 4.1 Starting the ISTA Client After selection the start screen appears (chapter 5.1). A list of news is displayed. You can set the display period in the Administration menu (chapter ). Fig.4-1 Start screen If the date has changed since the last time the system was activated, the "ISTA usage notes" is displayed. After reading the note, close the pop-up window by clicking the "Continue" button. You can initiate an identification operation from the start screen. This is how to initiate an identification operation for a vehicle: Select the menu "Identification". 4.2 Selecting a vehicle via "Read out vehicle data" The most reliable way of identifying a vehicle is described in this quick introduction. Identification can be achieved by reading out the vehicle data from a connected vehicle. Further information relating to the "identification" of a vehicle can be found in the chapter 5.2.

12 BMW Group Page 12 After you have selected the menu "Identification" from the start screen, the workshop system switches to the "Operations list" tab. You can obtain more detailed information on the Operation list in chapter This is how to identify a vehicle by reading out the vehicle data and automatically create an operation to do this: Click the main menu item "Identification" in the navigation area. Select the "Read out vehicle data" tab and follow the instructions provided. Click the "Start vehicle test" button. Fig. 4-2 Preparations for reading out vehicle data The Connection manager opens. The ISTA communication devices (ICOM) from the workshop are entered in the working area of the connection manager.. This is how to select the ICOM:

13 BMW Group Page 13 Determine which ICOM is connected to the vehicle to be identified. With some series, the vehicle identification number of the connected vehicle is displayed in the "Vehicle identification number" column. Select the appropriate components in the connection manager and click the "Set up connection" button. Fig. 4-3 Connection manager After the "Make connection" button is selected and clicked, the connection to the vehicle is established. The workshop system performs an identification of the vehicle. To do this, it reads out the vehicle identification number and additional data from the vehicle. The progress of the identification operation is displayed on a progress bar. 4.3 Start vehicle test If vehicle identification was called up via "Read out vehicle data and "Brief test starts, the brief test starts automatically following vehicle identification (chapter 5.2.2), followed by the vehicle operation and service data transfer and analysis. The "Control Unit Tree" mask is displayed during the brief test. (chapter 5.3.1)

14 BMW Group Page 14 Fig. 4-4 Brief test Here you can observe the ongoing determination of the control units that are fitted. If no control unit tree is available, the "Control unit list" screen (chapter 5.3.2) is displayed automatically. The control unit tree contains all the control units identified in the vehicle and displays their allocation to the relevant bus system. While the vehicle test is running, you can observe the progress on the screen. The control units are identified in succession and their fault memories are read out. The colour then changes to display of the detected state. An explanation of the colours can be found in the lower section of the displayed screen (Fig. 4-4 Brief test). From this screen, if required you can restart the vehicle test or also call up control unit functions so that you can read out measurements or activate actuating elements. Before you can access a test plan you must first display the fault memory. This is how to view the fault memory: Wait until the vehicle test is completed. Click the "Display fault memory" button. 4.4 Show fault memory

15 BMW Group Page 15 After the brief test, click on the "Fault memory" button in the "Control Unit Tree" to be taken to the "Fault memory" mask (chapter ) The fault codes that are read out and the associated description are listed here.

Only those hits are displayed that contain all search terms that had been entered.

51 BMW Group Page 51 Note Text search in the title If for example you search for the term "Engine" in the title, all documents whose title includes the term "Engine" are listed. Furthermore, all documents are added to the hit list which contain the term anywhere in their title, for example "Petrol engine", "Engine mounting", Electric engine". Note Text search in the document Specific information for individual markets is contained in the data packages in the form of pdf files. These can be displayed in ISTA. It is not possible to perform a text search in these pdf files. However, a title and document number search is supported for these documents. Note The text search cannot be used to search for procedures. Search for procedures in the function structure or in the service functions Additional information on the text search by documents Part designation In the wiring diagrams, short descriptions are used for components such as "A149a" for a control unit or "X1108" for a ground connection. The text search can only be used to find these codes in the title. All the documents that contain the entered code in their title are displayed in the hit list, for example "A149a" or "X1108". Searches by part designation within the document are not possible. The same applies to searches for engine codes such as "M54" Special tools You can start the search via the document numbers by specifying the number of the special tool (for example: ).

You can use the "Filter fault memory" function to specify the kilometre reading as a criteria. Class: This column contains the fault classes. These describe the type of fault, "Undervoltage" for example. You can use the "Filter fault memory" function to specify fault classes as a criteria. The buttons in the action line have the following functions: Display fault code: The button becomes active when a fault code has been selected. The button provides access to further information (description, details and system context see chapter ) regarding a fault code. Delete fault memory: This function is only active after a completed vehicle test (chapter 5.3). In a first step, the fault memories of all identified control units are deleted. The fault memories of all control units are then read out again.

55 BMW Group Page 55 Filter fault memory: You can use this function to filter the displayed fault memory entries according to fault classes, such as "Undervoltage" and/or "Km reading (mileage)". Delete filter: A set filter is stopped and all the read fault memory entries are displayed again. Display all: adapts the widths of all columns to their maximum text lengths. If you click the button a second time, the workshop system returns the columns to their initial widths. Calculate test plan: Starts the calculation and display of the test plan. The calculation is carried out on the basis of the existing, possibly filtered, fault memory entries and the selected fault patterns (chapter 5.5.2). Note Under certain circumstances, a number of individual faults are merged to create a socalled collective fault. If a collective fault is involved, the fault memory entries on which this is based are not displayed individually Diagnostic fault code Selecting the "Display fault code" button (Fig. 5-25) prompts a window to appear with the following tabs: Description Details and System context This functionality can also be called up from some processes that provide the possibility to investigate fault codes more precisely Description The "Description" tab is only enabled if a document is available for the selected fault code. It contains useful information on the fault code and supports you in troubleshooting.

You can use the arrow buttons to move the two cursors ("from", "to") and limit the number of fault memories. If the arrow buttons are pressed for longer, the speed of the cursor movement increases. All the fault memories that are outside the cursor are filtered away (colour: grey), whereas the fault memories within the cursor remain on display (colour: black). Activating the button again disables the cursor. Information on the individual fault codes can be displayed as follows: If you activate a fault code, the corresponding fault code description remains on display directly below the selected hex code in the form of a note until the next time the touch screen is touched. The buttons in the action line have the following functions: Cancel: Without changing the filter setting, the user is returned to the "Fault memory" mask. Accept: The current filter setting is accepted and the user is returned to the Fault memory mask. The list is prepared based on the current filter settings. Zoom in: The scale is enlarged.

60 BMW Group Page 60 Zoom out: The scale is reduced. In the workshop system, fault classes are used to filter fault codes. To this end, the workshop system evaluates existing ambient conditions and only shows the fault codes that correspond to the specified class. Fault codes without ambient conditions cannot be filtered. Fig Filtering fault memory, "Class" tab Note After filtering of the faults, only the filtered faults are used for the diagnosis to calculate the test plan. The faults stored in the control units are not changed Fault pattern In the "Fault pattern" tab; you can select fault patterns from a function structure in many levels. They supplement the read-in fault memory entries and are taken into account in test plan calculation. You should select the fault patterns independently of the customer's complaints about the vehicle. Especially for complaints outside the vehicle electrics system, the selection of fault patterns is especially important for assuring a successful diagnosis. Select "Activities - Guided troubleshooting - - Fault pattern" in the navigation area.
