How to start the ISTA workshop system:
Double click the
BMW diagnostic software
ISTA+ icon in the Windows desktop created during the installation
process above. After ISTA is started, the start screen appears. A list
of news is displayed. You can set the display period in the
Administration.
Once
you have read the “Note on using ISTA”, close the dialog using the
button “Next”. You can open a process from the start screen: Select the
“Operations” menu.
SELECTING A VEHICLE WITHOUT CABLE CONNECTED TO CAR
Method 1:
You
can enter your short VIN (Last 7 of the VIN) and be able to pull
relevant procedures or troubleshooting instructions without actually
connecting to the car. To access this feature, launch ISTA+ and click on
Operations tab (1). Then enter the short VIN into the VIN box (2). Then
click on Accept (3). The Accept button will become active only when a
VIN number is entered. You can explore features specific to your car
from here.
Method 2:
Follow the steps as in the picture below:
SELECTING A VEHICLE VIA “READ OUT VEHICLE DATA” WITH CABLE CONNECTED TO CAR
After
you select the “Operations” menu from the start screen, the workshop
system changes to the “Vehicle identification number” tab under the
“New” menu item.
We will assume that you have connected the right
interface to the car at this time (Refer to interfaces section). Our
example will use
BMW ICOM A2+B+C.
This is how to identify a vehicle by reading out the vehicle data, while automatically creating a process:
1 Click the “Operations” main menu item in the navigation area.
2 Select the “Read out vehicle data” tab and follow the instructions provided.
3 Click the “Identification without vehicle test” or “Complete identification”button
The
connection to the vehicle is now established. The workshop system
performs an identification of the vehicle. It also reads the vehicle
identification number and further data from the vehicle. The progress of
the identification operation is displayed on a progress bar.
Start vehicle test
If
vehicle identification was called up via “Read out vehicle data” and
“Complete identification”, the vehicle test starts automatically
following vehicle identification, followed by the vehicle operation and
service data transfer and analysis. The control unit tree is displayed
during the vehicle 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”
mask 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. The control units are identified
in succession and their fault memories are read out. The color then
changes to display of the detected state. An explanation of the colors
can be found in the lower section of the displayed mask. 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:
1 Wait until the vehicle test is completed.
2 Click the “Display fault memory” button.
Show fault memory
After
the vehicle test, click the “Display fault memory” button in the “Fault
memory” mask. The fault codes that are read out and the associated
description are listed here.
The
function “Delete fault memory” can be carried out at the end of the
guided troubleshooting. In order to start the guided troubleshooting,
first calculate a test plan.
This is how to calculate a test plan:
Click the “Calculate test plan” button.
Processing the test plan
The
test plan lists the components and functions that might have caused the
fault. The documents and test modules corresponding to the components
and functions are displayed in the “Type” column, identified with “ABL”.
In the “Type” column, documents and test modules are identified with an
abbreviation.
Procedures localize a fault and give advice on rectifying it. This is how you start a procedure:
1 Select the required procedure from the test plan.
2 Click the “Display” button.
The
priority in the test plan does not necessarily specify the call-up of
the processes. The priority is to be regarded as a recommendation for
processing.
A test module is primarily designed to identify the
cause of a fault. Furthermore, service functions can be performed via
procedures. Information can be displayed within a test module, as well
as measured values read out or entered. Furthermore, queries can be made
available in procedures via selection screens.
After a test
module has been carried out, additional information is added to the test
plan if this is necessary for further troubleshooting or fault
elimination.
After the test plan has been completed, you should carry out the “Delete fault memory” function.
