How to use ODIS software for flashing

what is ODIS flashing mode:

In addition to diagnosis, Offboard Diagnostic Information System Service  also offers the ability to flash.

The process used in Flashing mode is very similar to Diagnosis mode, but it is less comprehensive overall. Guided

Fault Finding and control module functionalities are not available in this mode.

How to do flash a control unit using ODIS:

Flashing start-up

starting a flash session

identifying a vehicle

login to group systems

selecting an order

identifying control units

Using flashing

executing flash programs

Finding flashing

ending a flash session

  • When entering the flashing process, the vehicle is connected to the tester and identified, login to the group

systems is completed, an order is selected for the session and the control modules are identified.

  • The flash programs determined for the vehicle can then be performed.
  • The flash session ends when the desired flash work is complete.

Step 1: Start flash session

Flashing entry can begin once a permitted diagnostic connection is selected and the vehicle is connected.


Step 2: Analyze the vehicle automatically


If the automatic vehicle identification fails, Offboard Diagnostic Information System Service  displays a vehicle

features dialog with entries for VIN , Manufacturer , Model  and Model year .

If the vehicle is recognized completely , meaning the VIN, brand, model and model year are clearly recognized,

vehicle identification will run completely automatically without displaying the vehicle features dialog.


Note that  You can switch between manual  and automatic  vehicle identification.


For example, the VIN can be entered and then the identification, if necessary, can run automatically. In automatic

identification, the features with a gray background cannot be changed.

Step 3: login group systems

opens a login window in order to log in.


You should have a user ID  and password  for group systems access

Step 4: order selection

If the login is successful, Offboard Diagnostic Information System Service  accesses the order data for the

current vehicle from ElsaPro .


Offboard Diagnostic Information System Service switches to the  Orders tab and shows a list of all available

orders for the vehicle.

In the work order list, the work order number is displayed under  Work order, the current status in the service core

process is displayed under  SCP status, and the vehicle  license plate number, the  deadline for the work order

and descriptive  text about the work order are also displayed.

The table that follows lists the meaning of the  SCP status numbers.


If an order from ElsaPro  will be used, the desired order must be marked here.

Select order : clicking this button continues flash entry with the order from ElsaPro .

An order can also be added manually. Standard order for working with a manual order number  is selected

in the list first.

Enter number…  : Clicking this button opens a window for entering the manual order number.

Select order:  flash entry continues with the manual order.

No order:  if you will be working without an order, click this button to continue flash entry.

Step 5: ODIS flashes programs

lists the available flash programs on the special functions tab


Clicking the desire flash program marks it.

The test programs are grouped by theme.

Perform test…:  the highlighted flash program is started. Offboard Diagnostic Information System Service

switches to the Operation  tab.

Display documents : this button can be used to display associated documents, if available. Offboard Diagnostic

Information System Service  then switches to Information  mode, Documents  tab.

The flash programs run the same way the GFF diagnostic programs run.

Step 6: diagnostic objects when flashing

In addition to the flash programs, additional functions or GFF programs, which are relevant for the vehicle, can

appear in the special function  tab. These can then be performed as the other tests.

In some cases, not all the basic features needed to perform the special function or GFF program, were transmitted

during the flash entry. If the basic features are missing, then the user will see a dialog when performing such a

test that allows the user to add the missing basic features.


The special function or the GFF program for identifying the diagnostic objects needs more information about the

equipment network. If this is the case, a dialog is displayed where the user is requested to complete any missing

equipment characteristics. The control module can tell which version is installed, or, if the control module is

installed or not.


Step 7: end flashing


Clicking on x Flashing  to begins the process of exiting the flash session.

Yes: the flash session ends.

No: the flash session does not end.

Depending on the vehicle, end module programs may run here just as they do when exiting Guided Fault Finding.

It is also possible to send a feedback about a flash session. The feedback can also be skipped.

Offboard Diagnostic Information System Service then returns to the start page in the  Flashing mode.
