Description

B.U.D.S. provides a function that you can use to update module’s software.

Every time B.U.D.S. reads a MPEM document from a vehicle, it gets the identification of the module, then it looks in its update database to see if it can find a matching software update.  If B.U.D.S. finds an update for the module, then it enables the Update... menu and displays the following icon in the lower right corner of the screen:

To update a module's software

When the module identification matches a mandatory update, then the Update command is called automatically.  To update the module, simply follow the instructions provided by B.U.D.S..

If for any reason the internal software of the module is corrupted and B.U.D.S. cannot read its identification, then you will be asked to enter the vehicle serial and model numbers manually.  In the later case, make sure that you enter the exact numbers, otherwise B.U.D.S. could not match the module with its corresponding software update.

B.U.D.S. also allows you to call the Update command manually.  This can be usefull if an update is available for the module but the update is not mandatory or if an update process has been interrupted.  To manually intiate the update process, follow these steps:

From the Module | MPEM menu to update a MPEM.

From the Module | ECM menu to update an ECM.

Notes

Some models may not need to be updated, even if B.U.D.S. shows that an update is available.

Always consult related service bulletins before updating a module's software since you will not be able to go backward.
