Hello, friends!

Today I am going to show you how to read and write data on an unlocked MC9S12 processor, used in a variety of modules, such as DSM and ISM in FBS4 Mercedes-Benz vehicles. For the procedure I am using the new ZN086 MC9S12 adapter for ABPROG by ABRITES. Using the ZN086 you can read PFlash, DFlash and EEPROM data, save them, and later write it to another module. The whole procedure takes minutes and allows you to effortlessly adapt these modules in the vehicle (clone the donor module onto the new/used one).

It is important to know that the capacitors that need to be removed and the pin that needs lifting, are specific for each processor, and you need to find that information first. Since there are many variations, you will need to do your own research and get to the processor's data sheet.

The ZN086 adapter is soldered onto four points on the PCB (one of which is the lifted pin which is the 42nd pin of the processor, and 14th on the respective side of it) and then connected to the ABPROG. A wiring diagram is available in the upload. The ABPROG is connected to AVDI, and AVDI to your laptop.You will see in the video that I am entering the Upgraded menu of the ABPROG software, but the procedure can also be done with the Classic one. First, you need to read PFlash and EEPROM, save them, and then program them on the replacement module's PCB. That's it.
