Good afternoon,

The VIN has to be changed as well as the mileage from the old cluster.

Do you have access to Tech Authority for Chrysler to program the module? I do not see that option on your scan tool.

You get a daily pass or weekly pass. Then you need to be sure your scan tool can program the ECM correctly.

The ideal scan tool is the DRB 2.

Maxi AP 200 have the option to replace PCM and write VIN on the PCM. I have seen videos and try it but I didn't have pin code for car. How can I get pin code by VIN?

You can get that from the dealer. They will have access to that information.

No, there is not. You need to get the information from the dealer service. They can look it up for you and get you the correct one.

The one you have may have been updated and you want the most current version for the ECM.

You mean the ABS cab or control unit. Like it says, some of the models built put it in the way and it must be removed to access the ECM.

I attached the procedure below for you.

You mean trying to start it without programming the ECM? If you do, no, it will not work. The ECM will not allow spark and fuel until the ECM is on board with the rest of the modules.
