I am planning to hack my car to automatically door lock after reaching some speed and unlock as engine is off

I totally understand what you are looking for but unfortunately we do not have that level of detail in the service information to tell you which variant you would need to alter. In order to do this, you would need an engineering tool in order to be able to rewrite the module software but again, this is not something that an OEM allows to happen as they only allow dealers to update software to their latest versions that they have released.

I understand that there are tools out there that are capable of rewriting this software to alter how a vehicle operates. However, due to it not being an approved practice, the OEM doesn't provide the variant string and definition to know what each means to know what to alter.

Sorry we cannot assist with this detail. Thanks
