Diagnostic Concept: Add/Remove

When you program a key/remote control, change a control module or fit an electrical accessory, you need to access a new menu called "Add/Remove". The menu option marries and separates components in relation to the car. During "divorcing", critical data can be copied from a control module which is later loaded into the new control module. Remember that any SPS programming should be done before an "Add" operation. You must also retrieve "Security Access" for control modules included in the car's immobilization function. This is retrieved via RS 232 from TIS 2000 when the diagnostic tool requests it. You can also retrieve security access in advance and then kept it for the entire time you are working on the car in question, even if you disconnect the diagnostic tool now and again. Key programming and some activations that concern the central locking system and electric window lifts, for example, are also protected and require security access.
