Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostics concept: Add/Remove
When you program a key/remote control, replace a control module or fit an electrical accessory, enter the "Add/Remove" menu. This menu selection combines or separates the component in relation to the car. During separation, important control module data should be entered in the new control module. Keep in mind that any SPS programming must be completed before an "Add". For control modules included in the car's immobilizer function, "Security access" must be acquired first, either with an RS 232 from TIS 2000 when requested by the diagnostic tool or in advance. If security access is acquired in advance, it can be kept during the entire time you are working on the car, even if the diagnostic tool is disengaged from time to time. Key programming and certain activations regarding e.g. the central locking system and electric window lifts are protected and require security access.
