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.
When the control module is to be replaced
- Place the old control module in the return packaging without touching its pins.
- Keep the new control module in its packaging as long as possible.
Before removing a control module, Tech 2 must be used to separate the control module from the car. From the "All" menu, select the control module under "And/Remove". Then select "Remove" and follow the instructions. The ignition key must be in the ON position. TIS 2000 may be required. Once the control module has been separated from the car, turned the ignition key to the OFF position. The control module can then be removed. Carry out the "Remove" action with Tech2 even if the control module cannot be contacted or is completely missing because data in other control modules must be changed.
The action involves the following
Security codes will be reset, bus lists updated, data in other control modules updated and data that may have to be written into a new control module read and displayed.
When the component is to be replaced
- Place the component in the return packaging without touching its pins.
- Keep the new component in its packaging for as long as possible.

- When detaching connectors with locks, it is essential that the lock is released before the connector is detached. Ensure the connector locks properly when connecting. Example of some different connector types used in the car: Pull out the slide to unlock the connector. After attaching the connector lock it by pressing in the slide. NOTE: Using a small screwdriver will help to unlock the connector. Press in the lock tab to unlock the connector. Make sure the connector is locked properly when connecting. Pull out the slide to unlock the connector. After attaching the connector lock it by pressing in the slide. Press in the brace catch and push forward the brace. Push back the brace to lock the connector after connecting. NOTE: Make sure the brace is locked in the right position to ensure good contact between connectors. Lift up the lock tab to unlock the connector. Make sure the connector is locked properly when connecting. Press in the connector lock tab to release the brace. Release the connector slide while pushing the brace forward. NOTE: The connector may be damaged if too much force is used to push forward the brace without first releasing the slide. Push back the brace to lock the connector after connecting.
- Ground yourself by touching the car body/engine before removing or fitting any of the connectors on the car's control modules.
- Never pull the wiring harness when removing a connector.
- Never touch the pins on the control module with your hands or clothes. IMPORTANT: Incorrect handing or the use of the wrong tool can damage the sleeves in the connector. Use a test cable (part no. 86 12 731) of the correct size to avoid damaging the sleeves in the connector.
- When testing only probe tips intended for the purpose are to be used to avoid damaging the contacts. Use a test cable (part no. 86 12 731) of the right size.
- Connectors may only be repaired when using specified special tools and spare parts.
- The following connectors must not be repaired: Screened wires/coaxial cables (e.g. ESP sensor cable) Airbag system and pyrotechnical seat-belt tensioner system High tension cable (e.g. ignition system, xenon lamp).

- Check for any contact problems in connections.
- Check contacts, connectors and crimp connections with respect to oxidation, loose pins and pin clamping force. IMPORTANT: Incorrect handing or the use of the wrong tool can damage the sleeves in the connector. Use a test cable (part no. 86 12 731) of the correct size to avoid damaging the sleeves in the connector.
- To check the connector clamping force, use a test cable with the right pin size (from kit 86 12 731). NOTE: Using a test cable that is too big will damage connector sleeves. Insert the test cable pin into the connector pin to feel the clamping force of the pins in question. Poor clamping force of the connector pins can cause bad contact. Also check that the engagement height of the pin is the same as the other pins in the connector. An engagement height that is too low could be an indication of a loose pin in the connector, which could cause bad contact.
- Check wires and connections for open circuits.
- Check wiring harness, connectors and ground connections.
