Before Control Module Replacement

Measures Before Removing The Control Module






The control module is sensitive for electrostatic discharges. In order not to damage the internal components in the control module replacement must be performed with care according to the following:
- Never touch the pins on a control module with your hands or clothes.
- Ground yourself by touching the cars body/motor. Dismantle the connector on the car's control module.
- Ground yourself by touching the cars body/motor. Connect the connector on the car's control module.

When changing a control module
- Place the replaced control module in the return packaging without touching its pins.
- Keep the new control module in its packaging as long as possible.

Before a control module is dismantled Tech 2 should be used to separate the control module from the car. Access the menu "All" and select the control module under "Add / Remove". Now select "Remove" and follow the instructions. The ignition key must be in the ON position. You may need to use TIS 2000. When the control module is separated from the car the ignition key should be turned to the OFF position. The control module can then be dismantled. Perform a "Remove" using Tech 2 even if the control module can not be contacted or is actually missing on the car as data needs to be changed in other control modules.

This happens with regard to data:
Security codes are reset, bus lists are updated, data in other control modules is updated and data that may be written back in a new control module is read and shown.
