Handling control modules

Handling control modules


All control modules are sensitive to static electricity and can, if they are handled incorrectly, be damaged so seriously that they cease to function correctly. For this reason, it is important that the following rules are followed at all times when the control module must be removed or replaced for any reason.


• Avoid undoing or removing the control module if it is not absolutely necessary.

• Never touch the contact pins and never place the control module in such a way that the pins may come into contact with any objects.

• Before unpacking a new control module, ground the packing to the car body. Open the packing as short a time as possible before fitting.

• Avoid working in clothes of synthetic materials.

• When working with the control module, it is important that you regularly ground yourself to the car. This is especially important when you have been sitting in the car, when you have changed position or moved around the car and even more important when working under climate conditions with very dry air (for example during the winter in cold markets).

• Always handle control modules that are suspected of being faulty in the same way. This will considerably increase the chances of finding the cause of the fault.
