Handling control modules

Handling control modules


All control modules are more or less sensitive to static electricity and if handled incorrectly could be damaged so seriously that they no longer work properly. It is therefore important to follow the rules below in all situations where the control module has to be removed or replaced for any reason.


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

• Never touch the connector pins and never place the control module in such a way that the pins come into contact with foreign bodies.

• Before unpacking a new control module, ground the packaging to the car body. Open the packaging as shortly as possible before installing the control module.

• When carrying out work involving a control module it is important to ground yourself at regular intervals. This is particularly important if you have been sitting in the car, if you have changed position or moved round the car. It is even more important in climatic conditions with very dry air (such as during the winter in cold-climate markets).

• Avoid wearing clothes made of synthetic materials (man-made fibres).

• Avoid shoes with insulating rubber soles.

• Always handle any control module suspected of being faulty in the same way as a control module in perfect working order. This will considerably increase your likelihood of finding the cause of the fault.
