Handling Control Modules
All control modules are more or less sensitive to static electricity and, if handled carelessly or incorrectly, may be damaged so seriously that they
no longer work properly. It is therefore important to ensure that the following rules are observed at all times when a control module is removed or
replaced for any reason.
-
Avoid unplugging or removing a control module unless absolutely necessary.
-
Never touch the connector pins and never place the control module in such a way that the connector pins may come into contact with foreign
objects.
-
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.
-
Avoid wearing clothes made of synthetic (man-made) fibres.
-
When handling or working on control modules it is important to ground yourself from time to time. This is particularly important when you
have been sitting in the car, when changing your position, or when moving round the car. It is even more important in a climate with extremely
dry air (e. g. during the winter in cold markets).
-
Furthermore, always handle control module which are suspected of being defective in the same manner. This will greatly improve the chances
of determining the cause of the fault.
