Antitheft and Alarm Systems: Service Precautions

Handling Electronic Control Modules (Part 1 Of 2):

All control modules are more or less sensitive to static electricity and can, if they are handled incorrectly, be so seriously damaged as to be rendered unserviceable. It is therefore important that the following rules are always followed when a control module is to be removed or changed for whatever 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 so that the connector pins may come into contact with anything else.
- Before unpacking a new control module, ground the packaging to the car body and open the packaging as short a time as possible before fitting.
- When working with control modules, it is important to regularly ground yourself. This is especially important when you have been sitting in the car, when you have changed position or have move around the car and especially in climatic conditions with very dry air (e.g. in the winter in cold markets).
- Avoid wearing clothes of synthetic materials.
- Avoid shoes with insulating rubber soles.

Handling Electronic Control Modules (Part 2 Of 2):

- Always handle control modules suspected of being defective in the same way. This significantly increases the possibility of localizing the cause of the fault.
