Power and Ground Distribution: Service Precautions

Electronic modules such as instrument clusters, powertrain controls and radios incorporate the latest technology. Some of the components used in these modules are sensitive to static electricity damage at voltage levels far below what the human body can sense. While a person cannot feet or hear the "snap" of a static discharge until the charge level is about 3000 volts, some of the electronic module components can be damaged or weakened by as little as 100 volts.

Use the following safeguards to avoid static electrical damage.

1. Leave the electronic modules in their original packaging until ready to install in vehicles.

2. Avoid touching module connector pins.

3. Avoid laying modules on nonconductive surfaces.

4. As an added safeguard, this kit contains special wrist straps, a 15-inch by 24-inch flexible conductive mat, grounding cords and full instructions.
