Handling Electrostatic Discharge (ESD) Sensitive Parts


Electronic modules are very sensitive to Electrostatic Static Discharge (ESD). If the modules are exposed to these charges, they may be damaged. While most vehicles display a label informing you that their electronic components may be damaged by ESD, some do not have labels, but they may be damaged also. To avoid possible damage to any of these components, follow the steps outlined below in Handling Electrostatic Discharge (ESD) Sensitive Parts.

  1. Body movement produces an electrostatic charge. To discharge personal static electricity, touch a ground point (metal) on the vehicle. This should be performed any time you:

    Slide across the vehicle seat
    Sit down or get up
    Do any walking

  3. Do not touch any exposed terminals on components or connectors with your fingers or any tools.
  5. Never use jumper wires, ground a terminal on a component, use test equipment on any component or terminal unless instructed to in a diagnostic or testing procedure. When using test equipment, always connect the ground lead first.
