Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electrostatic Discharge (ESD) Sensitive Devices
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build up on the body and inadvertent discharge into the component. If it is not known whether the component is ESD sensitive, assume that it is.
Perform the following procedure when handling ESD sensitive components:
- Always touch a known good ground before handling the component. This should be repeated while handling the component and more frequently after sliding across a seat, sitting down from a standing position, or walking a distance.
- Avoid touching electrical terminals of the component, unless instructed to do so by a written procedure.
- When using a voltmeter, be sure to connect the ground lead first.
- Do not remove the component from its protective packing until it is time to install the component.
- Before removing the component from its package, ground the package to a known good ground on the vehicle.
