To avoid damaging sensitive electronic parts while handling in the dealership, certain guidelines must be followed.
Figure 1:
When handling an electronic part that has an Electrostatic Discharge (ESD) sensitive sticker (refer to Figure 1), the service technician should follow these guidelines to reduce the possibility of electrostatic charge build up on the service technician's body and the electronic part prior to and during handling the electronic part in the dealership.
1. Do not open package until it is time to install the part.
2. Avoid touching electrical terminals of the part.
3. Before removing the part from its package, ground the package to a known good ground on the car.
4. Always touch a known good ground before handling the part. This should be repeated while handling the part and more frequently after sliding across the seat, sitting down from a standing position, or walking a distance.
