SERVICE INFORMATION
Recently, several dealerships have been asking questions about the possibility of damaging electronic parts during service due to electrostatic discharge (ESD). The need for the Service Technician to wear special static reducing equipment, such as a wrist strap, and the use of a grounding mat when handling electronic parts in the dealerships to prevent the possibility of ESD damage to electronic parts has also been questioned.
The answers to these questions are that if the following rules are followed to reduce the risk of ESD damage, special static protective equipment is not required when handling General Motors parts in the dealership:
When handling an electronic part that has an ESD sensitive sticker, the Service Technician should follow these guidelines to reduce any possible electrostatic charge build-up on the Service Technician's body and the electronic part in the dealership. See Fig 1 .
- DO NOT open package until it is time to install the part.
- Avoid touching electrical terminals of the part.
- Before removing the part from its package, ground the package to a known good ground on the car.
- 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.
