ESD (Electrostatic Discharge)

The remote keyless entry (RKE/Security System) is a subsystem of the body control module (BCM). This system has components which are sensitive to electrostatic discharge. ESD can damage many solid state components. Not all components that are susceptible to damage from ESD are labeled with the ESD precautionary symbol. Exercise caution when handling all solid state electrical components.

Avoid damaging solid state components by taking the following precautions:

• Discharge personal electricity by touching a metal ground point after sliding across the vehicle seat, sitting, rising or walking.
• Do not touch the exposed electrical terminals on a component with your fingertip or tool. The connector that you are checking may be tied into a circuit that is susceptible to damage by ESD.
• Do not allow a screwdriver or similar tool to contact exposed terminals when disconnecting a connector.
• Do not remove the protective packaging of the solid state component until you are ready to install the solid state component.
• Unless specified in a particular diagnostic procedure, avoid jumping components or connectors, grounding components or connectors or using test equipment probes on components or connectors.
• When a diagnosis requires the use of test equipment probes, connect the ground lead first.
• Touch the solid state component's package to a ground before opening the package.
• Do not lay the solid state component on a metal workbench or on top of an electrically operating appliance or piece of equipment.
• Do not drop the solid state component.
