Handling Electrostatic Discharge (ESD)
NOTICE: When handling electronic parts identified as ESD sensitive, you should observe the following guidelines. These guidelines reduce possible
electrostatic charge build-up from your body and from electronic parts in the Saturn retail facility.
1. Do not open protective package until ready to install the part. When installing always touch the package to a ground before opening.
2. Avoid touching electrical terminals of the part when using a screwdriver or similar tool. Never jump, ground a circuit, or use test equipment probes
on any component or connector unless specified to do so by the service manual when diagnosing an electronic system.
3. Remember solid-state components also can be damaged when bumped, dropped or laid on any metal work benches or components that operate
electrically, such as a radio, TV or oscilloscope.
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 a seat, sitting down from a standing position or walking a distance.
5. When working with the instrument panel cluster and related internal components, the grounding wrist strap of the anti-static mat (SA9502Z) must
be worn and the mat should be properly grounded.
Not all parts that can be damaged by an electrostatic discharge have an ESD label. Components that can be damaged by an electrostatic discharge
are:
^
Instrument panel clusters
^
Powertrain control module (PCM)
^
Chime module
^
Cruise control module
^
Radio
^
Antilock brake system (ABS) control module
^
Electronic ignition (EI) module
^
Sensing and Diagnostic Module (SDM)
6. Remember solid-state components also can be damaged when bumped, dropped or laid on any metal work benches or components that operate
electrically, such as a radio, TV or oscilloscope.
7. Always touch a known good ground before handling the part. This should be repeated while handling the part and more frequently after sliding
across a seat, sitting down from a standing position or walking a distance.
Multimeter Display Reading
Reading Wiring Schematic and Symbols
Each electrical section includes an electrical schematic for the system described in the section. This schematic includes only the fuses, wiring and
components required for the system. This prevents you from being distracted by wiring that is not part of the circuit you are working on.
IMPORTANT: It is important to realize that no attempt is made to represent components and wiring as they physically appear on the vehicle.
For example, a four-foot length of wire is treated no differently in the electrical schematic than a 12-inch piece of wire.
