Circuit Operation Descriptions - For systems that are not covered in other sections of the Service Manual, Section 8A will contain a circuit operation description (detailed general description) that explains how a system works, what components are involved, and what each circuit does. This description will follow the general description or component location listing.

Option Code References - When optional equipment is shown in Section 8A, it will be identified by the option name followed by the Regular Production Option (RPO) code. The RPO code may be checked against the service parts identification tag on the spare tire well cover to determine whether that equipment should be present.

Export Content - All electrical content, even equipment that is only present on export vehicles, will be shown in Section 8A.

Diagnosis and R&R Reference - Section 8A will reference the appropriate section of the Service Information Manual for diagnosis (if it exists in a section other than 8A) and R&R procedures.

Component View Locators - The component location diagrams, located in 8A-201, will have a car view in the upper left corner highlighting the area of the car shown in the diagram.

Splice Dimensioning - The location of splices will be listed with a measurement to a reference point. For example, the location of splice S119 is listed as "8 inches from the low brake fluid switch".

Harness Retention - Clips or clamps that are used to secure wiring will be shown on the component location diagrams in 8A-201.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
