# COMPUTER COMMAND CONTROL DIAGNOSTIC CHARTS

#### Vehicles Affected: 1982 Buicks with C-3

The attached charts for diagnosing trouble codes 24 and 55 supersede the charts in the 1982 Buick Chassis Service Manual (Pages 6E1-37 and 6E1-46).

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.
