# CCC CODE 23 CLEARING STORED CODES

ON ALL 1981 CARS WITH COMPUTER COMMAND CONTROL, CODE 23 CAN BE ENTERED INTO THE MEMORY BY DISCONNECTING THE M/C SOLENOID AND TURNING THE IGNITION SWITCH ON WITHOUT STARTING THE ENGINE. IT MAY BE POSSIBLE TO SET OTHER CODES WITHOUT STARTING THE ENGINE, PROVIDING A MALFUNCTION EXISTS AT THE TIME AND THE CODE DOES NOT REQUIRE A PREDETERMINED TIME BEFORE SHOWING ITSELF.

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.
