CAMPAIGN: IDLE STOP SOLENOID JUMPER WIRE OMITTED

GENERAL MOTORS HAS DETERMINED THAT SOME 1981 CHEVROLET CITATIONS EQUIPPED WITH A V6 ENGINE, AUTOMATIC TRANSMISSION AND AIR CONDITIONING WERE ASSEMBLED, WITHOUT THE REQUIRED IDLE STOP JUMPER WIRE ASSEMBLY (INCLUDING DIODE). WITHOUT A DIODE AND WHEN THE SOLENOID IS DE-ENGERIZED, A VOLTAGE TRANSIENT IS GENERATED IN THE ELECTRICAL SYSTEM SUFFICIENT TO "RESET" THE ECM (ENGINE COMPUTER COMMAND MODULE). THE RESET ERRONEOUSLY ACTIVATES THE "CHECK ENGINE" LAMP WHICH IS A MISLEADING INDICATION OF SYSTEM FUNCTIONING.

VEHICLES INVOLVED

INVOLVED ARE CERTAIN 1981 CHEVROLET CITATION MODELS EQUIPPED WITH A V6 ENGINE, AUTOMATIC TRANSMISSION AND AIR CONDITIONING ASSEMBLED AT THE FOLLOWING ASSEMBLY PLANTS WITHIN THE FOLLOWING VEHICLE PARAMETERS:

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.
