The 1984 Cimarron incorporates a Cruise Control system called Custom Cruise III. To simplify diagnosis of this sytem, a hand held tester has been developed. The service manual describes an alternate procedure which duplicates the action to the tester.
Attached are brochures from two manufacturers of this tester for your consideration.

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.
