This bulletin is being revised to include an updated Code 26 Chart for all 1992 "L" Carlines equipped with the 2.3L (VIN A) engine. The Chart has been enhanced to incorporate improved diagnostics with the aid of a Tech 1 Scan tool.
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.
