Pages 8A- 86-1 and 8A- 86-3 contain incorrect wiring harness connector information for the Driver Information System (DIS) (RPO U51). These pages have been corrected and are reproduced as part of this bulletin. Please mark references to this bulletin on the above pages in your 1989 Cutlass Ciera and Cutlass Cruiser Service Manual.
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.
