On page 8A-44-5 of the 1989 Oldsmobile Toronado Service Information Manual the component location for the Anti-Lock Brake System diode is listed incorrectly.
The correct location is "in the trunk, on the left wheelhouse, taped to the Electronic Brake Control Module (EBCM) harness". The illustrations which are referenced, Figures 201-7B and 201-8D, also show incorrect locations.
Please note these corrections in your books.
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.
