# ECM TERMINAL VOLTAGE CORRECTION TO CHASSIS MANUAL

#### VEHICLES AFFECTED: 1987 A SERIES AND N SERIES WITH 2.5 L L4 ENGINES (VIN CODES R AND U)

An error exists on the "ECM Terminal End View" page of the 1987 "A" and "N" series with 2.5L engines (VIN code R and U).

The voltage reading at Pin B9 (Ignition Ref. Hi) should read as follows:

Key "On" = 4.5V Eng. Run = 3.OV

Please make note of this change on the appropriate pages of the "A" and "N" series Shop Manuals.

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.
