Some customers may comment on, but not limited to, one or more of the following

conditions:

Note: This is a multi-wire bundled harness and depending on which wire is damaged,

can set a variety of DTCs. Not all of the effects or driver notifications listed have been

experienced. However, the different effects and driver notifications may be caused by one

of the wires in the harness being chafed or cut. Components on different lines in the list

below are in different circuits. Due to the cause of the condition, and the positions of the

wires in the harness, it is unlikely that more than one circuit and/or fuse will be affected by

the condition.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these

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 your GM dealer for information on whether your vehicle may benefit from the

information.
