Updated software has been released to address this condition. If you encounter a vehicle
with the above condition, reprogram the ECM with the latest available software.
Service Procedure
Parts Information
1. Ignition ON.
2. Perform the Diagnostic System Check - Vehicle.

are set.

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.
