Critical Equipment
As established in the Dealer Sales and Service
Agreement, in addition to required essential service
tools, the dealer agrees to provide such other tools and
equipment as reasonably necessary to fulfill its
responsibilities to properly diagnose and service
General Motors vehicles. This bulletin is intended to
provide General Motors dealerships with requirements
and recommendations for service equipment that has
been identified as critical equipment necessary to
properly repair and maintain General Motors vehicles.
The proper maintenance and/or replacement of existing
equipment with General Motors approved equipment
(available through GM Dealer Equipment) will ensure
proper serviceability and contribute to improved
customer satisfaction and dealer profitability.

Equipment Maintenance
Regular maintenance and calibration is essential to
assure the use of equipment results in high quality and
satisfactory repairs. Most manufacturers recommend
weekly or monthly cleaning and inspection of
equipment with repair or replacement of worn or
damaged parts as needed. Annual or semi-annual
calibration of equipment is also recommended,
depending on frequency of use. The manufacturer of
your equipment will have specific recommendations
and, in many cases, can provide inspection and
calibration services.

Enterprise Grade PC Specifications
PCs that are not enterprise grade are considered
"non-supported hardware.” Unlike a home grade PC,
an enterprise or commercial PC is specifically
configured for use in a enterprise network
environment. PCs in this class have components
designed and supported for use in a network
environment. Additionally, they have greater life cycle
stability due to "designed-in" serviceability. Techline
applications will not function properly on typical
non-enterprise grade hardware.
Important: ALL Processors below the Intel Core i
series plus AMD, Celeron, Pentium, and Atom
processors are NOT compatible with Techline software.

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.
