2015 and Prior GM Passenger Cars and Trucks

This bulletin has been revised to update the A/C Service Equipment and Service Department
Computers information. Please discard Corporate Bulletin Number 05-00-89-029B.

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.

Brake Equipment
GM Equipment Requirements*
• Capable of producing rotor surfaces with less than 0.051 mm (0.002 in) assembled runout.
• Capable of producing rotor surfaces with less than 0.025 mm (0.001 in) lateral runout (as measured on the lathe
arbor – bench lathe).
• Capable of producing flat surfaces (no dishing).
• Capable of producing rotor surfaces with less than 0.0076 mm (0.0003 in) thickness variation.
• Use secondary non-directional surface finishing tools.
• Capable of producing surface finish of 40 Ra (Roughness Average) or less (after secondary finish operation).
• All adapters, vibration dampeners, hardware and cutting inserts in good condition.
• Measure and document brake rotor original and refinished thickness.
• Use Essential Cleaning tools J-42450A and J-41013 to clean rotor hat and hub surfaces before rotor
machining.
• Measure all brake drums prior to installation to ensure drum is not beyond maximum dimensions.
• Measure all brake rotors with a dial indicator and index that rotor on the hub to correct excessive lateral runout.
• Use the proper Brake-Align shims to correct lateral runout when necessary.
• Operators properly trained and ASE certified (U.S. only) in brake service.
*Equipment meeting the requirements above supports procedures specified in the latest version of Service Bulletin
Number 00-05-22-002 – Brake Service and Procedures. Essential tool CH-47661 – Pro-Cut PFM 9.2
Auto-Compensating On-Car brake lathe meets the requirements above and supports the latest versions of Service
Bulletin Numbers 00-05-22-002 – Brake Service and Procedures and 03-05-23-005 – On-Car Brake Lathe for
2005-2013 Colorado and Canyon trucks.

Solutions and GMIT Standards. In Canada, refer to the GM Canada Dealer Infrastructure Guidelines in the Service
Library of GlobalConnect.
Business Grade PC Specifications
PCs that are not business grade are considered "non-supported hardware.” Unlike a home grade PC, a business or
commercial PC is specifically configured for use in a business 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-business
grade hardware.
Important: Non Pentium processors such as Celeron®, Cyrix and AMD are NOT compatible with Techline software.
