2007-08 Chevrolet Silverado, Express; GMC Sierra, Savana: Use data version 5.5 for 2008 as of 05/12/08 or later, available on TIS 2 WEB; and on TIS
DVD version 6.0 / 2008 or later, mailed to dealers beginning 06/04/08.
If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
Service Procedure
Program Engine Control Module
Important:
Verify that the 12 volt battery has a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Only
use approved Midtronics 165-PCS charger or equivalent to maintain proper battery voltage during programming.

Refer to Service Programming System (SPS) in SI for programming procedures.

Program the ECM with the latest calibration. This calibration, or any that follow, is designed to address VTD concerns. As always, make sure your
Tech 2(R) is updated with the latest software version.

Select the J2534 MDI and Reprogram the ECU from the Select Diagnostic Tool and Programming Process screen. The J2534 MDI will reprogram
the modules in less time than the Tech 2(R) scan tool.

Courtesy Transportation - For US and Canada
The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered
by the New Vehicle Limited Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period
and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that
shuttle service or some other form of courtesy transportation is available and will be provided at no charge. GM dealers should refer to the General
Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
