It will be necessary to reprogram the PCM for speedometer accuracy. Contact Techline (1-800-828-6860 English or 1-800-503-3222 French) to obtain a VCI number. Then refer to the table below for the appropriate calibration part number based on the model year and axle ratio.
Calibration Information Documentation
Make a copy of the "Accessory Wheel and Tire Information Form" included in this bulletin.
Provide all information required on the form.
Make a copy of the completed form for the customer to keep in the vehicle along with their Owner's Manual.
File the original completed form in the Dealership's Vehicle Service History folder.
Important: Because this is not a warranty repair, dealers will incur a charge to obtain a VCI number.
All GM Accessories sold and permanently installed on a GM vehicle PRIOR to new vehicle delivery will be covered under the provisions of the New Vehicle Limited Warranty.
In the event GM Accessories are installed AFTER new vehicle delivery, or are replaced under the new vehicle warranty, they will be covered (parts and labor) for the balance of the vehicle warranty, but in no event less than 12 months/12,000 miles (in Canada, 12 months/20,000 kilometers). This coverage is only effective for GM Accessories permanently installed by a GM dealer or a GM approved ADI (Accessory Distributor / Installer).
GM Accessories sold over-the-counter, or those not requiring installation, will continue to receive the standard GM Dealer Parts Warranty of 12 months from the date of purchase (parts only).
