<\/p>\n
<\/p>\n Certain accessories may not require a calibration update based on vehicle build or trim level. Refer to Service Information installation instructions for specific vehicle requirements.<\/p>\n TIP:<\/strong> Limited Production Option (LPO) accessories are ordered with the vehicle at the time of purchase. Some LPO accessories should not be installed or sold as an Accessory Catalog Offering (ACO), or over-the-counter accessory, as the required calibration may not be available for ACO applications. If a calibration is installed on an incorrect vehicle, several DTCs may set.<\/p>\n <\/p>\n Programming Required Calibrations <\/strong><\/p>\n GM Accessories that require updated calibrations must have the calibrations installed to ensure proper operation of the new accessory components as well as other related vehicle systems, whether it\u2019s an air intake system that includes an ECM update, a front grill package that involves front camera operation, or larger wheels and tires that impact the operation of Advanced Driver Assistance Systems on the vehicle. Calibration updates that are not performed following the installation of an accessory may not only limit system performance, but may also leave the vehicle non-compliant with certain government standards\/regulations.<\/p>\n Prior to programming, contact the TCSC to have the appropriate calibration applied to the VIN. The VIN and Authorization Code (included in the accessory packaging) must be provided to the TCSC to obtain the accessory calibration.<\/p>\n TIP:<\/strong> If programming is attempted before contacting TCSC when installing accessories that require an updated calibration, the Service Programming System (SPS) will not deliver the correct accessory calibration to the vehicle. SPS may display a message advising users that they are attempting to program with the \u201csame calibration” \u2014 a warning that the vehicle has not received the required accessory calibration. Do not use any \u201csame calibration,\u201d or lack thereof, messaging as an indication that an accessory calibration update is not required.<\/p>\n <\/p>\n Always Review the Service Information<\/strong><\/p>\n Before installing any GM Accessory, it\u2019s critical to review the installation instructions in the appropriate Service Information. Installation sheets for GM Accessories can be found in the Accessories Manuals in the Service Information. (Fig. 17) By checking the installation procedures, even on commonly installed accessories, any updated information or improvements \u2013 including required calibrations \u2013 that have been implemented can be reviewed before installation begins, ensuring that the latest information is followed for an efficient, accurate and quality installation.<\/p>\n <\/p>\n <\/p>\n Installation Questions<\/strong><\/p>\n The following sources are available to help dealerships with the installation and operation of GM Accessories.<\/p>\n Techline Customer Support Center<\/strong> \u2013 Programming concerns with GM Accessories<\/p>\n Technical Assistance Center<\/strong> \u2013 Installation or help with diagnosing problems related to the installation<\/p>\n Partech<\/strong> \u2013 Accessory installation sheets, missing kit components, quality issues, and vehicle compatibility questions.
