Radio Reprogramming Using TECHLINE/Service Programming System (SPS) - Ensuring Correct Vehicle Selection (PI1266)
Reference number: PI1266
RADIO REPROGRAMMING USING TECHLINE/SERVICE PROGRAMMING SYSTEM (SPS) - ENSURING CORRECT VEHICLE SELECTION
TECHNICAL SERVICE BULLETIN
| Affected Model(s): | 2015 and Prior GM Passenger Cars and Trucks |
CONDITION/CONCERN
A technician may find that when manually building a vehicle in SPS, more than one vehicle is shown in the list of available vehicles for programming.
RECOMMENDATION/INSTRUCTIONS
To ensure proper vehicle selection, it is recommended to use the vehicle VIN within SPS. This way the system selects the correct vehicle information, including all applicable option codes, and loads the correct software for that particular vehicle.
When a country (i.e. China) is listed in the Car Line, this is to identify its country of sale, not its point of origin.
