Remote Vehicle Speed Limiting

Remote Vehicle Speed Limiting Description and Operation

Certain vehicles equipped with OnStar(R) now have an additional feature that allows for remote limiting of the vehicle's speed. This OnStar(R) feature is called Stolen Vehicle Slow-Down and is now part of the OnStar(R) Stolen Vehicle Assistance service. This feature, when used in conjunction with local law enforcement and strict guidelines at the OnStar(R) Call Center, will slow the vehicle by interacting with the engine control system.

When the engine control system receives a valid request from the OnStar(R) telematics communications interface module, it will enter into a reduced engine power/vehicle speed limiting mode, which will decelerate the vehicle. Once the request is active the engine control module begins reducing engine torque to match requested vehicle speed and a REDUCED ENGINE POWER indication is displayed. No DTCs will be set during this process.
