Code P162B Buick Description
The P162B Buick code indicates that the remote vehicle speed limiting signal message counter is incorrect. In modern vehicles, remote vehicle speed limiting systems are designed to restrict the maximum speed at which a vehicle can travel. This is often used in fleet vehicles or by parents to limit the speed of a car driven by a teenager. The signal message counter tracks the number of times the speed limiting signal has been sent and received by the vehicle's control module. When the counter is incorrect, it means that there is a discrepancy between the expected number of signals and the actual number received.
