Code P1615 Buick Description
The P1615 Buick code indicates a loss of Vehicle Theft Deterrent (VTD) serial data communication within the vehicle's system. The VTD system is designed to prevent unauthorized vehicle operation by disabling the engine starting process if the proper key is not used. When this code is triggered, it means that there is a communication issue between the various components of the VTD system, such as the Body Control Module (BCM), Engine Control Module (ECM), and the key itself. This can lead to the vehicle not starting or difficulty in starting, as the VTD system may not recognize the key or authenticate it properly.
