Code B3055 2014 Chevrolet Silverado Description

The B3055 diagnostic trouble code (DTC) indicates that there is a problem with the transponder modulation or the transponder itself in a 2014 Chevrolet Silverado. The transponder is a small electronic chip embedded in the key that communicates with the vehicle's immobilizer system. When the key is inserted into the ignition, the transponder sends a unique code to the immobilizer system, allowing the engine to start. If the transponder modulation is not functioning properly or if there is no transponder detected, the vehicle's engine may not start or may stall while driving.
