Code B3055 2017 Chevrolet Silverado Description

When a keyless entry transmitter is inserted into the transmitter pocket/slot and the ignition mode switch is pressed, the transponder embedded in the transmitter is energized by the immobilizer antenna exciter coil. The transponder transmits a signal to the immobilizer control module. The immobilizer control module translates this signal to a serial data message which is sent to the Body Control Module (BCM). The BCM then compares this value to a value stored in memory. If the value is correct, the BCM will send the prerelease password via the serial data circuit to the Engine Control Module (ECM). If the learned key code does not match or a transponder value is not received, the BCM will send the start disable password to the ECM. The Diagnostic Trouble Code (DTC) will be set when the BCM is unable to measure the ignition key/transmitter transponder value.
