C5 Corvette Diagnostic Trouble Codes (DTCs) & Descriptions

What is a Diagnostic Trouble Code (DTC)?

A Diagnostic Trouble Code (DTC) is a systematic coding structure used by a Corvette to signal that an issue has occurred. Each DTC consists of one letter and four digits, such as B0605, and corresponds to a specific error/fault. When a component or system is not operating within acceptable limits, the Corvette will activate the appropriate DTC and store it within the Body Control Module (BCM). This code can be retrieved by the driver at any time to identify and fix any issue with the Corvette.
