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.

If you would like to read more about the on-board diagnostics and how to generate a list of your Diagnostic Trouble Codes, read this article.

Below you will find a table which includes the following information per row:

  1. The Diagnostic Trouble Code (DTC)
  2. The Diagnostic Trouble Code (DTC) Description
  3. The Corvette Module(s) related to the Diagnostic Trouble Code (DTC)
  4. The Corvette System(s) related to the Diagnostic Trouble Code (DTC)
  5. The Corvette years to which the Diagnostic Trouble Code (DTC) applies to

The table includes diagnostic trouble codes for the following systems:

  1. AntiLock Brake (ABS) / Traction Control
  2. Body Control
  3. Cruise Control
  4. Datalink Communications
  5. Doors
  6. Driver Information Center (DIC)
  7. Electronic Suspension Control
  8. Engine Controls
  9. Heater-Ventilation-Air-Conditioning (HVAC)
  10. Horns
  11. Hydraulic Brakes
  12. Instrument Panel, Gauges and Console
  13. Keyless Entry
  14. Lighting
  15. Seats
  16. Stationary Windows
  17. Steering Wheel and Column
  18. Supplemental Inflatable Restraint (SIR)
  19. Theft Deterrent
  20. Tire Pressure Monitor (TPMS)
  21. Transmission (Automatic and Manual)

If any Diagnostic Trouble Code (DTC) has been left out from this list, please comment the five digit code below and a Corvette Salvage Crew Member will add it to the list.
