Which list best describes the kinds of DTC statuses viewable through Toyota TechStream?

• A. Current
• B. Pending
• C. All of the Above
• D. History

Answer: (C)

TechStream shows DTCs in different life-cycle states, and understanding these helps you interpret what’s happening with the vehicle. A current DTC is one that is actively active and typically lights the MIL, indicating an ongoing fault. A pending DTC has been detected but hasn’t yet been confirmed as a fault—if the condition reoccurs over a set number of drive cycles, it may become current. A history DTC is a fault that occurred previously and is stored for reference even if it’s not active right now. Because TechStream can display all three kinds, the best description is the one that includes Current, Pending, and History. This triad is especially useful for spotting intermittent issues or tracking faults that have occurred in the past.
