Question

a dtc indicates that a vehicle has experienced all of these except:

a. an emissions related fault.

b. a broken “hard part.”

c. a set fault “code.”

d. an illuminated malfunction indicator lamp (mil).

Explanation:

A Diagnostic Trouble Code (DTC) is related to emissions - related faults, sets a fault code when an issue is detected, and can cause the Malfunction Indicator Lamp (MIL) to illuminate. It does not directly indicate a broken "hard part" as its primary function is to signal system - level or sensor - related faults rather than physical component breakage.

Answer:

B. A broken "hard part."
