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:

Diagnostic Trouble Codes (DTCs) are related to detecting faults (including emissions - related faults), setting fault codes, and triggering the malfunction indicator lamp (MIL). A broken “hard part” is not directly indicated by a DTC; DTCs are more about electronic or system - related faults and their detection, not the physical breakage of a hard part.

Answer:

b. A broken “hard part.”
