Question

which feature allows sensor data readings to be accessed with a scan tool?

a. the on - board diagnostics (obd) window
b. the diagnostic trouble code (dtc) chart
c. the datastream
d. the sensor page

Explanation:

• On - board diagnostics (OBD) window: This is not a standard term for accessing sensor data readings. OBD is a system for vehicle diagnostics but not specifically a "window" for sensor data access.
• Diagnostic trouble code (DTC) chart: A DTC chart is used to interpret diagnostic trouble codes, not to access real - time sensor data readings.
• Datastream: In vehicle systems (which fall under the engineering subfield of Natural Science), the datastream is the set of real - time data from sensors that can be accessed using a scan tool.
• Sensor page: This is not a standard industry - recognized term for accessing sensor data in the context of vehicle diagnostics and scan tool usage.

Answer:

C. The datastream
