The functional OBDII test is required on all 1996 and newer vehicles with a GVWR of what weight or less?

• A. 9,000 lbs
• B. 7,500 lbs
• C. 8,000 lbs
• D. 8,700 lbs

Answer: (D)

The test checks which vehicles must undergo a functional OBD II evaluation based on how much they weigh. For vehicles from 1996 and newer, the functional OBD II test is required if the GVWR is eight thousand seven hundred pounds or less. This threshold matters because it separates lighter, commonly used passenger cars and light trucks from heavier vehicles that use different testing methods. The functional OBD II test focuses on the vehicle’s on-board diagnostic system—verifying that the computer and its monitors are able to detect and report emissions-related faults properly, rather than performing the full emissions test. So, among the options, the weight limit that matches this testing rule is the one indicating eight thousand seven hundred pounds.
