What are the reasons why the vehicle inspection station cannot read OBD data?
1 Answers
The reasons why the vehicle management office cannot read OBD data during vehicle inspection include instrument malfunction, incomplete data, or compatibility issues with the vehicle. OBD testing is a newly added inspection item in recent years, primarily to check whether the vehicle meets standards, including exhaust emissions. OBD reads information such as the vehicle's engine, emission after-treatment devices, and related fault codes. Since OBD testing is a new item, issues with data reading often occur. If the instrument malfunctions or the OBD diagnostic tool does not support the communication protocol used by the vehicle's ECU system, you can try replacing it with a new instrument for testing. If the vehicle management office's system data is incomplete, you can only wait for a data upgrade before retesting. The OBD inspection results directly affect whether the vehicle can be registered and pass the annual inspection. If the OBD test data is abnormal, the vehicle will fail the annual inspection. Driving a vehicle without passing the annual inspection is subject to penalties under the "Road Traffic Safety Law," where traffic police can fine the driver and deduct 3 points, and may also impound the vehicle. If a vehicle fails to undergo annual inspection for three consecutive years, it will be forcibly scrapped.
