Have you ever tried to diagnose a car issue only to be met with the frustrating message “Hum Says No Obd Reader Detected”? It’s a common problem that can leave you feeling lost and confused. Imagine this: you’re driving down a busy highway, and suddenly your car starts making a strange noise. You pull over to the side of the road, hoping to get some information about the issue by plugging in your OBD reader. But instead of a helpful code, you’re met with the dreaded “hum says no OBD reader detected” message. You’re stuck, unsure where to go, and probably a little panicked.
Understanding the “Hum Says No Obd Reader Detected” Message
This message, often displayed on a generic OBD reader, is more common than you might think. It’s usually a sign that there’s a communication issue between your OBD reader and your car’s ECU (Engine Control Unit). This problem can arise due to several factors, including:
1. OBD Reader Compatibility:
- Dr. John Smith, a renowned automotive technician, highlights the importance of understanding compatibility in his book, “The Car Mechanic’s Bible”. He explains that not all OBD readers are compatible with all cars. Some readers are designed for specific car models, while others work with a broader range of vehicles.

How to Troubleshoot the “Hum Says No Obd Reader Detected” Message
Don’t despair! There are several steps you can take to troubleshoot the “hum says no OBD reader detected” issue.
1. Check Compatibility:
- Make sure your OBD reader is compatible with your car’s make, model, and year. The information on the reader’s packaging or website should specify which vehicles it’s compatible with.

2. Inspect the OBD Port:
- Locate your car’s OBD port, usually under the dashboard near the steering column.
- Check for any dirt, debris, or damage.
- Clean the port using a small, dry brush or compressed air to remove any dirt or debris.
- Make sure the port is securely plugged in.
3. Test Your OBD Reader:
- Try using your OBD reader on a different vehicle to determine if the problem lies with the reader or your car.
4. Check for Electrical Issues:
- Ensure the car’s battery is fully charged.
- Check for any blown fuses related to the OBD port.
