FAQs
Diagnostic Tools
1. What information should I provide if something goes wrong with the device?
- Your order information
- Serial number of the device
- Car make, model, year
- An incorrect screenshot or video is displayed on the device
2. Why do I get an "Installation failed" error when I download the software?
Android: Long tap the app icon, go to App
Info > Storage > Clear Cache, and try downloading again
iOS: Choose Me > Settings > Clear
Cache and try the download again
3. The TPMS light is lit on the dash of my 2005 vehicle, what should I do?
The tire pressure control module might be faulty.
Use an Autel tool with OBDII-connection capability such as the TS508 or TS608 to detect trouble codes within the TPMS module.
You may need to repair or replace a part within the system such as a transmitter or receiver.
4. My vehicle had a collision. Now my TPMS light stays on. What do I do?
The vehicle may have a damaged TPMS module or non-functioning sensors or both. Use an Autel TPMS tool to check the sensors and the control module. If sensors fail to activate, the sensors need to be replaced. Program Autel’s MX-Sensors to replace sensors. Follow the vehicle manufacturer-specific Relearn procedures displayed on your Autel tool. If the sensors fail to relearn, connect the Autel TPMS to the OBDII port to scan for system faults. You may need to repair or replace a part within the system such as a transmitter or receiver.
5. I cannot complete the sensor relearn.
Please carefully follow the step-by-step instructions displayed under Relearn Procedure on your Autel tool.
6. I performed auto relearn and drove the vehicle, but was unsuccessful in relearning IDs.
Drive the vehicle consistently at the speed of between 25 km/h and 100 km/h (15 mph and 62 mph) throughout the Relearn process. Wait at least 15 minutes before starting a second relearn.
7. The vehicle’s TPMS light displays with the messages “please check tire pressure” and “low-pressure condition”
1. Tire Air Pressure Check:
Ensure the tire air pressure is consistent with the vehicle manufacturer's recommended pressure.
The recommended air pressure can be found on the vehicle's tire placard, which is located on the door jamb of the driver’s side door.
Check the tires for signs of wear and leakage.
It is recommended to inflate the tires when they are cold for the most accurate reading.
2. Tire Inflation Procedure:
Inflate the tires to 10-15 kPa (1.5 to 2 Psi) above the air pressure indicated on the tire placard.
Wait for 15 minutes before deflating the tire back to the recommended pressure.
8. Sensors are properly mounted and have been successfully relearned to the vehicle. The TPMS light displays a few days later indicating “low pressure”. I activated the sensors and the tires read low pressure.
Please double check the valve stems of all sensors to ensure there is no air leak.
9. Clamp-in sensors are properly mounted, but I have trouble dismounting the tires.
The tire will leak if the washer is not securely mounted against the outer rim.
Using the positioning pin, tighten the screw-nut. Do not over tighten.
10. My tool displays a warning message of “duplicated sensor ID”. I cannot complete the relearn procedure and the TPMS malfunction light remains on.
The same sensor might have been activated twice and therefore the tool is displaying duplicate IDs.
When activating sensors, follow the procedure displayed on the screen and activate each sensor at the wheel in the order prompted by the display.
Each Sensor on each wheel must have a unique ID. If two sensors display the same ID, you will need to replace the sensor or re-program the MX-Sensor with a unique ID.
11. The TPMS light displays that the tires on my vehicle were rotated after driving. Then inspecting the tires, l found that the right front tire was low, that is different from the left front tire indicated on the vehicle dashboard
The sensors have to be relearned to the vehicle. After the tire rotation, the registered IDs and their corresponding location do not match what is registered to the vehicle’s ECU.
12. On my Autel TPMS tool, I selected the vehicle model year to activate sensors. Both 315 MHz and 433 MHz frequencies are available. Which option should I choose?
Some vehicle manufacturers use both 315 MHz and 433/434 MHz sensors in the same model year.
For example, Audi used either 315 MHz or 433 MHz frequency sensors on their 2005 and 2007 model year A6 vehicles.
Select one frequency and attempt to activate.
If the sensor fails to activate, choose the other frequency and try to activate the sensor.
