Why doesn’t the Autel tool read tire pressure information on my vehicle?

Ensure that your vehicle employs a direct system with sensors to monitor tire pressure. If you are unable to verify if your vehicle uses a direct or indirect system, dismount tire, squeeze or separate its outer tube to see if a sensor is attached to the valve stem.

Indirect systems do not use sensors on the wheels to measure tire pressure, but rather typically use the antilock braking system (ABS) speed sensors to calculate pressure.
