Required Tools

Activation Tool (AKA trigger tool) such as Ateq VT55 or VT30





      1.   Review all data in your owner’s manual pertaining to your TPMS system.

      2.   Verify that your vehicle is listed in the application coverage listing of the trigger tool. 

      3.   Perform trigger tool software update.

      4.   Verify that the OEM trigger tool is working (check battery if needed). 


Note: This step should be performed only by a tire technician who has been properly trained in the operation and installation of TPMS systems.

      1.   Install Sensors - Properly install tire pressure sensors. 

      2.   Tire Pressure - Confirm all tires are inflated to the pressure indicated on tire placard. (the tire placard is located on the door jam of your vehicle)


This is a sample tire pressure placard.

Not for this specific vehicle.

      3.   Eliminate Interference - To ensure the control unit memorizes the correct sensor ID, the vehicle with the new sensor must be at least 3 m. (10 ft.) from any other TPMS pressure sensor not installed on that vehicle.


Do not press the reset button (the reset button is only used when rotating tires).


Note: Follow the instructions provided by the manufacturer of the scan tool to select the proper make/model/year of the vehicle.

      1.   Place the trigger tool against the tire sidewall close to the rim at the valve stem location, then press and release the Activate button on the tool.  The tool will store the sensor data and advance the menu to the next tire.

      2.   Repeat the reset procedure in step 5 for each of the remaining 3 tires in the following clockwise order:

a.    Right front tire (Front passenger’s side)

b.    Right rear tire (Rear passenger’s side)

c.    Left rear tire (Rear driver’s side)

     3.   Connect the scan tool to the vehicles OBD port.

     4.   Place the key in the ignition and turn it to the on position with the engine off.

      5. Follow the tool manufacturer’s instructions for transmitting data to the ECU.  When the stored sensor data has been successfully transferred from the tool to the ECU, the relearn procedure is complete.  Disconnect the tool from the OBD port.
