Diagnose tire pressure fault

Read and clear the fault code of the TPMS system

Program Sensor

This function allows users to program the sensor data to the L AUNCH-sensor and replace faulty sensor with low battery life or one that is not functioning.

There are three options available for programming LAUNCH-sensor: Auto Create, Manual Create and Copy by Activation.
(Note: Do not place the device close to several sensors at the same time, or the diagnostic tool will detect more sensors, which may result in programming failure)

Method 1 - Auto Create

When the original sensor ID cannot be obtained, this function can be used to program the LAUNCH sensor according to the ID randomly created by the test vehicle.

Method 2 - Manual Create

When the original sensor ID cannot be obtained, this function can be used to program the LAUNCH sensor according to the ID randomly created by the test vehicle.

Method 3 - Copy By Activation

By first activating the original sensor data, and then copying the activated sensor data into the LAUNCH sensor. Before using this method, the original sensor data must be activated.

TPMS Relearn

The user can use this function to write the newly programmed sensor ID into the vehicle ECU for sensor identification. Only when the newly programmed sensor ID is different from the original sensor ID stored in the vehicle ECU, the re-learning operation is required.

There are three ways available for Relearn: Static Learning, Self- Learning and Relearn by OBD.

Method 1 - Static Learning

Static learning needs to put the vehicle in "learning mode", and then follow the learning steps prompted on the screen.

Method 2 - Self-Learning

For some vehicles, the learning function can be completed by driving the vehicle self-learning.

Method 3- Relearn by OBD

This function allows the diagnostic tool to write the sensor ID to the TPMS module.

To perform the OBD re-learning function, first use the tire pressure tool to activate all four tire sensors. Then use the diagnostic equipment and its attached diagnostic connector, and follow the on-screen instructions to complete the re-learning operation.

common problem

Q: Why does my wireless tire pressure diagnostic tool keep staying on the startup page?
Answer: It is normal that the wireless tire pressure diagnostic tool always displays the boot page, which means that the tire pressure tool is not currently in the TPMS function mode. If the communication between the tire pressure tool and the diagnostic device is normal, as long as the diagnostic device is executing the TPMS function, the tire pressure tool will switch to the corresponding function page.

Q: Why does my wireless tire pressure diagnostic tool never respond when the diagnostic device performs TPMS operations?
Answer: If this happens, please check carefully:
1. Whether the tire pressure tool is successfully bound to the diagnostic equipment.
2. Check whether the tire pressure tool you are currently using is checked in the "Binded Equipment" list. ·Whether the tire pressure tool is turned on.
3. Whether the tire pressure tool is broken.

Q: Why does my wireless tire pressure diagnostic tool automatically shut down?
Answer: If this happens, please check carefully:
1. Whether the tire pressure tool has been completely discharged.
2. When the device is turned on, if the device is not charged and no operation is performed within 30 minutes, the device will automatically shut down to save power.

Question: The wireless tire pressure diagnostic tool cannot activate one or more sensors.
Answer: If this happens, please check carefully:
·Whether the tire pressure tool is broken.
·Whether the sensor, TPMS module or ECU itself is damaged or has a problem.
·Whether a sensor is installed on the vehicle. Even if there is a metal valve, it does not mean that there is a sensor on the vehicle. ·The tire pressure tool has detected multiple sensors at the same time.
· The tire pressure tool may have a firmware problem, which requires a firmware repair.

Q: What should I do if there is an unknown problem with my wireless tire pressure diagnostic tool?
Answer: When this happens, please repair the tire pressure tool firmware. On the "Tire Pressure" version page, click [Firmware Upgrade] to upgrade the firmware.
