Manual learning function introduction
1. Manual learning provides a convenient way for the driver to update the tire
pressure sensor ID. The driver can complete the learning through the sub-menu of
"self-learning sensor" of the instrument without the help of after-sales diagnosis instru-
ment. This feature is often used in two situations:
A. When the tire is replaced and a new sensor is replaced, it is necessary to
relearn the sensor ID of the position;
B. The tires of two positions on the same vehicle are switched, and no new sen-
sor is replaced;
This function selects the sub-menu of "self-learning sensor" by the driver, selects
the tire position that needs to be learned, and presses the confirm button to trigger
learning. Next, the driver can trigger the sensor in 5 minutes. The driver can trigger the
sensor in two ways. The first is triggered by the use of hand-held low-frequency tools
provided by the 4S store, and the second is triggered by the opening of the valve
valve core to deflate the tire. There will be continuous text reminders on the instru-
ment interface of learning progress, success and failure, and the driver can return to
the cockpit after the sensor is triggered
Get feedback on learning outcomes. After successful learning, the newly
replaced sensor ID will be recorded to the corresponding location of the TPMS control
unit assembly; If the learning fails, please check the reason for the failure according to
the corresponding text reminder, then exit the sub-menu of "self-learning sensor" and
re-enter and re-learn.
2. Safety conditions for manual learning before manual learning, drivers must
check whether the vehicle meets the following conditions:
A. The vehicle is at rest (the speed is 0 and the engine speed is 0);
B. The ignition key is in the ON gear (the engine is not started);
C. The sub-menu of "tire pressure monitoring system" works normally;
3. Operating instructions
Replace the new sensor before left
A. Confirm that the vehicle meets the safety conditions for manual learning;
B. Enter the sub-menu of "self-learning sensor" of the instrument, select the left
front wheel and click OK to confirm;
C. If the menu of the interface shows "in learning, please activate the sensor".
Please get off the bus within 5 minutes and complete the trigger of the sensor on the
left front wheel. The trigger means are hand-held low-frequency tool trigger and valve
outlet trigger.
D. After completing c, the pilot returns to the cockpit to check the text reminder of
the instrument. If the interface menu shows successful learning, please exit the sub-
menu to complete the learning process (if you need to continue learning other sen-
sors, please repeat a, b, c, d);
