TPMS System
After the vehicle speed is greater than 25 Km/h, the tyre pressure and temperature information are updated in real time.Four tyre
pressure information in the instrument console and multimedia can timely feedback the tyre pressure and temperature conditions.

5.

TPMS System
The tyre pressure monitoring system only works when the speed is more than 25 km/h; the system will not monitor the tyre pressure state at a
real-time manner when the vehicle is stationary or is running at a speed less than 25 km/h.

Common knowledge for system usage and its maintenance
High pressure alarm
►The pressure signal value of a tyre is equal to or higher than 300 kpa;
►BCM will record the high-pressure alarm DTC of the tyre and set the alarm signal;
►In case of ON or START of IGN, this alarm signal is transmitted to the instrument;
High pressure alarm (processing method)
►Adjusted the tyre pressure to 220 KPA by deflation, and then run the vehicle for 2 minutes at a
speed of more than 30 mile per hour;
►Observe whether the alarm display of the instrument returns to normal;
►If the alarm lamp is off, the problem is solved. If the alarm does not return to normal, please relearn the tyre pressure ID.
胎压过高
Too high tire
pressure
Low pressure alarm
► The tyre pressure signal value of a tire is equal to or less than 165 fixed alarm signal.
►In case of ON or START of IGN, this alarm signal is transmitted to the instrument;
Low pressure alarm (processing method)
►Adjusted the tyre pressure to 220 KPA by inflation, and then run the vehicle for 2 minutes at a
speed of more than 30 mile per hour;
►Observe whether the alarm display of the instrument returns to normal;
►If the alarm lamp is off, the problem is solved. If the alarm does not return to normal, please relearn the tyre pressure ID.
胎压过低
Too low tire
pressure

Common knowledge for system usage and its maintenance
Rapid leakage alarm
►A tyre with a very large pressure drop fluctuation (very large bumps) or a continuous rapid air
leakage will trigger a rapid leakage alarm;
►BCM will record the high-pressure alarm DTC of the tyre and set the alarm signal;
►In case of ON or START of IGN, this alarm signal is transmitted to the instrument;
Low power alarm
►When a sensor is physically damaged and leaks electricity or reaches its service life, it will
trigger a low power alarm.
►BCM will record the high-pressure alarm DTC of the tyre and set the alarm signal;
►In case of ON or START of IGN, this alarm signal is transmitted to the instrument;
轮胎快速泄压
Fast pressure
release of tire
Low power alarm (processing method)
►If a tyre has a low power alarm, please replace the tyre pressure sensor at this position.
►Use 4S shop’s diagnostic instrument to re-learn four sensors, and drive at a speed faster than
30 mph for 5 minutes; if the fault can not be eliminated, replace the BCM;
传感器电量低
Low sensor power

8.

Common knowledge for system usage and its maintenance
Signal loss alarm
►When the vehicle speed is greater than 25KM/H and no effective tyre pressure message for a tyre
position of this vehicle has been received for 10 minutes, an alarm will be triggered at this tyre
position.
►BCM will record the tyre's signal loss DTC and set the alarm signal,
►In case of ON or START of IGN, this alarm signal is transmitted to the instrument;
TPMS信号异常
TPMS signal
abnormality
Signal loss alarm (processing method)
►When the vehicle is subjected to strong radio interference, the fault will be eliminated automatically when it drives away from the interference area.
► In case devices that interfere with the communication of tyre pressure system are installed, such as e-dog, vehicle radio, Bluetooth access card,
driving recorder and car MP3, please remove all these electronic products;
► In case of vehicles stuck with automobile stickers with high metal content that causes wireless shielding and affects the receiving effect of tyre
pressure system, please use automobile stickers without metal content.
► Use 4S shop’s diagnostic instrument to re-learn four sensors, and drive at a speed faster than 30 mph for 5 minutes; if the fault can not be
eliminated, replace the sensor;
If four tyres fail at the same time, please disconnect it from the negative terminal of the storage battery, reset four sensors with the diagnostic
instrument after power-on, and drive at a speed faster than 30 mph for 5 minutes; if the fault can not be eliminated, replace the BCM;

Common knowledge for usage of TPMS system and its maintenance
The TPMS system of SX11 vehicles is equipped with tyre pressure sensor self-learning function, which can automatically locate the tyre pressure
sensor to the correct position by traveling in a non-linear way at a speed of more than 50 km/h for more than 5 minutes.
