Removal and refitting of tire pressure
sensor
1 - Removal
•Turn off the ignition switch, and disconnect
the battery negative cable.
•Remove the wheels. (Refer to "Removal and
Refitting of Wheels" in this section.)
•Remove the tire with a tire changer (1).
(Refer to "Removal and Refitting of Tires” in
this section.)
CAUTION
•When pressing the bead away from the edge
of the rim, always keep the tire changer
presser 90°above the valve, otherwise the
sensor will be easily damaged.
•Remove the fixing nuts (1) of the tire
pressure sensor with a 11mm socket
wrench.
•Remove the tire pressure sensor with valve
assembly (2).

Tire pressure monitoring system
4.3-11
•Remove the fixing bolts (1) of the tire
pressure sensor with a T10 screwdriver bit
to separate the tire pressure sensor from the
valve.
2- Refitting
•Position the tire pressure sensor (1) and the
valve (2) to refit them in place.
•Tighten the connecting screws (3) of the
valve and the tire pressure sensor with a
T10 screwdriver bit.
•Align the tire pressure sensor (1) with the
mounting holes of the valve to refit it in
place. By applying pressure (you can hold
the sides of the sensor by hands), the
gasket on the valve is tightly fitted to the rim
mounting plane.

Tire pressure monitoring system
4.3-12
•Balance tire pressure sensor (1) and
tighten the fixing nuts (2) of it to the valve
stem.
•Tighten the fixing nuts of the tire pressure
sensor 5 ±0.5N·m with 11mm socket
wrench.
•Refit the tires with a tire changer (1). (Refer
to "Removal and Refitting of Battery").
•After the tire is refitted, inflate the tire and
spray soapy liquid to check if the tire is leaking. If
there is no air leakage, screw on the dust cap. If
the air leaks, find out the cause and re-assemble
it.
•After the assembly is completes, inflate the
tire to the standard pressure (inspect using the
tire pressure gauge).
•Refit the tires to the wheels. (See "Removal
and Refitting of Wheel" in Wheel section.)
•Match the tire pressure monitoring system
after the wheel is installed. (Refer to the "Tire
Pressure Learning" in this section.)
CAUTION
•When refitting the tire with the tire changer,
always keep the tire changer mounting head (1)
90°above the valve, otherwise the tire pressure
sensor may be damaged.

Wireless air leak learning (learning without
tools)
1- Protection
Place protective pads at following locations:
· Front fender;
· Front bumper;
· Driver’s seat;
· Carpet (on driver's side);
· Steering wheel;
· Parking brake lever;
· Shift lever.
2- Learning steps:
CAUTION
•After the tire rotation, replace the tire
pressure monitoring sensor, and do tire
learning after the tire pressure monitoring
control unit has been replaced. When there
is no tool, wireless air leak learning can be
performed.
•With the ignition switch or start-stop button
turned to "ON" position, the tire pressure
information will be displayed on the
instrument cluster display by pressing the
instrument cluster control button.
•Press the hold the instrument cluster control
button“OK”on the steering wheel for 3 s to
enter the tire system learning mode,in this
case, the “Tire Pressure Learning Begins”
will be displayed on the interface.
•If the left front wheel (1) is deflated with air
leakage exceeding 8.25 kPa within 30 s, and
ID learning of left front wheel is completed
by the TPMD control unit, the instrument
cluster will display "Left Front Wheel
Learning Completed" and buzzer will beep
once.
•Follow the above steps to complete the
learning of the right front wheel (2), the right
rear wheel (3), and the left rear wheel (4).
The instrument cluster will display “Right
Front Wheel Learning Completed”, “Right
Rear Wheel Learning Completed” and "Left
Rear Wheel Learning Completed”.

4.3-16
•After the deflation of 4 tires is completed, the
instrument cluster will display “Tire Pressure
Learning Successful”.
CAUTION
•The above learning shall be completed
within 240 s, or TPMS will exit the learning
mode automatically if more than 240 s. IDs
of tires that have not been learned will be
invalid and there will be no information
displayed by the instrument cluster.
•If the tire pressure learning is successful,
increase the tire pressure to the normal
value.
3- Learning flow chart
•The tire pressure wireless learning flow
chart is as follows:
Learning begins
The instrument cluster
sends learning
instructions.
The left front wheel is deflated
until the instrument cluster
displays the relevant
information.
“Left Front Wheel Learning
Successful”
The right front wheel is deflated
until the instrument cluster
displays the relevant
information.
“Right Front Wheel Learning
Successful”
The right rear wheel is deflated
until the instrument cluster
displays the relevant
information.
“Right Rear Wheel Learning
Successful”
The left rear wheel is deflated
until the instrument cluster
displays the relevant
information.
“Left Rear Wheel Learning
Successful”
The instrument cluster displays
“Learning Successful”.
Learnings of 4 tires are completed
within 240 s.
Tire pressure learning
is successful.
Increase the pressure of 4 tires to
the normal value.
Tire pressure learning failed,
and the learning mode will be
exited.
No
Yes

Tire pressure learning (with tools)
1- Protection
•Place protective pads at following locations:
•Front fender;
•Front bumper;
•Driver’s seat;
•Carpet (on driver's side);
•Steering wheel;
•Parking brake lever;
•Shift lever.

3- Tire pressure sensor ID reading
CAUTION
•After the tire rotation, replace the tire
pressure monitoring sensor, and do tire
learning after the tire pressure monitoring
control unit has been replaced. The tire
pressure learning can be performed with
tools if provided.
•Use the "OBD2 to DB9 data cable" to
connect the tool to the vehicle OBD port.
•In the main menu, select the Learn ID by
pressing the Up and Down buttons and
press the ENTER button to enter the Learn
ID interface.
CAUTION
•The OBD2 data cable connector has 16 pins
and the DB9 data cable connector has 9
pins.

4.3-18
•Disconnect the OBD2 to DB9 data cable
between the tool and the vehicle OBD port.
The cursor “→” is at the FL position. The tool
is close to the left front wheel valve position.
Press the ENTER button to wake up the
sensor (it is required to bring the tool close to
the valve at the position of the tire to be
waken up within 5 cm. When the wakeup is
successful, the ID of the sensor at the
corresponding position will be displayed.
•Repeat the Step “2” in the order of the left
front wheel, right front wheel, right rear
wheel, and left rear wheel (clockwise
direction of the vehicle) to complete the
learning of 4 tires.
CAUTION
•Bring the tool close to the valve at the
position of the tire to be waken up within 5 cm
to wake up the sensor.
•If it is necessary to clear the ID of a tire, press
the Up or Down button on the tool to select
the ID to be cleared, and press the ESC
button on the tool to clear the ID data of the
corresponding tire.
•After the sensor IDs of the four tires are all
read, press the Up or Down button on the tool
to make the cursor arrow point to Exit. Press
the ENTER button on the tool to back to the
main menu (the sensor IDs of the four tire at
this time have been saved in this tool.
4- Tire pressure sensor ID writing
•Use the "OBD2 to DB9 data cable" to
connect the tool to the vehicle OBD port.
•Set the ignition switch or start-stop button to
"ON" position.
•In the main menu, select Write ID, press
the ENTER button to write the ID.
“Succeed” will be displayed after the ID is
successfully written, and the interface will
back to the main menu after 3s.
CAUTION
•The OBD2 data cable connector has 16 pins
and the DB9 data cable connector has 9
pins.
5- Tire pressure information activated
•After the ID is successfully written, it is
necessary to update the information of the
new ID in the TPMS (otherwise, the previous
information will still be displayed). There are
two ways to do this:
- Trigger 4 tires again using the Learn ID (in
this case, no order is required).
- The vehicle will automatically update the tire
pressure information if the vehicle travels at a
speed higher than 30 km/h for about 5 min.
