Introduction
The Smart Heavy-Duty Vehicle TPMS Solution is designed to report you the information of tires
on your vehicle. The complete solution includes a Smart Main Unit, TPMS Sensors, a Repeater
and a Trailer Receiver. The Smart Main Unit can automatically search and match the TPMS
Sensors, save your time from repeated and complicated adjustment. The TPMS Sensors detect
the tire pressure and tire temperature in real time, and transmit these data to the Smart Main
Unit through wireless technology. When under-inflation, over-inflation or abnormal
temperature of the tires is detected, the Smart Main Unit will alert you immediately with LED
and audible alarm.
The Smart Heavy-Duty Vehicle TPMS Solution can also work together with the Mobile
Surveillance Solution to further increase the driving security. With a dedicated Receiver Box, you
can also review the information of tires using EverFocus' Mobile DVR, and remotely track,
monitor and manage any type of fleet vehicles using EverFocus’ Xfleet fleet management server
system.

limit is 80°C, when the pressure / temperature of the front-left tire exceeds the limit, the
system will alert you.
The current pressure of the front-left tire is 86psi, lower than the pressure low limit (95psi):
The current temperature of the front-left tire is 85°C, higher than the temperature high limit
(80°C):

The sensors have been paired off with the tires during production. However if the tires are
replaced, you can still pair the sensors with the tires in Learning Mode. You can pair all tires at
once or just pair a single tire.
3.5.1 Pair All Tires
To pair all tires with sensors at once:
1. Put the supplied EV-S01 Battery into the sensor.
2. Turn on the main unit and put the sensors near it, later the main unit can detect the
sensors more easily.
3. In Normal mode, press Temperature Unit button
and Pressure Unit button
for 5
seconds to enter the Learning mode. The backlit turns blue and the system will start to
search the nearby sensors.
17
Smart Heavy-Duty Vehicle TPMS Solution
4. The sensors detected will be displayed on the screen. If you have a total of 6 sensors, the
system should detect at least 6 sensors.

5. Screw the sensors to the corresponding tires follow the installation order. (See 2.2 Sensor
Installation)
3.5.2 Pair a Single Tire
To pair a single tire with a sensor:
1. Turn on the main unit. In Normal mode, press Temperature Unit button
and Pressure
Unit button
for 5 seconds to enter the Learning mode. Press Unit button
again to
enter the tire order selection mode. In this mode, use Unit button
to select the tire
order.

2. Put the supplied EV-S01 Battery into the sensor then put the sensor near the main unit, the
system will start to search the nearby sensor which is powered but is not receiving any tire
pressure.
3. After the sensor is detected, screw the sensors to the corresponding tire (See 2.2 Sensor
Installation).
4. When the sensor is successfully paired with the tire, the main unit will beep and its
backlight will flash, then the system will returns to Normal mode.

5. Troubleshooting


Main unit does not receive any signal from sensor:
1.
Remove the sensor from the tire, and see if the main unit receive the signal from the
sensor.
2.
If the main unit does not receive any signal, put the sensors near the main unit,
remove the EV-S01 Battery from the sensor and then put it into the sensor again.
3.
If the main unit still does not receive any signal, the sensor may not be paired correctly
or the sensor’s battery may be out of power.
Below information appears on the main unit with flashing red backlight and audio alarm:
The system is notifying you that the tire pressure of the current tire is too high (based on
the default tire pressure high limit 145psi).

1.
Check the tire temperature of the current tire. When the tire temperature is too high,
the tire pressure may also increase.
2.
If the tire temperature is normal, check the cold tire pressure. When the cold tire
pressure is too high, the tire pressure may also increase. Adjust the cold tire pressure
to 120±5psi when you have a vehicle maintenance.
Below information appears on the main unit with flashing red backlight and audio alarm:
The system is notifying you that the tire temperature of the current tire is too high (based
on the default tire temperature high limit 85°C).
21
Smart Heavy-Duty Vehicle TPMS Solution

1.
Check the brake. When you hit the brakes too often or the brake does not work
correctly, the tire temperature may increase.
2.
Slow your driving speed, and arrange a vehicle maintenance as soon as possible.
Below information appears on the main unit with flashing red backlight and audio alarm:
The system is notifying you that the tire pressure of the current tire is too low (based on
the default tire pressure low limit 100psi).

1.
If the tire pressure keeps decreasing and the tire temperature keeps increasing, slow
your driving speed, inflate the tire, and arrange a vehicle maintenance as soon as
possible.
2.
If the tire pressure keeps decreasing yet the tire temperature does not increase, adjust
the cold tire pressure to 120±5psi when you have a vehicle maintenance.
Below information appears on the main unit:
The system does not receive the signal from the current tire.
1.
Running the vehicle and see if the information appears again.
2.
The sensor’s battery voltage may be too low.
3.
The sensor may be damaged or missing.
4.
Leaves the current area and see if the information appears again.
22
Smart Heavy-Duty Vehicle TPMS Solution

Below information appears on the main unit:
The system does not receive the tire pressure from the current tire.
1.
Check the tire pressure of the current tire.
2.
Make sure the valve thimble is installed properly.



No information displayed on the screen:
1.
Check the power connection to the main unit.
2.
Check the fuse to the main unit.
The main unit only displays information of certain tires:
The main unit will focus on the tires which have abnormal pressure or temperature. Check
the tire pressure, temperature and sensor’s battery voltage of the current tire.
