1. Introduction

1-1 Scope of System Application

Tire pressure monitoring system-C2(TPMS C2) is a device installed on

the valve and detect tire pressure and temperature in real-time then the

detecting value will be transmitted to the receiver with RF wireless. The

driver can read the condition of vehicle and reduce the rate of accident

happening.

The device needs to be installed by qualified personnel in accordance with

installation manual to enjoy related warranty. The system is suitable for

sedan tire (under 3.5 ton) and 60psi the maximum detectable pressure (420
Kpa). When the system displays a warning light and warning “beep“

sounds. When the system displays a warning light and beep to warn, The

driver should immediately slow down, stop in a safe location and check the

tire condition, and find a qualified tire maintenance station to repair.

1-2 Safety Notice

1. The kind of chemicals used in various types of sealants and tire filling

might affect the operation of the TPMS sensor and TPMS receiver and

can lead to shortened life of sensor valve.

2. Tire pressure monitoring system (TPMS) is auxiliary driving safety

equipment, which cannot detect tire condition. The driver must still

regularly check tire condition.

3. The system adopts the wireless transmission of signals. In some special

circumstances, interference or erroneous methods of operation or

installation method errors may cause weaker signal or its inability to

receive signal. For example, choose the qualified socket extension

4. The driver has to get into good driving habits and regular maintenance

of the vehicle’s major systems. Then it will have a better performance

on average fuel consumption

5. Annual periodic inspection for the “sensor valve” is proposed, which

should be replaced immediately if damaged, in order to avoid air leakage.

The driver should immediately slow down, stop in a safe location and

check the tire condition, and find a qualified tire maintenance station to

repair.

1-3 Why TPMS? Why Picolink?

Why TPMS?

 Improve fuel economy up to 2-5%
 lower the level of tire wear by 20~30%
 Decrease the probability of flat tire
 Maintenance cost saving
 Mandatory equipment for new car-Seat belt, Third brake light and

Tire pressure monitoring system

Why Picolink?

 Breaking through the limitation of material and distance then create

the only TPMS with aluminum alloy frame.

 Applying chipset made by best chip-maker in German ─ Infeneon

and well-known Swiss batteries-Renata

 Pressure endurance of external valve is up to 100 Psi
 Easy instllation and quick operation

5-2 Rotation Settings (External)

Method 1

 Remove four sensors from valve firstly then let technician do tire

rotation. After tire rotation is done, install the sensors in sequence

which can refer to 5-2 sensor installation.

Method 2

 Do tire rotation without removing any sensors. After tire rotation is

done, hold down【Set】and 【Mode】in the same time for over 3

seconds then the system will enter into tire rotation settings mode.
Press【Mode】 again can exit the mode.

 The receiver display〝1〞 means the system enter into the setting of

NO.1 RF (right-front tire) and so on.

 The setting have to follow the sequence- NO.1 RF(right-front tire)→

NO.2 RR(right-rear tire)→ NO.3 LR(left-rear tire) →NO.4

LF(left-front tire). When you start doing setting, you can exit the

mode only after the above setting had finished in sequence.

A. NO.1 RF (right-front tire) settings

- Doing the settings when the receiver display〝1〞and the tire icon

flashes the green light(Fig.1).

- Remove the battery from the sensor of right-front tire then install

the battery back instantly. Hearing the beeping sound means the

setting is done.

- If the right – front tire no needs to set , press【Set】to skip settings and

enter into NO.2 RR (right-rear tire) settings (Fig.2).

7. Troubleshooting

1. Why does the display show “E1“?

The surrounding electromagnetic wave jams the transmission and

connection of receiver then leads the receiver unable to work. Pull the
receiver out and re –plug it into cigarette lighter and if still can’t

work after 10minutes,please contact with maintenance department.

2. Why does the display show “E2“?
It means the sensor’s battery is getting low.

3. How to know the stander tire pressure for my car?

You’ll find the manufacturer’s optimum or recommended tire
pressure for your car on a sticker in the door jam, or in your owner’s

manual. Some models even place the stickers on the trunk lid, in the

console or on the fuel door.

4. Is that normal that tire pressure value is different when I measure it by

traditional tire pressure gauge and TPMS separately?

That’s normal. The traditional tire pressure gauge needs to be

adjusted frequently to keep measurement correct. As for TPMS, it’s

electronic detection making measurement precise and keeping the
tolerance to stay in ±1psi.

5. How to reset the setting after the battery of sensor is changed?

Please refer to chapter5-2 “Rotation Settings”.

6. Is the sensor unable to work if batteries are dead?

Yes. The driver can confirm which battery is getting low from the

receiver. For external sensor user, you can just buy CR1632 battery to
replace and refer to chapter 5-2 “Rotation Settings” to set up.

7. Dose the sensor need to be removed as doing tire rotation?

No, it doesn’t. Please refer to chapter 5-2 “Rotation Settings”.

鉅連通科技股份有限公司

8. Can I adjust pressure and temperature value on my own?

The product has default settings, but it allow the driver to adjust

depends on the trait of tire.

9. When dose TPMS start to monitor?

TMPS will detect tire as engine is starting and car is moving.
