TPMS Solar Tire Pressure Monitoring System

1. Introduction

Thank you for choosing the ACCESTING Tire Pressure Monitoring System (TPMS). This system is designed to enhance your driving safety by providing real-time monitoring of your vehicle's tire pressure and temperature. By detecting and alerting you to abnormal tire conditions, the TPMS helps prevent traffic accidents, improves vehicle comfort, reduces tire wear, optimizes fuel consumption, and minimizes the risk of tire bursts.

Please read this manual carefully before using the product. For further assistance, refer to the official user manual PDF: View User Manual (PDF).

Note: While the system effectively monitors tire conditions, it cannot prevent all sudden accidents. Always drive safely and perform regular vehicle maintenance.

2. Key Features

4. Setup & Installation

4.1. External Sensor Installation

1. Install the anti-theft washer onto the tire valve stem.
2. Screw the sensor onto the valve stem.
3. Use the provided wrench to tighten the anti-theft washer by turning it counter-clockwise against the sensor.
4. Ensure the sensor is securely fastened.

4.2. Internal Sensor Installation

1. Separate the tire from the rim.
2. Cut off the rubber at the bottom of the valve stem.
3. Use a screw to temporarily fix the valve, then remove the washer, nut, and dust cap.
4. Mount the sensor onto the valve, adjusting its angle in the wheel hub by hand.
5. Remove the sensor from the wheel hub. Use a specialized tool to tighten the valve in the same location.
6. After tightening the valve, mount it back onto the wheel hub.
7. Mount the washer, nut, and dust cap.
8. Mount the tire and rim, then inflate the tire to the recommended pressure.
9. Perform dynamic balance testing and adjust balance weights as necessary.

4.3. Sensor Pairing / Matching (Filling / Venting)

After installing the sensors, you may need to pair them with the monitor:

1. Press and hold the Left and Right buttons simultaneously for 3 seconds to enter the sensor learning page.
2. Press the 'M' key to select the desired tire position (FR, FL, RR, RL).
3. For external sensors: Reinstall the sensor on the selected tire. For built-in sensors: Inflate or deflate the tire.
4. Upon successful learning, the display will automatically advance to the next position. You can repeat the process for other sensors or long press the 'M' key to exit.

5. Operation

5.1. Power On/Off

• To Turn On: Press and hold the left button for three seconds.
• To Turn Off: Press and hold the left button for three seconds.
• The monitor will automatically power on when it detects car movement (vibration) and power off when stationary.

5.2. Key Functions

• Power Port: Connect the USB charging cable here.
• Left Select Key (<): Used to select menu items or decrease values.
• M (Menu) Key: Long press to enter menu settings; short press to confirm or cycle through options.
• Right Select Key (>): Used to select menu items or increase values.

5.3. Function Settings

To customize parameters, press and hold the 'M' button for 3 seconds to enter the system setup state. If no operation occurs for 30 seconds (or 60 seconds on some interfaces), the system will automatically exit to the main interface, and unsaved settings will be lost. Always press the 'M' key to return to the main interface after completing settings.

1. Unit Setting (Default: BAR / °C):
   Long press 'M' to enter settings. Use Left/Right buttons to select pressure unit (BAR/PSI). Long press 'M' again to exit. To set temperature unit, press 'M' once more, then use Left/Right buttons to select °C/°F. Long press 'M' to exit.
2. Setting Alarm Values (High/Low Pressure, High Temperature):
   Long press 'M' to enter settings. Press 'M' repeatedly to navigate to the desired alarm setting page (e.g., high pressure, low pressure, high temperature). Use Left/Right buttons to adjust the values. Long press 'M' to exit.
3. Tire Change Function:
   Long press 'M' to enter settings. Press 'M' repeatedly to find the tire replacement page. Use Left/Right buttons to select the tire position to be swapped. Long press 'M' to exit.

6. Exception / Alarm Information

The monitor provides visual and audible alerts for various abnormal conditions:

• Gas Leak Alarm: Triggers when tire pressure drops below 1.8 Bar. The buzzer sounds, and the corresponding tire icon, pressure data, and TPMS icon flash continuously.
• High Pressure Warning: Activates when tire pressure exceeds the preset high pressure threshold (default 3.2 Bar). The buzzer sounds, and the corresponding tire icon, pressure data, and TPMS icon flash. The alarm clears when pressure drops 0.1 Bar below the threshold.
• High Temperature Alarm: Sounds when tire temperature exceeds the preset high temperature threshold (default 70°C). The tire icon, temperature data, and TPMS icon flash. The alarm clears when temperature drops 1°C below the threshold.
• Sensor Low Power Alarm: Alerts when any sensor's battery voltage falls below 2.5V. The buzzer sounds, and the tire pressure icon along with the low power icon flash. This alarm will repeat upon reboot until the sensor battery is replaced.

7. Technical Specifications

8. Maintenance

• Cleaning: Wipe the monitor and sensors with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Battery Replacement (External Sensors): External sensors have replaceable batteries (typically CR1632, with a life of approximately 2 years). Refer to the full PDF manual for detailed instructions on battery replacement.
• Charging: Ensure the monitor is regularly charged via solar power or USB, especially during periods of low sunlight.
• Sensor Check: Periodically check external sensors for tightness and ensure they are free from dirt or damage.

9. Troubleshooting

• No Display/Monitor Not Turning On: Check if the monitor is charged. Connect it to a USB power source. Ensure it's not in a completely dark environment if relying on solar.
• No Signal/Sensor Data Missing: Re-pair the sensors following the 'Sensor Pairing / Matching' instructions. Ensure sensors are correctly installed.
• Persistent Alarms: If an alarm (e.g., high pressure, low pressure, high temperature) persists after addressing the tire condition, check the alarm threshold settings and reset if necessary. If a sensor low power alarm persists, replace the sensor battery.
• Inaccurate Readings: Ensure sensors are correctly installed and paired to the correct tire positions. Verify that the tire pressure gauge used for comparison is accurate.

For more detailed troubleshooting steps, please consult the full user manual PDF.

10. User Tips

• Initial Charge: Before first use, fully charge the monitor via USB to ensure optimal battery performance.
• Placement: Place the monitor in a location on your dashboard where it receives ample sunlight for solar charging and does not obstruct your view.
• Regular Checks: Even with the TPMS, it's good practice to manually check your tire pressure periodically with a reliable gauge.
• Alarm Customization: Adjust the alarm thresholds to match your vehicle's recommended tire pressure and your driving conditions for personalized alerts.
