Control Unit

Display

4 Sensors

Installation material & instructions

Hella's TC-400 monitors your tire pressure so you can avoid unnecessary fuel consumption, tire, wear, dangerous aquaplaning and lack of traction due to under or over inflated tires. By monitoring your tire pressure while driving, the TC-400 prevents wasted time, money and effort on manual tire pressure check-ups while keeping your hands clean and on the wheel.

The system comes with four wheel sensors that attach to your tire's inner valve that permanently transmit pressure and temperature by radio frequency to the center module receiver which in turn forwards this data to the LCD display unit inside the vehicle. You can add up to three additional sensors giving you a total of seven tire sensors, including one for your spare. All the wheel sensors are pre-programmed and labeled at the factory for a specific wheel location which is used for the first install on your vehicle. Positions are indicated on a label attached to the front of the sensor body (LF, RF, RR and LR). In case of change in wheel location due to tire rotation or spare tire replacement on your vehicle you can use the provided display unit to update the system.

The TC-400 features an LCD display with adjustable background color, allowing you to optimally match the unit's display to your vehicle-specific instrument lighting. You can choose from Blue, Red, Green, Orange, Light Orange, White or Light Blue. The LCD display allows setup of the TC400 Tire Pressure System such as recommended tire pressure and wheel location. It also provides information warnings due to over or under inflation tire pressure. The display comes with a metal mounting bracket that can be attached to a flat surface inside your vehicle by either the supplied two-sided tape or the two supplied mounting screws. You can also choose to mount the LCD display directly to a flat surface inside the vehicle without the bracket using the supplied double-sided tape. The LCD display measures 3.949" wide x 1.577" tall x 0.748" deep. The mounting bracket increases the LCD display's depth to 1.503" and the height to 1.952".

The Hella TC-400 provides warning information that displays in yellow on the unit's LCD display to inform you of tire or system malfunction. A buzzer is also activated during an Alert. The buzzer will repeat and sound again for the duration that the problem has not been fixed. The system features the following Warning Alerts.

Under Inflation Alerts: The TC-400 system is equipped with a 2-stage warning system for under inflation once you have confirmed your factory recommended tire pressure levels. The first warning stage can be adjusted to alert you when your tire pressure drops from 10% to 40% of the factory recommended level. The second warning stage can be adjusted to alert you when your tire pressure level drops from 20% to 50% of the factory recommended level.

Fast Leakage Alert: The TC-400 alerts you if one of your tires looses more than 3PSI within 1 minute.

High Pressure Alert: This warning alerts you when your tire pressure goes above 52 PSI.

High Temperature Alert: The High Temperature Alert warns you when your tire's temperature goes above 185-degrees Fahrenheit.

Signal Loss: If the system does not receive a sensor's signal for more than 10 minutes it will show and Antenna icon on the LCD display to inform you of the malfunction.

While it is recommended that the tire pressure system be professionally installed, it does come with a CD-ROM Instruction Manual. The TC-400's instruction manual is loaded on a supplied CD-ROM. To read the file you must have the Adobe Acrobat Reader software installed on your computer.
