Overview: The Hella TC-400 is a fully
active radio-controlled system for permanent monitoring of tire pressure and
temperature. 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.
Note: The tire pressure system needs
to be professionally installed.
Wheel Sensors: 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.
LCD Display: 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".
Warning Alerts: 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
- 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.
Hide Away Module: The TC-400 utilizes a
hide-away module that calculates the tire pressure and temperature from the
wheel sensors by RF and then transmits this data to the LCD display unit. The
hide-away unit measures 3.68" wide x 3.741" deep x 1.225" tall. The module
features a 3-pin port for the connection of the units 6.5' power harness and
4-pin port for connection the LCD display's power, ground and data wires. It is
also equipped with a single SMB port for the connection of the supplied 16"
flexible antenna which provides RF data communication between the installed
wheel sensors and the module.
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.
