Tuson TPMS Retrofit Kit User Manual

1. Warning
1.1 Federal Communication Commission Interference Statement:
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in an installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one of the following measures:
01
English
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

1.2.1
Do not operate a TPMS receiver while driving. The company is exempt from all consequences because
of driver’s careless and improper operation.
1.2.2
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 signals. If the insulation adhesive sticker of the windshield contains metal material, it will be likely
to affect reception conditions.If the tire pressure and temperature readings on the TPMS receiver are
displayed as “---”, this condition represents the receiver cannot receive signals emitted by the sensors.
Drive the vehicle away from the current location (nearby there may be signal interference) or drive the
vehicle to a tire shop to check.
1.2 Product Warning
02
English
1.2.4
Temporary resealing or re-inflation products containing internal sealants or propellants in any tire
assembly may adversely affect the operation of the sensor/transmitter. The product manufacturer does
not assume any liability as a result of these.
1.2.5
Do not leave the sensors in contact with chemicals, it may cause the sensors to fail.
1.2.3
If the battery status of the TPMS sensors inside the tire is low (because abnormal conditions continue to
occur, the battery may make the TPMS sensors continuously emit signals to warn the driver, so that
battery life is shorter than the normal life), Please go as soon as possible to the specified service stations
to confirm whether the TPMS Sensors need to be replaced.

The Interchangeable Valve Stem ( IVS ) Service Kit
The Tuson TPMS tire sensor uses a metal interchangeable valve stem (IVS) that fits through 0.453" and 0.625" in.
diameter rim holes. Great for trailer, caravan, motorhome and passenger & commercial vehicle wheels.
Please circle the grommet size that was used for your tire application for easy identification and replacement:
0.453” OR 0.625”
Each IVS service kit comes with two (2) rubber grommet sizes: one (1) fits 0.453” rim holes and one (1) fits 0.625” rim
holes. The IVS should be installed using a single grommet only. Do not use both sizes of the included grommets to install
the valve stem. Please check and make sure that the correct grommet size is used for the valve stem and fits the rim hole
prior to TPMS sensor installation.
Please use the
preassembled 0.625”
grommet on the valve
stem if the rim hole is
0.625”.
When the rim hole of the wheel is 0.453”,
disassemble the valve stem and remove
the 0.625” grommet from the valve stem
and assembly the 0.453” grommet, ring
and nut in order.
The IVS service kit comes
preassembled with the 0.625”
grommet on the valve stem and an
individual 0.453” grommet in the
polybag.

(Fig 1) & (Fig 2) Deflate and remove the tire from the wheel using a tire mounting machine.
(Fig 3) Assemble the sensor to the metal valve stem using the screw (make sure the correct grommet size is on the metal
valve stem), then remove the cap, nut and washer from the metal valve stem.
(Fig 4) Insert the metal valve stem through the rim hole. Then place the back of the sensor body to face the inner surface
of the rim, so that the sensor is parallel to the rim.
(Fig 5) Holding the sensor in place, guide the washer onto the metal valve stem on the outside of the rim hole. Then secure
the nut on the metal valve stem and tighten to 2.95 Ft-lbs (4 N-m) torque. Once secured, affix the cap to the metal
valve stem.
(Fig 6) Secure the sensor to the metal valve stem by tightening the screw to 1.48 Ft-lbs (2N-m) torque.
Now remount the tire back onto the wheel, being careful not to damage the tire pressure sensor during mounting of the
tire.Lastly, balance the wheel as you would normally, adding weights if necessary to achieve rotational balance.

6.2 Installation Steps
The mounting location of the repeater will depend on the type of towable the TPMS will be installed
on. The repeater is designed to repeat the TPMS tire sensors’ RF signals to the receiver in the tow
vehicle. Ideally, to get better RF transmission between repeater and tire pressure sensors, the
repeater should be in an open space and no barriers between tire pressure sensors. Regarding the
repeater specification, please refer to the Chapter 3.3.

7. Driving Mode Menu
When the receiver is turned on, it is in Driving Mode. The screen displays tire pressure, tire temperature
and vehicle battery voltage in sequence. The tire pressure, tire temperature and vehicle battery voltage
are updated on the monitor every 5 seconds.
6.2.1 For travel, cargo or equipment trailers with a bumper pull A-frame hitch, place the repeater onto
the A-frame area of the trailer. Use self-tapping screws to fasten the repeater to one of the two
A-frame members with the “trailer side” black arrow facing the trailer and the power cable end
of the repeater facing the tow vehicle.
For 5th Wheels and gooseneck trailers select a location for the repeater near the house battery.
Use self-tapping screws to fasten the repeater with the “trailer side” black arrow facing the 5th
wheel or gooseneck trailer and the power cable end of the repeater facing the tow vehicle.
6.2.2 Mount the O-ring connectors on the repeater’s power cables to the proper trailer battery
terminals. The RED power cable is to be connected securely to the POSITIVE (+) battery
terminal. The BLACK power cable is to be connected to the NEGATIVE (-) battery terminal.
6.2.3 Use the cable ties to fasten the repeater power cable to the frame of the trailer or 5th wheel.
Avoid a loose repeater power cable by fastening the cable tightly to the frame.
