When you need to register sensors
The TPMS unit remembers the IDs of four sensors. Many Nissan and Infiniti vehicles do not pick up new sensors on their own — until you register them, the TPMS lamp stays on and no pressure is shown.
A second set of wheels
Winter and summer wheels with their own sensors need to be registered again after every swap.
A replaced sensor
The built-in battery died or the sensor was damaged at the tire shop — the new one has to be registered.
New sensors
Original or aftermarket sensors of the right frequency — the app registers any working sensor.
TPMS lamp after a tire shop visit
Wheels were rotated or rims replaced and the unit no longer sees the sensors.
What you need
ELM327 adapter
BLE, Bluetooth Classic or Wi-Fi. For a stable link the author recommends a two-board PIC18 adapter.
TPMS activator
A tool that wakes the sensor with a 125 kHz signal, such as the EL-50448. Registration is impossible without it.
Sensors of the right frequency
315 MHz for US-market vehicles, 433 MHz for Europe and Russia. The frequency is usually printed on the sensor.
How registration works
- 1
Connect to the car
Turn the ignition on, connect the adapter and open “TPMS” on the main screen, then “ID REGIST”.
- 2
Start registration mode
Confirm the start. The app warns that the sensors currently stored in the unit may be erased.
- 3
Front left wheel
Hold the activator against the tire sidewall next to the valve and press the button. In about 5 seconds the wheel turns green on the diagram.
- 4
The other wheels in order
Front right, rear right, rear left. The wheel the app is waiting for blinks on screen.
- 5
Done
The app reports that the TPMS sensors were registered successfully, and the TPMS screen starts showing pressure.
Live pressure in every wheel
The “TPMS unit” screen shows the car diagram with the pressure next to each wheel and a status color: green means the sensor is registered, red means it is not. Pick your units: bar, kPa, psi or kgf/cm². The readings are more precise than the factory monitor, which rounds them, and on cars without a factory pressure display this is the only way to see them.

Model notes
Sensor registration is verified on these vehicles. Find yours — some have details worth knowing.
Infiniti QX80 and QX56 (Z62)
The full set: sensor registration, live pressure in every wheel and the TPMS unit number. The app has been tested on these cars since the first version. Besides TPMS, the Z62 also gets air suspension, hidden BCM settings, transmission and ADAS data.
Everything for this modelNissan Patrol and Armada (Y62)
The Patrol Y62 TPMS unit uses the same procedure as the QX56/QX80. Check the sensor frequency for your market: US-market Armada uses 315 MHz.
Everything for this modelFirst-generation Infiniti QX56 (JA60)
Sensor registration is verified on the first-generation 2004–2010 QX56 as well. Transmission live data does not apply to it: the JA60 has a different, five-speed gearbox.
Infiniti Q70 and M25 / M37 (Y51)
Before 2014 this model was called the M. Q70 and M25 owners registered original sensors: during registration the car flashes the turn signal three times on the side being registered, and the whole procedure takes about five minutes.
Infiniti EX25 / EX35 (J50)
The EX crossover TPMS unit answers on a different address than the QX80 one — the app detects it automatically.
Infiniti FX35 / FX37 / FX50 and QX70 (S51)
From 2013 the second-generation FX was sold as the QX70. Owners have registered both original and aftermarket sensors. Hold the activator exactly as shown in the app: tilting it by a few degrees can keep the sensor from waking up.
Infiniti G25 / G37 (V36)
Verified on the G25 sedan and G37 coupe: owners registered new sensors in a few minutes.
Nissan Quest / Elgrand (E52)
The E52 minivans use their own variant of the registration routine — the app picks it automatically.
Nissan X-Trail (T32)
Sensor registration is verified on the X-Trail T32.
Nissan Serena
The ID REGIST routine was adapted for the Serena separately, starting with version 0.5.3.
Nissan Murano (Z50)
Verified on a 2003 US-market Murano with 315 MHz sensors: the app quickly registered replicas of the original sensors.
Infiniti QX50 and QX60 are not supported yet: they have a newer TPMS unit with a different registration algorithm.
If a wheel does not turn green
Weak activator battery
Replace the activator battery first — it is the most common cause.
Wrong frequency or model
The activator is the wrong model, or the sensors are the wrong frequency (you ordered 433 MHz and got 315 MHz).
Activator on the rim
Hold the activator against the rubber next to the valve, not the rim, exactly as shown in the app.
Cold weather
In frost the sensor signal is too weak. Move the car into a warm garage.
Only one wheel fails
If only one wheel will not register, its sensor is the problem: a dying battery or a faulty sensor. Try it on another wheel.
Verified on these vehicles
Sensor registration and live tire pressure are confirmed on real cars of these models.
