Understanding TPMS Relearn on BOX Vehicles
BOX (Toyota‘s subcompact brand) uses direct TPMS systems across most models. When you replace a sensor, rotate tires, or swap wheels, the vehicle’s ECU must learn the new sensor IDs and their positions. Skipping this step triggers the TPMS warning light and disables the system.
The relearn procedure depends on your BOX model year and trim. Newer models (2018+) support auto relearn, while older ones require OBD tool or stationary methods. Always confirm your specific model’s procedure in the owner’s manual.
Three TPMS Relearn Methods for BOX
1. Auto Relearn (Drive-Only Method)
The simplest method—no tools needed. Works on most BOX models from 2014 onward.
Procedure:
- Inflate all tires to the recommended pressure (check driver’s door sticker).
- Start the engine and drive the vehicle above 30 mph (48 km/h) for 10-15 minutes.
- The TPMS system automatically detects sensor positions based on wheel speed and signal strength.
- The TPMS light should turn off after successful relearn.
Notes: Auto relearn may fail in cold weather or if sensors have weak batteries. If the light stays on after 15 minutes of highway driving, switch to OBD relearn.
2. OBD Relearn (Tool Required)
Reliable for all BOX models. Requires a TPMS programming tool like Autel TS508, Bartec TPMS Tool, or ATEQ VT56.
Procedure:
- Connect the OBD tool to the vehicle’s diagnostic port (under the dashboard).
- Select “TPMS Relearn” and choose your BOX model and year.
- Activate each sensor using the tool’s LF (low-frequency) trigger or by holding the tool near each tire valve stem (follow tool prompts).
- The tool sends sensor IDs to the ECU via OBD.
- Disconnect the tool and test drive for 2-3 minutes to confirm.
Compatibility Table:
| BOX Model Year | OBD Relearn Supported | Auto Relearn | Stationary Relearn |
|---|---|---|---|
| 2010-2013 | Yes (with compatible tool) | No | Yes |
| 2014-2017 | Yes | Yes | Yes |
| 2018-2024 | Yes | Yes | No (OBD only) |
3. Stationary Relearn (Magnet Method)
Older BOX models (2010-2017) support this method. You need a strong magnet (TPMS magnet or rare earth magnet).
Procedure:
- Set parking brake and turn ignition to ON (engine off).
- Locate the TPMS reset button (usually under the steering column or in the glovebox). Hold it until the TPMS light blinks twice.
- Starting with the left front tire, hold the magnet against the valve stem for 5-10 seconds until the horn honks once.
- Repeat for right front, right rear, left rear (in that order). Each tire honks once.
- After the left rear tire, the horn honks twice to confirm completion.
- Turn ignition OFF, then start the engine. The TPMS light should go out.
Recommended Parts for BOX TPMS Service
When replacing sensors on BOX vehicles, use a compatible 433MHz sensor like BL-ST-014 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Lexus, Subaru, Toyota | OE# 28103CC010, 4260702060, 4260702070. This BH-Sens sensor (Baolong Technology) directly replaces OE numbers 28103CC010, 4260702060, and 4260702070. It supports all three relearn methods and fits Lexus, Subaru, and Toyota models as well—useful if you service multiple brands.
Installation Tips:
- Replace the rubber valve stem and metal nut when installing a new sensor.
- Use a torque wrench on the valve nut (check your manual, typically 3-5 Nm).
- Write the sensor ID on the inside of the tire for future reference.
FAQ
Can I use a universal TPMS sensor on my BOX vehicle?
Yes, programmable universal sensors like the BH-Sens BL-ST-014 work on BOX vehicles. You need to program the sensor with the correct frequency (433MHz) and OE ID before installation. Most TPMS tools can clone the original sensor’s ID or program a new ID.
How do I know if my BOX TPMS sensor is bad?
Symptoms include a flashing TPMS light (sensor failure) or a solid light (low pressure or incorrect relearn). If the light stays on after proper tire inflation and relearn, one or more sensors likely have dead batteries. Sensor battery life is typically 5-7 years.
Do I need to relearn TPMS after tire rotation?
Yes—if your BOX model uses position-specific sensors (most do after 2010). Without relearn, the system displays pressures in the wrong positions (e.g., showing left front pressure for the right rear tire). Auto relearn handles this automatically if you drive for 10-15 minutes.
Can I do a stationary relearn on a 2020 BOX?
No. BOX models from 2018 onward require OBD relearn or auto relearn. The stationary magnet method is not supported. Use a TPMS tool or drive the vehicle at highway speeds for 15 minutes.
