Understanding TPMS Relearn on PASSION Vehicles
PASSION, a rapidly growing Chinese automotive brand under Dongfeng Motor Group, produces several popular models including the Aeolus, Eπ, Mhero, Nammi, and Voyah. These vehicles use direct TPMS sensors that measure tire pressure and temperature in real time. When you replace a sensor or rotate tires, the vehicle’s ECU needs to “relearn” the sensor IDs to their new positions.
The PASSION TPMS system operates at 433MHz and supports three relearn methods. Which one you use depends on the specific model year and available tools.
The Three TPMS Relearn Methods for PASSION
1. Auto Relearn (Drive-Auto Learn)
This is the simplest method and works on most PASSION models from 2018 onward. No special tools required.
Procedure:
- Install the new BL-ST-063 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aeolus, Eπ, Mhero, Nammi, Voyah | OE# E300019160, E300020260, H56A7920001AC in the correct wheel position.
- Inflate all tires to the recommended pressure (check driver’s door jamb sticker).
- Drive the vehicle above 25 mph (40 km/h) continuously for 10–20 minutes.
- The TPMS warning light should turn off after successful learning.
- If the light remains on, continue driving for another 10 minutes.
Limitations: Some PASSION models (especially earlier Aeolus and Voyah) may not support auto relearn. If the light stays on after 30 minutes of driving, switch to OBD or stationary relearn.
2. OBD Relearn (Tool-Based)
This is the most reliable method and works on all PASSION models. You’ll need a compatible TPMS programming tool.
Required Tools:
- TPMS diagnostic tool (Autel TS608, TS508, or Bartec TPMS tool)
- OBD-II connector (included with most TPMS tools)
Procedure:
- Connect the TPMS tool to the vehicle’s OBD-II port (usually under the dashboard, driver’s side).
- Turn the ignition to ON (engine off).
- Select “PASSION” from the vehicle menu, then choose the specific model (Aeolus, Eπ, Mhero, Nammi, or Voyah).
- Select “TPMS Relearn” or “Sensor Programming.”
- Follow the tool’s on-screen prompts to trigger each sensor (usually by reducing tire pressure by 10 psi or using the tool’s LF trigger).
- The tool will send the new sensor IDs to the vehicle’s ECU.
- Disconnect the tool and verify the TPMS light turns off.
Tip: The BL-ST-063 sensor is pre-programmed with OE frequencies, so you don’t need to manually enter IDs — the tool reads them automatically.
3. Stationary Relearn (Magnet or Deflation Method)
This method is used on older PASSION models (pre-2020) or when an OBD tool is unavailable. It varies by model, but the general process is:
Magnet Method (used on Aeolus and Voyah):
- Turn ignition ON (engine off).
- Hold a TPMS magnet (or strong rare-earth magnet) against the valve stem of the left front tire for 5–10 seconds.
- The horn will chirp or the turn signals will flash once to confirm.
- Repeat for right front, right rear, and left rear in that order.
- After the last wheel, the vehicle will confirm with two horn chirps or a solid TPMS light.
- Turn ignition OFF, then start the engine. The light should be off.
Deflation Method (used on some Eπ and Mhero models):
- Start the engine and let it idle.
- Deflate the left front tire to 20 psi (or 20 kPa below recommended pressure).
- Wait 30–60 seconds until the horn chirps once.
- Reinflate to normal pressure.
- Repeat for right front, right rear, and left rear.
- After completion, turn off the engine and restart. The TPMS light should reset.
Fitment Compatibility: BL-ST-063 Sensor vs. PASSION Models
The table below shows which PASSION models support which relearn method with the BH-Sens sensor.
| Model | Auto Relearn | OBD Relearn | Stationary Relearn | OE Part Number |
|---|---|---|---|---|
| Aeolus (2019–2024) | Yes | Yes | Magnet | E300019160 |
| Eπ (2021–2024) | Partial | Yes | Deflation | E300020260 |
| Mhero (2022–2024) | Yes | Yes | Deflation | H56A7920001AC |
| Nammi (2023–2024) | Yes | Yes | Magnet | E300019160 |
| Voyah (2020–2024) | Partial | Yes | Magnet | E300020260 |
Note: “Partial” means auto relearn works only on certain trims. For non-responsive vehicles, always use OBD relearn.
Recommended Part
For PASSION owners replacing TPMS sensors, the BL-ST-063 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aeolus, Eπ, Mhero, Nammi, Voyah | OE# E300019160, E300020260, H56A7920001AC is a direct OE replacement. It’s pre-programmed, clamp-in design, and compatible with all three relearn methods. No additional programming is needed before installation — just install and perform the relearn procedure.
FAQ
Can I use any 433MHz TPMS sensor on my PASSION vehicle?
No. PASSION vehicles require sensors with specific OE part numbers (E300019160, E300020260, or H56A7920001AC). The BL-ST-063 is pre-programmed for these exact OE numbers, ensuring compatibility. Generic 433MHz sensors may not communicate with the ECU.
How long does the auto relearn take on a PASSION?
Typically 10–20 minutes of driving above 25 mph. If the light doesn’t turn off after 30 minutes, the vehicle likely requires OBD or stationary relearn. Some older Aeolus models do not support auto relearn at all.
Do I need to remove the sensor from the tire to program it?
No. The BL-ST-063 sensor is pre-programmed and can be programmed in-wheel using an OBD tool. For the stationary magnet or deflation method, you only need access to the valve stem — no tire dismounting required.
What if the TPMS light blinks after relearn?
A blinking TPMS light (usually 60–90 seconds after startup) indicates a sensor communication error. Check that all sensors are within range (no more than 10 feet from the receiver), batteries are fresh, and the sensor IDs were properly written during relearn. If the issue persists, re-run the OBD relearn procedure.
