Replacing a worn or damaged tire pressure sensor on your Aeolus is straightforward—but the job isn’t done until the car actually sees the new sensor. That step is called TPMS relearn (or sensor registration). Skip it, and your TPMS light stays on, warnings keep buzzing, and you’ll never get accurate pressure readings.
This guide covers every relearn method that works on Aeolus vehicles, the tools you’ll need, and the most common pitfalls to avoid.

Why Relearn? A Quick Primer
Every TPMS sensor broadcasts a unique ID code. When you install a new sensor—like the BL-ST-063 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aeolus, Eπ, Mhero, Nammi, Voyah | OE# E300019160, E300020260, H56A7920001AC BH-Sens 433 MHz sensor (SKU: BL-ST-063)—the vehicle’s TPMS module doesn’t know that ID yet. The act of “learning” that ID (and its position: LF, RF, RR, LR) is called TPMS relearn.
Aeolus vehicles (built by Dongfeng Motor) use a 433 MHz protocol. The BL-ST-063 sensor is pre-programmed with a unique, ready-to-broadcast ID. You do not need to “program” the sensor itself—just teach the car which ID belongs to which wheel.
Three methods can accomplish this:
- Auto relearn (drive-cycle)
- OBD relearn (using a scan tool)
- Stationary relearn (using a trigger tool)
Below I’ll walk through each, including when to use them and exactly what tools you need.

Tools You’ll Need
| Tool | Purpose | Notes |
|---|---|---|
| TPMS scan tool (Autel, Bartec, Launch, etc.) | OBD relearn, sensor activation, diagnostics | Must support Dongfeng / Aeolus protocols |
| TPMS trigger tool | Stationary relearn – activates sensor near the tire | Usually integrated into scan tools |
| OBD-to-TPMS adapter (EL‑50448 clone) | For OBD relearn with aftermarket tools | Some tools work wirelessly; this is an alternative |
| Vehicle owner’s manual | Verify relearn method for your specific model | Aeolus models vary by year and trim |
If you only plan on using the auto relearn method, you need no extra tools—just a steady stretch of road.

Method 1: Auto Relearn (Drive-Cycle)
Most Aeolus vehicles from model year 2018 onward use automatic relearn. The TPMS module listens for new sensor IDs while you drive. Here’s how to trigger it:
- Install the new sensor (torque to manufacturer spec – usually 4 N·m to 7 N·m; check your vehicle manual).
- Set all tires to the correct cold pressure (sticker inside driver’s door).
- Start the engine and drive above 25 km/h (15 mph) for 10–20 minutes straight.
- The TPMS light should turn off by the end of that drive. If it flashes for a few seconds then stays solid, the module is still learning—continue driving another 5–10 minutes.
When it works: On newer Aeolus models (e.g., Aeolus Yixuan, Haohan, Shine, Eπ).
When it fails: On older models, or if you’ve replaced more than one sensor at once (some modules need a manual reset after multiple new IDs).
If the light stays on after 30 minutes of highway driving, move to Method 2 or 3.

Method 2: OBD Relearn (Scan Tool)
This is the most reliable method. You connect a compatible TPMS scan tool to the OBD-II port and follow the manufacturer’s on-screen steps.
Step-by-Step (Works for most Aeolus models)
- Park the vehicle, engine off. Turn the ignition ON (engine does not need to run).
- Locate the OBD-II port (under dash, driver’s side).
- Plug in your TPMS scan tool (or an OBD-to-TPMS adapter like an EL-50448 clone).
- Select “TPMS” → “Relearn” → “Dongfeng” or “Aeolus” from the brand list.
- The tool will instruct you to activate each sensor in order (typically LF → RF → RR → LR).
- For OBD-only tools: the tool sends a command to the vehicle’s TPMS module to accept new IDs. You may need to use a trigger tool to activate each sensor directly—follow the tool’s prompts.
- Once all four sensors are registered, the tool will display “Relearn successful.”
- Confirm by starting the engine: the TPMS light should be off after a few seconds.
Tools that work: Autel TS508/TS608, Bartec Tech400SD, Launch X-431 TPMS, and many universal OBD devices that support Dongfeng protocols. If your tool lists “Dongfeng” or “Aeolus,” it will handle this.
Tip: If you are using a clone device, make sure it has the correct vehicle database update. An outdated database may fail to communicate with newer Aeolus models.

Method 3: Stationary Relearn (Trigger Tool)
Some older Aeolus models (pre‑2018 or specific trims) do not support auto or OBD relearn. Instead, you must physically activate each sensor with a low‑frequency (LF) trigger tool while the vehicle is in “learn mode.”
How to Enter Learn Mode (Stationary)
- Turn ignition ON (engine off).
- Locate the TPMS “learn” button – on most Aeolus models it is hidden behind the glove box, under the steering column, or inside the fuse box cover. Some models enter learn mode automatically after a series of ignition cycles. Check your owner’s manual for the exact procedure – it varies.
- Once the horn honks twice (or the hazard lights flash), the vehicle is in stationary learn mode.
Activate Each Sensor
Use a TPMS trigger tool (or a powerful magnet in very old systems, but 433 MHz sensors usually require LF activation).
- Press the trigger tool against the tire sidewall near the valve stem.
- Hold for 2–3 seconds until the horn honks once (or the TPMS light blinks) confirming that sensor is learned.
- Repeat in the following order: LF → RF → RR → LR.
- After the 4th sensor is learned, the horn honks twice (or the light stays solid) to signal the process is complete.
Important: The trigger tool must be capable of 433 MHz activation (most modern tools do). If you do not own one, you can borrow/rent from a tyre shop.

Which Method Should You Use?
| Condition | Recommended Method |
|---|---|
| Your Aeolus is 2018+ and you replaced only one sensor | Try Auto Relearn first (free, no tools) |
| Auto fails, or you replaced multiple sensors | OBD Relearn (most reliable) |
| You have an older or base‑trim Aeolus | Stationary Relearn (check manual for learn‑mode entry) |
All three methods work with the BL-ST-063 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aeolus, Eπ, Mhero, Nammi, Voyah | OE# E300019160, E300020260, H56A7920001AC BH-Sens BL-ST-063 sensor because it is a standard 433 MHz pre‑programmed unit. No cloning or additional programming is required.

FAQ
Does the BL-ST-063 sensor need to be programmed before installation?
No. The sensor is pre-programmed with a unique ID that broadcasts once power is applied (battery pull‑tab removed). The only step you need to perform is the vehicle relearn (auto, OBD, or stationary) so the TPMS module records that ID.
What if my Aeolus doesn’t have an OBD relearn option in my scan tool?
First, ensure your scan tool’s database is up‑to‑date. Many generic tools label Dongfeng vehicles under “Dongfeng” rather than “Aeolus.” If you still cannot find it, try the auto relearn or stationary relearn methods. Alternatively, visit a tyre shop that has a professional tool (like a Bartec or Autel) with full Dongfeng coverage.
Can I reuse the original TPMS sensor after rotating my tires?
Yes, but you will need to perform a position recalibration (not a full relearn). Many Aeolus models automatically detect sensor positions after a drive‑cycle. If the tire‑pressure warning stays on, use your scan tool to reset the positions without changing sensor IDs.
How long does a stationary relearn take?
Around 5 minutes, plus time to enter learn mode. The hardest part is finding the learn‑mode button or sequence in the owner’s manual. Once in learn mode, each sensor activation takes about 3 seconds.
