Understanding 智道 TPMS Relearn
智道 vehicles—part of the Changan-Avtar group—use a direct TPMS system that requires a relearn after sensor replacement, tire rotation, or battery change. The relearn process tells the vehicle’s ECU the new sensor IDs. Since the BL-ST-057 sensor (SKU: BL-ST-057) is pre-programmed with OE-compatible IDs, you only need to trigger the vehicle to accept them.
Three Relearn Methods for 智道
1. OBD Relearn (Fastest Method)
This is the professional approach. Use an Autel TS508, ATEQ VT56, or any OBD tool that supports Changan/智道 TPMS.
Steps:
- Install the new sensor(s) and inflate tires to recommended pressure.
- Turn ignition ON (engine off).
- Connect the OBD tool and select “智道” or “Changan” from the vehicle list.
- Follow the tool’s prompts to “activate” each sensor by placing the tool near the valve stem (driver side front → passenger front → passenger rear → driver rear).
- After activation, the OBD tool sends the new IDs to the ECU.
- Verify TPMS warning light turns off after driving a short distance.
Tools needed: OBD TPMS tool (Autel, ATEQ, Bartec, or clone-supporting device).
2. Stationary Relearn (No Tool Required)
Some 智道 models offer a menu-based relearn without external tools.
Steps:
- With ignition ON, go to Settings → Vehicle → TPMS → Sensor Learn.
- Select “Stationary Relearn” or “New Sensor.”
- Wait 2–3 minutes while the car listens for sensor signals.
- Drive the vehicle above 25 km/h (15 mph) for 1–2 minutes to confirm the IDs.
Note: This method only works if the old sensor IDs are still stored. If the ECU memory is corrupted, you’ll need an OBD tool.
3. Auto Relearn (Driving-Based)
Not all 智道 models support this, but newer ones (2022+) may auto-learn after a battery disconnect or sensor swap.
Steps:
- After installing sensors, drive at steady speed above 40 km/h (25 mph) for 10–15 minutes.
- The TPMS light should blink for 1–2 minutes, then go solid, and finally turn off.
- If the light remains on after 20 minutes, switch to OBD relearn.

FAQ
How do I know if my 智道 supports stationary relearn without tools?
Check your owner’s manual under “Tire Pressure Monitoring System.” Look for “Sensor Learning” or “ID Registration” in the settings menu. If you have a digital instrument cluster (2021+ models), stationary relearn is likely available. For older models (2018–2020), OBD relearn is recommended.
Will the BL-ST-057 sensor work on my 智道 if it has 315MHz instead of 433MHz?
No. The BL-ST-057 is 433MHz only. 智道 vehicles from 2019 onward use 433MHz. Earlier models (2018–2019) may use 315MHz. Check your original sensor’s frequency marking before ordering.
Can I reuse the same OBD relearn tool for other brands like Mazda or Changan?
Yes, most professional OBD tools (Autel, ATEQ) support multiple brands including Changan, Mazda, and Deepal. However, some entry-level clones may be brand-locked. Confirm your tool’s coverage before purchase.
Why does my TPMS light stay on after a stationary relearn?
Possible causes: The sensor was not properly activated, the battery in the sensor is low, or the vehicle’s ECU needs a driving cycle (above 25 mph for 5 minutes). If the light still stays on, use an OBD tool to read error codes—likely a sensor activation failure.
