Why the 轩度EV Needs a TPMS Relearn
The 轩度EV uses a direct TPMS system where each wheel-mounted sensor transmits pressure and temperature data to the vehicle’s ECU. After installing new sensors—like the BL-ST-075 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Chery, Cowin, Jetour, Karry, Soueast | OE# F023114011, F113114011, F113114011BA—the ECU must learn each sensor’s unique ID and assign it to the correct wheel position. Skipping this step leaves the TPMS warning light on and disables pressure monitoring.
Three TPMS Relearn Methods for 轩度EV
1. Auto Relearn (Drive Cycle Method)
This is the simplest method and requires no tools. It works on most 轩度EV models from 2020 onward.
- After installing new sensors, inflate all tires to the recommended pressure (see driver’s door sticker).
- Drive the vehicle above 25 mph (40 km/h) continuously for 10–20 minutes.
- The system automatically learns sensor IDs in a predetermined sequence: LF → RF → RR → LR.
- The TPMS light will turn off after all four sensors are recognized.
Note: This method may fail if the vehicle has been sitting for days or if battery voltage is low. If the light stays on after 30 minutes of driving, proceed to method 2 or 3.
2. OBD Relearn (Fastest Method)
For shops or DIYers with a TPMS tool, this takes under 5 minutes.
- Use a compatible TPMS diagnostic tool (Autel TS508, Bartec, or ATEQ).
- Connect the tool to the vehicle’s OBD-II port (located under the dashboard, driver’s side).
- Select “Relearn” or “Program” in the tool menu, choosing the correct vehicle make (Chery—轩度EV is a Chery sub-brand).
- Follow the tool’s on-screen prompts. Typically, you trigger each sensor by placing the tool near the valve stem (LF, RF, RR, LR order).
- The tool writes the sensor IDs to the ECU. The TPMS light should reset immediately.
Tip: The BH-Sens BL-ST-075 sensor is pre-programmed with OE-compatible IDs, so no sensor cloning is needed—the OBD tool simply assigns the existing IDs to wheel positions.
3. Stationary Relearn (Magnet Method)
Older 轩度EV models (pre-2020) may support this. It requires a strong TPMS magnet (or a rare-earth magnet).
- Turn the ignition to “ON” (engine off).
- Press the TPMS reset button (usually under the steering wheel or in the glove box) until the horn beeps twice.
- Starting at the LF tire, hold the magnet against the valve stem for 3–5 seconds until the horn beeps once.
- Repeat for RF, RR, LR in that order. After the LR horn beep, the system exits relearn mode.
- Drive briefly to confirm the light is off.

Recommended Part
For a hassle-free replacement, use the BL-ST-075 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Chery, Cowin, Jetour, Karry, Soueast | OE# F023114011, F113114011, F113114011BA. It matches the 轩度EV’s 433MHz system and is pre-programmed—no cloning required. Just install and perform one of the relearn methods above.
FAQ
How long does the auto relearn take on a 轩度EV?
It typically takes 10–20 minutes of continuous driving above 25 mph. If the light remains on after 30 minutes, use an OBD tool or check for sensor signal issues.
Can I mix BH-Sens sensors with other brands on my 轩度EV?
Mixing is not recommended. All four sensors should be the same brand and frequency (433MHz). The BL-ST-075 is designed to match the OE protocol exactly, so mixing may cause the system to fail relearn.
Do I need to reprogram the BL-ST-075 sensor before installation?
No. The BL-ST-075 is pre-programmed with OE-compatible IDs. It is ready to install and will be recognized by the vehicle during the relearn process. No additional programming tool is needed.
What if the OBD relearn fails on my 轩度EV?
First, confirm the OBD tool is compatible with Chery/轩度EV (most 2020+ models use standard OBD-II). If the tool can’t communicate, check the OBD port fuse and ensure the ignition is in “ON” position. If still failing, perform a stationary relearn or auto relearn instead.
