Understanding TPMS Relearn on the EADO EV
The EADO EV, like many modern electric vehicles, relies on a direct TPMS system. Each wheel houses a sensor that transmits pressure and temperature data to the vehicle’s ECU. When you replace a sensor or rotate tires, the ECU must “relearn” the sensor IDs and their positions. Without this step, the TPMS warning light stays on, and the system won’t display accurate pressure readings.
There are three main methods to perform a TPMS relearn on the EADO EV. The method you choose depends on the tools you have and the vehicle’s specific model year (2018–2024). Always confirm your vehicle’s TPMS reset procedure in the owner’s manual before starting.
Method 1: Auto Relearn (Drive-Away Method)
This is the simplest method and requires no special tools. The EADO EV’s TPMS system can automatically detect and assign sensor IDs as you drive.
Step-by-step:
- Ensure all tires are inflated to the recommended pressure (check driver’s door jamb sticker).
- Drive the vehicle above 25 mph (40 km/h) for 10–15 minutes without stopping.
- The system will learn the sensor IDs and positions during this drive cycle.
- The TPMS warning light should turn off after a few minutes of steady driving.
When it works best: After a tire rotation where sensors are moved to different positions. Not ideal if you installed a new sensor with a different ID than the original.
Method 2: OBD Relearn (Using a TPMS Tool)
For a guaranteed reset, use a TPMS diagnostic tool that supports the EADO EV protocol. This method is faster and more reliable than the auto relearn.
Tools needed:
- Compatible TPMS tool (e.g., Autel TS508, ATEQ VT56, or similar)
- OBD-II connector (included with most tools)
Procedure:
- Turn the ignition ON (engine off, or “Ready” mode on EV).
- Connect the TPMS tool to the OBD-II port (usually under the dashboard).
- Select “Changan” as the vehicle brand, then choose “EADO EV” or “Eado” from the model list.
- Follow the tool’s on-screen prompts to trigger each sensor (usually by holding the tool near the tire sidewall and pressing “Activate”).
- After all four sensors are activated, the tool will send the relearn command to the ECU.
- Turn ignition OFF, then back ON. The TPMS light should extinguish.
Tip: If your tool shows an error, verify the sensor frequency. The EADO EV uses 433MHz. A pre-programmed sensor like the BL-ST-042 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Changan, Kaicene, Oshan | OE# 3601010BK01, 3601010MK01, 3601010MK51 is already set to this frequency, so no manual code entry is needed.
Method 3: Stationary Relearn (Magnetic Trigger)
Some EADO EV models support a stationary relearn using a magnetic TPMS trigger tool. This method is less common but useful if you don’t have a full OBD tool.
Tools needed:
- TPMS magnetic trigger (EL-50448 or equivalent)
- Vehicle key fob (for horn confirmation)
Procedure:
- With the vehicle in “Ready” mode, press and hold the TPMS reset button (usually located under the steering wheel or in the glovebox) for 3 seconds. The horn will chirp twice.
- Starting with the left front tire, hold the magnetic trigger against the tire sidewall near the valve stem. The horn will chirp once to confirm the sensor is learned.
- Repeat for the right front, right rear, and left rear tires (in that order).
- After the last sensor (left rear), the horn will chirp twice to confirm relearn is complete.
- The TPMS light should turn off after a short drive.
Comparison of Relearn Methods
| Method | Tools Required | Time | Best For | Reliability |
|---|---|---|---|---|
| Auto Relearn | None | 10–15 min drive | Tire rotation | Medium – may fail with new sensors |
| OBD Relearn | TPMS diagnostic tool | 5–10 min | Sensor replacement | High – most reliable |
| Stationary Relearn | Magnetic trigger | 10 min | Older EADO EV models | Medium – requires specific steps |
Why Use a Pre-Programmed Sensor?
When replacing a TPMS sensor on the EADO EV, a pre-programmed sensor like the BL-ST-042 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Changan, Kaicene, Oshan | OE# 3601010BK01, 3601010MK01, 3601010MK51 saves time and reduces errors. This sensor comes ready to install with the correct 433MHz frequency and OE fitment for Changan, Kaicene, and Oshan vehicles. You don’t need to clone the original sensor ID or use a programming tool. Simply install it, then perform a relearn using any of the three methods above.
Key specs of BL-ST-042:
- Brand: BH-Sens (Baolong Technology)
- Frequency: 433MHz
- OE Numbers: 3601010BK01, 3601010MK01, 3601010MK51
- Type: Clamp-in, pre-programmed
- Compatible with EADO EV from 2018–2024
Recommended Part
For a hassle-free TPMS replacement on your EADO EV, use the BL-ST-042 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Changan, Kaicene, Oshan | OE# 3601010BK01, 3601010MK01, 3601010MK51. It’s a direct OE replacement that pairs seamlessly with the vehicle’s system. Always verify your specific model year and tire size before ordering.
FAQ
Can I use the auto relearn method after installing a new TPMS sensor?
Yes, but it’s not guaranteed to work. The auto relearn method relies on the vehicle detecting the existing sensor IDs. If you installed a new sensor with a different ID than the original, the system may not accept it. The OBD relearn method is recommended for new sensor installations.
How long does the TPMS light stay on after a relearn on EADO EV?
If the relearn is successful, the TPMS light should turn off immediately after the procedure (OBD or stationary method) or within a few minutes of driving (auto method). If the light stays on for more than 30 minutes of driving, the relearn likely failed.
Is the BH-Sens BL-ST-042 sensor compatible with all EADO EV model years?
It is compatible with most EADO EV models from 2018 to 2024, but there may be exceptions for early production units. Check your vehicle’s original sensor OE number (3601010BK01, 3601010MK01, or 3601010MK51) to confirm fitment. If you’re unsure, consult your owner’s manual or contact support.
