Understanding TPMS Relearn on EMGRAND
EMGRAND vehicles (part of Geely’s global lineup) use direct TPMS sensors that transmit pressure and temperature data to the car’s receiver. When you install new sensors—like the BL-ST-073 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BAIC, Baic Ev, GWM, Geely, Geometry & 8 More | OE# 01732445, 25M01A031A, 3641100XKR02A (433MHz, pre-programmed for EMGRAND)—the vehicle’s ECU does not automatically recognize them. You must initiate a relearn procedure to pair the new sensor IDs.
Most EMGRAND models from 2015 onward support three relearn methods. Choose the one that matches your tools and driving situation.
Method 1: Auto Relearn (Drive-Based)
This is the simplest method—no tools required.
- Start the engine and drive the vehicle above 15 mph (25 km/h).
- Continue driving for 10–15 minutes in a straight path with minimal turns.
- The TPMS warning light will blink for a few minutes, then turn off when relearn is complete.
- If the light stays on, repeat the drive cycle once more.
Note: Auto relearn may not work on some EMGRAND models if the battery was disconnected. If the light remains solid after 30 minutes of driving, switch to OBD or stationary relearn.
Method 2: OBD Relearn (Using a TPMS Tool)
For faster, guaranteed results, use an OBD TPMS tool (e.g., Autel TS508, Bartec, or ATEQ).
- Connect the TPMS tool to the vehicle’s OBD-II port (below the steering wheel).
- Turn the ignition to ON (engine off).
- Select “EMGRAND” or “Geely” in the tool menu (depending on your model year).
- Follow the tool’s on-screen instructions to activate each sensor:
- Left front → Right front → Right rear → Left rear (standard order).
- Place the tool’s antenna near the tire sidewall (within 6 inches) and press “Activate”.
- Once all four sensors are activated, the tool will write the IDs to the ECU.
- Turn ignition OFF, then restart the engine. The TPMS light should go out.
Tool compatibility: Most OBD tools support EMGRAND models from 2015–2024. Check your tool’s coverage list for “Geely” or “EMGRAND” if your model is older.
Method 3: Stationary Relearn (Menu-Based)
Some newer EMGRAND models (2020+) allow relearn through the infotainment screen.
- With the engine running, go to the Settings menu on the dashboard screen.
- Select Vehicle → TPMS → Sensor Relearn (or similar wording).
- The system will prompt you to activate each sensor using a magnet or TPMS trigger tool.
- Follow the on-screen steps in the same wheel order (LF → RF → RR → LR).
- After all sensors are recognized, the system will confirm “Relearn Complete”.
Note: If your EMGRAND doesn’t have this menu option, it likely only supports auto or OBD relearn.
Recommended Part for EMGRAND TPMS Replacement
For a hassle-free replacement, use the BL-ST-073 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BAIC, Baic Ev, GWM, Geely, Geometry & 8 More | OE# 01732445, 25M01A031A, 3641100XKR02A. It is pre-programmed with common EMGRAND/Geely IDs, clamp-in design, and operates at 433MHz—matching the frequency used in most EMGRAND models. No cloning or manual programming is needed; just install and perform one of the relearn methods above.
Comparison of Relearn Methods
| Method | Tools Needed | Time | Best For |
|---|---|---|---|
| Auto Relearn | None | 15–30 min drive | Quick, no-tool solution; may fail on some models |
| OBD Relearn | TPMS tool + OBD connector | 5–10 min | Fast, reliable; recommended for shops |
| Stationary Relearn | TPMS trigger tool | 5–10 min | Newer models with menu support |
FAQ
How do I know if my EMGRAND needs a TPMS relearn?
If the TPMS warning light stays on solid after replacing sensors, or if the tire pressures show “—” on the dashboard, the ECU doesn’t recognize the new sensor IDs. A relearn is required.
Can I use the BH-Sens BL-ST-073 sensor on any EMGRAND model year?
The BL-ST-073 (433MHz) fits most EMGRAND models from 2010 onward. However, some 2024+ models may use a different frequency (315MHz or 433MHz with different protocol). Check your vehicle’s original sensor frequency before purchase.
What if the auto relearn doesn’t work after 30 minutes?
Move to OBD relearn. A common cause is a dead battery in the vehicle or a sensor that wasn’t activated properly. Verify each sensor is transmitting by using a TPMS tool to read its signal before starting the relearn.
Do I need to torque the sensor to a specific value?
Yes, always torque clamp-in sensors to 35–40 in-lbs (4–4.5 Nm). Over-tightening can damage the sensor housing; under-tightening may cause air leaks. Check your vehicle’s manual for exact specs.
