Understanding FAW TPMS Relearn Requirements
When you install new TPMS sensors on a FAW vehicle—whether it’s a Bestune X80, B70, or a Hongqi H5—the car’s ECU must “learn” the unique IDs of each sensor. This is not optional: without a correct relearn, the TPMS warning light will stay on, and you won’t get accurate pressure readings.
FAW vehicles use both direct TPMS systems (sensors in each wheel) and, on some older models, indirect systems. For direct systems with 433MHz sensors like the BH-Sens BL-ST-040, the relearn process is straightforward but varies by model year and system generation.
Three TPMS Relearn Methods for FAW
FAW supports three relearn methods. Choose based on the tools you have and the specific vehicle model.
| Method | Tools Needed | Typical Time | Best For |
|---|---|---|---|
| Auto Relearn | None (just driving) | 10–20 minutes | Post-battery replacement or same-sensor reinstall |
| OBD Relearn | TPMS programming tool (e.g., Autel, Bartec, or ATEQ) | 2–5 minutes | New sensor installs, mixed sensor sets |
| Stationary Relearn | Magnet or LF trigger tool (per vehicle spec) | 5–10 minutes | Older FAW models (pre-2016) with magnet-based learn |
Auto Relearn (Drive-to-Learn)
This is the simplest method—no tools required. FAW’s TPMS module automatically learns sensor positions when the vehicle is driven under specific conditions:
- Ensure all tires are inflated to the recommended pressure (check the driver’s door jamb sticker).
- Start the engine and drive the vehicle above 15 mph (25 km/h) continuously for 10–15 minutes.
- The system will automatically detect and assign sensor positions based on wheel rotation patterns.
- The TPMS light should turn off after a successful learn cycle.
Caveat: This method only works if the new sensors have the same IDs as the old ones (e.g., after a battery replacement) or if the TPMS module is in “learn mode.” For brand-new sensors with different IDs, auto relearn usually fails.
OBD Relearn (Tool-Based)
This is the most reliable method, especially when installing sensors like the BL-ST-040 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Bestune, FAW, Hongqi | OE# 3602100FD, 3602100FDA, 3778080DB01A BH-Sens pre-programmed 433MHz unit. You’ll need a compatible TPMS programming tool (most aftermarket tools like Autel MaxiTPMS or Bartec Tech400 work with FAW).
Step-by-Step OBD Relearn:
- Install the new sensors in the correct wheel positions (LF, RF, RR, LR).
- Connect the TPMS tool to the vehicle’s OBD-II port (usually under the dashboard).
- Select FAW from the vehicle menu, then choose the specific model (Bestune or Hongqi).
- Follow the tool prompts to enter “TPMS Relearn” mode.
- Trigger each sensor using the tool’s LF function or by placing the tool near the valve stem and pressing “Activate.” The tool will read the sensor ID and assign it to the correct position.
- Complete the sequence for all four wheels. The tool will then program the IDs into the ECU.
- Verify by checking the TPMS light—it should turn off within a few seconds of ignition on.
Pro tip: Pre-programmed sensors (like the BL-ST-040) save you a step because they already contain the correct 433MHz ID. You only need to register them to the vehicle—no cloning required.
Stationary Relearn (Magnet or LF Trigger)
Some FAW models (particularly 2012–2016 Bestune and Hongqi) use a magnet or LF trigger tool for stationary relearn. This method requires physically activating each sensor in sequence at the valve stem.
For magnet-based systems:
- Turn the ignition to “ON” (engine off).
- Within 10 seconds, press and release the TPMS reset button (usually located under the steering column or in the glovebox). The horn will sound twice.
- Starting with the left front tire, hold a strong TPMS magnet (at least 1500 Gauss) against the valve stem for 2–3 seconds. The horn will sound once.
- Repeat for right front → right rear → left rear (in that order). The horn will sound after each successful trigger.
- After the last wheel, the horn will sound twice, indicating the learn is complete.
For LF trigger-based systems (2016+):
Use a TPMS trigger tool set to “FAW” mode. Place the tool against the tire sidewall near the valve stem and press the trigger button. Follow the same wheel sequence as above.
When to Use Each Method
- Auto relearn: Only for same-sensor swaps (e.g., moving existing sensors to new wheels). Do not rely on this after installing new sensors.
- OBD relearn: Always preferred for new sensor installs. Allows verification of sensor IDs and battery status.
- Stationary relearn: Good for older models or when you don’t have an OBD tool. Requires a magnet or trigger tool.
Recommended Part
For FAW, Bestune, and Hongqi vehicles requiring 433MHz TPMS sensors, the BL-ST-040 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Bestune, FAW, Hongqi | OE# 3602100FD, 3602100FDA, 3778080DB01A BH-Sens BL-ST-040 is a direct-fit replacement. It is pre-programmed with common OE IDs (3602100FD, 3602100FDA, 3778080DB01A) and uses clamp-in installation. Always confirm the sensor frequency and OE number match your vehicle’s original equipment before purchase.
FAQ
Can I use an OBD relearn tool on a 2020 FAW Bestune T99?
Yes, most 2020+ FAW models support OBD relearn via a standard TPMS programming tool. The OBD-II port is located under the driver’s side dashboard. Select “FAW” in the tool menu, then follow the on-screen prompts. If your tool doesn’t list FAW directly, try selecting “Bestune” or “Hongqi” as the manufacturer.
How do I know if my FAW needs a magnet or LF trigger for stationary relearn?
Check the owner’s manual or look for a TPMS reset button (often a small button or pinhole) under the steering column. If you see a button, your vehicle likely uses the magnet method. If there’s no button but the TPMS light is flashing, it may require an LF trigger tool. For 2012–2016 models, magnet-based relearn is common; for 2017 and newer, LF trigger tools are more typical.
What happens if I install a new TPMS sensor without doing a relearn?
The TPMS warning light will remain illuminated, and the system will not display accurate tire pressure readings. In some cases, the vehicle may not recognize the new sensor at all. Always perform a relearn after any sensor replacement. If you’re using a pre-programmed sensor like the BL-ST-040, the relearn process is identical to a new OE sensor.
Can I do a stationary relearn with a regular magnet?
Not all magnets work. You need a dedicated TPMS magnet with a magnetic field strength of at least 1000–1500 Gauss. Standard refrigerator magnets or speaker magnets are too weak. Purchase a TPMS-specific magnet from an auto parts store or tool supplier for reliable results.
