Understanding TPMS Relearn on Traum
Traum vehicles, part of the Chery automotive group, use a direct TPMS system that monitors individual tire pressures via sensors mounted inside each wheel. When you replace a sensor, rotate tires, or swap seasonal wheels, the vehicle’s ECU needs to learn the new sensor IDs. This is called a TPMS relearn.
Unlike some European brands that require dealer-level programming, most Traum models support three relearn methods. You do not need to program the sensor itself—pre-programmed sensors like the BL-ST-038 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Chery, Chery Ev, Cowin, Exeed | OE# 802000121AA, 802000126AA, F02361701001AA come ready to install. The only step left is teaching the car which sensor is in which corner.
Tools You May Need
| Tool | Purpose |
|---|---|
| TPMS trigger tool (e.g., Autel TS508, Bartec, or ATEQ) | Activates sensor and reads ID during stationary relearn |
| OBD TPMS tool (e.g., Autel TS608, LAUNCH X431) | Performs OBD relearn without driving |
| Magnet (strong, cylindrical) | Used on some older Traum models for stationary relearn |
| Tire pressure gauge | Verify all tires are at correct pressure before starting |
| Vehicle owner’s manual | Confirm exact relearn procedure for your specific model year |
Step 1: Preparation
Before any relearn procedure:
- Set all four tires to the recommended pressure listed on the driver’s door placard.
- Ensure the ignition is ON (engine may be running or in accessory mode, depending on method).
- Confirm you have compatible sensors. For Traum vehicles, use 433MHz sensors only. The BL-ST-038 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Chery, Chery Ev, Cowin, Exeed | OE# 802000121AA, 802000126AA, F02361701001AA is a direct OE fit for Chery-group models, including Traum.
Step 2: Auto Relearn (Recommended for Most Traum Models)
The auto relearn is the simplest method and works on most Traum vehicles from 2018 onward.
Procedure:
- Park the vehicle on a level surface. Turn the engine off for 5 minutes.
- Start the engine and drive the vehicle above 25 mph (40 km/h) continuously for 10-15 minutes.
- The TPMS system will automatically detect new sensor IDs as the wheels rotate.
- The TPMS warning light should turn off after the drive cycle. If it remains on, repeat the drive cycle at steady highway speed.
Note: Auto relearn may not work if tire positions were changed without moving the sensors. In that case, use OBD or stationary relearn.
Step 3: OBD Relearn (Fastest Method)
If you have a compatible OBD TPMS tool, this method takes under 5 minutes.
Procedure:
- Connect your OBD TPMS tool to the vehicle’s diagnostic port (under the dashboard, driver’s side).
- Select “TPMS Relearn” from the tool menu. Choose your vehicle make (Chery/Traum) and model year.
- Follow the on-screen prompts. The tool will send a command to the ECU to enter relearn mode.
- Activate each sensor in the correct order: Left Front (LF) → Right Front (RF) → Right Rear (RR) → Left Rear (LR). Use the tool’s trigger function to wake each sensor.
- After all four sensors are registered, the tool will confirm “Relearn Complete.”
- Disconnect the tool. The TPMS light should turn off within 1-2 ignition cycles.
Tool tip: Most Traum models respond to standard OBD relearn protocols used by Chery. If your tool lists “Chery” instead of “Traum,” select Chery. The procedure is identical.
Step 4: Stationary Relearn (Magnet Method)
This method is for older Traum models (roughly 2014-2017) or when OBD tool is unavailable.
Procedure:
- With the ignition ON (engine off), press and hold the TPMS reset button (usually located under the steering column or inside the glovebox) until the TPMS light blinks twice. This puts the system into learn mode.
- Starting at the Left Front (LF) tire, hold a strong magnet against the valve stem for 5-10 seconds. The horn will chirp once to confirm the sensor is learned.
- Repeat at Right Front (RF) → Right Rear (RR) → Left Rear (LR) in that exact order. The horn will chirp after each successful registration.
- After the last sensor (LR), the horn will chirp twice to confirm all four are learned.
- Turn the ignition OFF, then start the engine. The TPMS light should remain off.
Important: If your Traum does not have a TPMS reset button, the stationary relearn method may not be available. Use auto or OBD relearn instead.
Recommended Part
For Traum TPMS replacement, use the BH-Sens BL-ST-038 433MHz clamp-in sensor. It is pre-programmed and fits all Traum models that use Chery-group TPMS systems (OE# 802000121AA, 802000126AA, F02361701001AA). No additional programming is needed—just install and perform one of the relearn procedures above.

FAQ
How do I know if my Traum uses auto, OBD, or stationary relearn?
Check your owner’s manual under “Tire Pressure Monitoring System.” If no manual is available, try the auto relearn first—it works on 90% of modern Traum models. If the light stays on after a 15-minute drive, move to OBD relearn with a compatible tool.
Can I use a universal TPMS sensor on my Traum?
Only if the universal sensor is programmable to 433MHz frequency and supports Chery communication protocol. However, pre-programmed sensors like the BH-Sens BL-ST-038 are a safer choice because they match the exact OE specifications and eliminate the risk of programming errors.
Why does my TPMS light stay on after sensor replacement?
The most common cause is that the relearn procedure was not completed. The new sensor IDs must be written to the vehicle’s ECU. Even if the sensors are pre-programmed, the car does not know they exist until you perform a relearn. Also verify that all sensors are transmitting—a dead battery in a new sensor is rare but possible.
How long does a TPMS relearn take?
Auto relearn takes 10-15 minutes of driving. OBD relearn takes 2-5 minutes with the tool. Stationary relearn takes 5-10 minutes, including the time to locate the TPMS reset button and perform the magnet procedure.
