How to Rewrite the TPMS Sensor ID for 431?
3 Answers
Select the Toyota version, choose the diagnostic port, select auto search, and then choose others. Based on the model year, select the appropriate time. Depending on whether the vehicle has a smart key, select 'No Smart Key,' then enter the original ID5 code 13527c9. Once prompted that the writing is successful, the process is complete.
I just finished researching the topic of TPMS sensor ID reprogramming, and the differences between brands are quite significant. For Japanese cars, you usually need to connect the manufacturer's diagnostic tool to the OBD port. European and American models often require specialized programming equipment. The key point is that the sensor position identification code must be re-paired with the vehicle's computer - otherwise, a warning light might be the least of your problems, with potential ABS interference in severe cases. Always verify sensor compatibility before proceeding - my neighbor's Mercedes kept giving false alarms because of aftermarket sensors. If you're unsure, it's best to visit a dealership; their professional equipment can handle all four wheels in about 30 minutes. For DIY attempts, remember to calibrate tire pressure to factory specifications before initiating the matching process.
Last month, I helped a friend modify the sensor ID and discovered several key points. First, the car must be parked in an area with minimal signal interference. Then, follow the corresponding operation process based on the vehicle model. Some cars require triggering the sensors in a specific sequence (front left → front right → rear right → rear left) and must be completed within a limited time. During the matching process, continuously monitor the feedback from the diagnostic tool, paying special attention to signal strength—if it drops below 70%, repositioning is necessary. After completion, a road test is essential for verification. Once, I skipped this step, and the next day while driving on the highway, the tire pressure monitoring system suddenly failed, which was extremely dangerous. Nowadays, newer car systems have higher encryption levels. For example, the latest Toyota models require the original TechStream software to make modifications.
