The Autel MaxiTPMS TS508 is a powerful tool for TPMS service, but sometimes users encounter the frustrating “OBD relearn fails” error, often accompanied by “No DTCs.” This article addresses the common causes and solutions for this issue, specifically focusing on Dtc Ts508 Autel.

Understanding the DTC TS508 Autel Error
When the Autel TS508 displays “OBD relearn fails” and “No DTCs,” it indicates a failure to communicate with the vehicle’s ECU during the OBD relearn procedure. While the tool successfully writes sensor IDs, the vehicle’s system doesn’t recognize the new sensor information. This can stem from several issues, hindering proper TPMS functionality. Understanding the root cause is key to resolving the DTC TS508 Autel error.

Common Causes and Solutions for Autel TS508 OBD Relearn Failure
1. Incorrect Relearn Procedure: Ensure you’re following the correct OBD relearn procedure specific to your vehicle’s make and model. Consult your vehicle’s service manual or the Autel TS508 user guide for detailed instructions. Slight variations in the process can trigger the dtc ts508 autel error.
2. Compatibility Issues: Verify that the Autel TS508 is compatible with your vehicle’s year, make, and model. Some vehicles may require specific software updates or may not be fully supported by the TS508.

3. Faulty OBD Connection: Inspect the OBD connector on both the vehicle and the TS508 for damage or debris. A poor connection can disrupt communication and lead to relearn failure. Ensure the connection is secure before initiating the relearn process to avoid the dtc ts508 autel issue.
4. Low Vehicle Battery Voltage: A low battery can interfere with the relearn process. Ensure the vehicle’s battery is fully charged or connected to a charger during the procedure to maintain stable voltage.

5. ECU Issues: In rare cases, the vehicle’s ECU may be malfunctioning, preventing communication with the TS508. If other solutions fail, consult a qualified automotive technician to diagnose potential ECU problems. This could be the underlying cause of the persistent dtc ts508 autel error.
Performing a Test Drive After Relearn
After attempting the OBD relearn, regardless of the outcome, perform a test drive. Drive for at least 10 minutes at speeds over 19 mph (30 km/h). This allows the vehicle’s TPMS system to fully recognize the new sensor IDs and potentially clear any latent DTCs. This step is crucial even if the dtc ts508 autel error persists.

Alternative Relearn Methods
If the OBD relearn continues to fail, try alternative relearn methods, such as “position relearn” or “auto relearn,” if supported by your vehicle. These methods don’t rely on OBD communication and may be successful in registering the new sensor IDs. Consult your vehicle’s service manual for available relearn options.
