The TJA1050 error on the Autel iKey820 typically indicates an issue related to the CAN (Controller Area Network) bus communication, specifically involving the TJA1050 CAN transceiver, which is used for vehicle communication. This error can appear due to several potential issues:
Common Causes for TJA1050 Error:Poor Vehicle Communication:
- If the iKey820 is not able to communicate with the vehicle’s ECU or if there is a disruption in the CAN bus network, the TJA1050 error can appear.
- Solution: Make sure the vehicle’s ignition is on, and the OBD-II port is properly connected. Check that the vehicle’s battery is sufficiently charged.
Faulty OBD-II Connection:
- A loose or faulty OBD-II cable/connector can lead to this communication error.
- Solution: Ensure the OBD-II cable is securely connected to both the iKey820 device and the vehicle's OBD-II port. Try reseating the cable or using a different cable to rule out a wiring issue.
Vehicle-Specific Communication Issue:
- Some vehicles might have issues with certain ECU or security modules that are preventing proper communication through the OBD-II interface, causing errors like TJA1050.
- Solution: Check for any issues with the vehicle’s CAN bus wiring or modules. In some cases, the issue could be vehicle-specific and might require further diagnostics.
Software Version Mismatch:
- Outdated software or firmware on the Autel iKey820 might cause compatibility problems with certain vehicles.
- Solution: Ensure your Autel iKey820 has the latest software updates and firmware. Visit the official Autel website or use the device's update feature to keep the tool up-to-date.
Faulty iKey820 Unit:
- There could be a hardware issue with the iKey820 itself, particularly with the CAN bus transceiver component or internal circuitry.
- Solution: If none of the above solutions resolve the issue, consider reaching out to Autel support for troubleshooting or warranty service.
- Check the Connection: Ensure the iKey820 is properly connected to the vehicle and the OBD-II port is clean and free from debris.
- Verify Power: Make sure the vehicle’s battery is in good condition and properly charged. A low voltage may interfere with communication.
- Update the Tool: Make sure your Autel iKey820 is running the latest software and firmware.
- Test with Another Vehicle: If possible, test the iKey820 on another vehicle to rule out a problem with the device or its connection.
- Consult Documentation: Refer to the iKey820’s user manual for further details on the error code and troubleshooting steps, or reach out to Autel’s customer support for assistance.
If you're still facing issues after troubleshooting, contacting Autel technical support would be the next best step to resolve the TJA1050 error.
