Encountering issues with your Autel Ht200 Obd2 scanner? A common frustration arises when users find their car won’t start after disconnecting the device. This situation, while concerning, can often be addressed with a clearer understanding of proper disconnection procedures and potential underlying factors. Let’s delve into this problem and explore effective solutions for smooth operation of your Autel HT200.
Many users rely on OBD2 scanners like the Autel HT200 for reading and clearing diagnostic trouble codes, as well as monitoring live data. The convenience of these tools is undeniable, yet improper usage, particularly during disconnection, can lead to unexpected vehicle behavior. One user reported experiencing a no-start condition after disconnecting their Autel device, highlighting the importance of following the correct steps.
The Autel HT200 manual explicitly warns against disrupting communication during testing, noting potential damage to the vehicle’s ECM (Electronic Control Module). This emphasizes the need to exit all diagnostic functions before disconnecting. The user in question attempted two disconnection methods:
- Exiting diagnostics first, then disconnecting Bluetooth and the dongle.
- Disconnecting Bluetooth first, then exiting diagnostics and the dongle.
In both scenarios, after physically removing the dongle from the OBDII port, the car failed to start. A temporary workaround was found by performing a hard reset (disconnecting and reconnecting the car battery). While this resolved the immediate no-start issue, it’s not an ideal or reliable long-term solution.
This experience raises several important points for Autel HT200 users. Firstly, always ensure you properly exit the diagnostic application on your device before attempting to disconnect. This should terminate the communication link with the vehicle’s ECM in a controlled manner. Secondly, while Bluetooth disconnection is part of the process, the sequence might be crucial. It’s generally recommended to exit the diagnostic software completely before disconnecting Bluetooth and physically removing the OBD2 dongle.
If you are facing a similar “car won’t start” issue after using your Autel HT200, double-check your disconnection procedure against the manufacturer’s recommendations. Ensure you are completely exiting the diagnostic application and allowing a few moments for the system to fully shut down communication before physically disconnecting. If the problem persists even with proper procedures, consider consulting Autel’s technical support for device-specific guidance or seeking advice from a qualified automotive technician to rule out any underlying vehicle-related electrical issues. Remember, proper handling of OBD2 tools like the Autel HT200 is essential for accurate diagnostics and preventing unintended consequences.
