Encountering issues with your BAFX OBD2 scanner and the Torque Pro app can be frustrating, especially when you’re trying to diagnose car problems. Many users, particularly those with older vehicles, face challenges in establishing a stable connection and getting accurate readings. Let’s delve into some common problems you might encounter and how to troubleshoot them effectively, keeping in mind the capabilities of tools like Bafx Obd2 Mode 6 for deeper diagnostics.
One frequently reported message within Torque Pro is “ECU Problem. The ECU is reporting that it does not support the reading of any PIDs.” This alert can immediately raise concerns about vehicle compatibility or scanner malfunction. It’s crucial to understand that this message doesn’t always indicate a faulty scanner. Instead, it often points towards a communication issue between the scanner, your vehicle’s ECU (Engine Control Unit), and the Torque Pro app itself.
Several factors can contribute to this “ECU Problem” message. Firstly, ensure your vehicle is indeed OBD2 compliant. While vehicles manufactured from 1996 onwards in the USA are generally OBD2 compliant, there can be exceptions, especially with vehicles produced in early to mid-1996. The build date of your vehicle and the ECU date can offer clues, but they aren’t definitive proof of OBD2 compliance. Secondly, in rare cases, the OBD2 functionality within the ECU might not be fully enabled or properly communicating.
Interestingly, you might see “connected to ECU OK” at the top of the Torque Pro dashboard while still facing reading errors. This seemingly contradictory message often means that a basic physical connection is established, but the data exchange for specific parameters (PIDs – Parameter IDs) is not functioning correctly. This can result in inaccurate or absent readings on your gauges.
For instance, experiencing an RPM gauge working correctly while other gauges like speed, coolant temperature, and boost pressure are showing incorrect values (like speed being 50% too fast or coolant temperature stuck at -40F) is a classic symptom of PID communication issues. The RPM PID is often a standard and simpler parameter to read, while others might require specific protocols or configurations that are not being correctly interpreted.
Another critical issue reported by users is engine stalling when initiating a fault scan while the engine is running. This is a serious concern and could be related to how the scanner and app are interacting with the ECU’s diagnostic functions in real-time. It’s generally safer to perform fault code scans with the engine off but the ignition turned to the “ON” position. This allows the scanner to communicate with the ECU without the engine actively running, potentially preventing unexpected shutdowns.
Many users also search for solutions like “Power Stroke PIDs” within the Torque Pro app, particularly for Ford diesel engines. Adding custom PIDs can indeed be necessary to monitor specific parameters not included in the standard OBD2 set. However, before diving into custom PIDs and advanced features like BAFX OBD2 Mode 6 data, it’s essential to resolve the fundamental connection and reading issues.
Mode 6 diagnostics, accessible through tools like your BAFX scanner and potentially within Torque Pro (depending on app capabilities and vehicle support), offers in-depth insights into specific system monitors and test results beyond basic fault codes and live data. However, Mode 6 is an advanced diagnostic area. Before exploring Mode 6 for detailed component analysis, ensure you have a stable and reliable connection and accurate basic readings from your OBD2 scanner and app.
In conclusion, troubleshooting BAFX OBD2 scanner and Torque Pro app issues requires a systematic approach. Start by verifying OBD2 compliance and ensuring a solid connection. Address basic PID reading problems before moving on to advanced features like custom PIDs or BAFX OBD2 Mode 6 diagnostics. By methodically addressing potential issues, you can unlock the diagnostic power of your BAFX scanner and Torque Pro app and gain valuable insights into your vehicle’s health.
