Encountering problems with your BAFX OBD2 scanner and the Torque Pro app can be frustrating, especially when you’re trying to diagnose car issues yourself. Many users face challenges in establishing a stable connection and getting accurate data. This article will guide you through troubleshooting common problems experienced with BAFX OBD2 adapters, focusing on the dreaded “ECU Problem” message and inaccurate readings.
Understanding the “ECU Problem” Message
One common error message users encounter is: “ECU Problem. The ECU is reporting that it does not support the reading of any PIDs…” This message suggests a few potential issues that prevent your BAFX OBD2 scanner from communicating effectively with your vehicle’s Engine Control Unit (ECU).

Firstly, the message may indicate a compatibility problem. While vehicles from 1996 onwards are generally OBD2 compliant, there might be exceptions or specific models that don’t fully adhere to the standard. It’s also possible, though less likely in a 1996 vehicle, that the OBD2 functionality on your ECU hasn’t been fully enabled.
Troubleshooting Connection and Data Reading Issues
Even when Torque Pro indicates “connected to ECU OK,” you might still experience issues with data accuracy. A frequent problem is inaccurate readings from gauges, as described by a user with a 1996 truck:
-
RPM Gauge Works, Others Don’t: If your RPM gauge is the only one providing correct data, while others like speed, coolant temperature, and boost are incorrect or static, it points to a partial communication issue or incorrect PID settings.
-
Speed Gauge Inaccuracy: A speed gauge reading double or half the actual speed suggests a misconfiguration in the app or a PID issue.
-
Coolant Temperature at -40F: A constant reading of -40F for coolant temperature usually indicates the app is not receiving data from the sensor, or is using an incorrect PID.
-
Boost Stays at Zero: If your vehicle is turbocharged and the boost gauge remains at zero, it’s another sign of incorrect data or a communication problem with the relevant sensor.
-
Truck Stalling During Fault Scan: Experiencing engine stalling when initiating a fault scan, especially while the engine is running, is unusual and could indicate a deeper communication conflict. Scanning for faults with the key in the “ON” position, engine off, is generally a safer approach.
Potential Solutions and Next Steps
To resolve these BAFX OBD2 and Torque Pro issues, consider these troubleshooting steps:
-
Verify OBD2 Compliance: Double-check your vehicle’s make, model, and year to confirm OBD2 compliance. While 1996 vehicles are generally OBD2, confirm specific details for your truck.
-
Check Torque Pro Settings: Ensure Torque Pro is correctly configured for your vehicle type. Explore Torque Pro settings for vehicle profile and adapter settings to rule out misconfigurations.
-
PID Settings and Power Stroke PIDs: Investigate custom PID settings within Torque Pro. For specific vehicles like Power Stroke diesel engines, there might be custom PID sets available online that can improve data accuracy. Search online forums and communities for “Torque Pro Power Stroke PIDs” to find potential custom configurations.
-
Test on Another Vehicle: If possible, test your BAFX OBD2 scanner and Torque Pro app on a different OBD2 compliant vehicle. This can help isolate whether the issue lies with the scanner itself or your specific truck.
-
Seek Expert Advice: If troubleshooting steps don’t resolve the issues, consider seeking advice from online forums dedicated to Torque Pro and OBD2 diagnostics, or consult a professional mechanic experienced with automotive diagnostics.
By systematically troubleshooting these potential issues, you can often resolve connection problems with your BAFX OBD2 scanner and Torque Pro app, gaining valuable insights into your vehicle’s health.
