Torque Pro is a popular app for Android devices that allows users to monitor various vehicle parameters using an OBD2 Bluetooth adapter. While many newer vehicles are readily compatible, using Torque Pro on a 1996 vehicle, which is among the first model year to feature OBD2, can present some challenges. This article explores using Torque Pro with a 1996 OBD2 vehicle and offers potential solutions to common issues.
A user with a 1996 GMC K2500 equipped with a 5.7 Vortec engine and a 4L80E transmission recently shared their experience with Torque Pro. Initially, they were unable to retrieve transmission temperature data, even though the corresponding PID (Parameter ID) was available within the app. Similarly, the torque PID also failed to provide any data.
One potential issue with 1996 vehicles is the limited number of PIDs supported by the factory ECM (Engine Control Module). Compared to later OBD2 vehicles, early models often transmit less data. Furthermore, even if a PID is listed in Torque Pro, the vehicle’s ECM might not actually broadcast that specific data point.
Another challenge lies in the communication protocols used by early OBD2 systems. Some 1996 vehicles might not fully adhere to the standardized OBD2 protocols used by Torque Pro. This incompatibility could lead to difficulties in retrieving data. Using a reliable OBD2 Bluetooth adapter specifically designed for compatibility with older vehicles is crucial.
The user later reported success in obtaining transmission temperature readings after modifying the equation within Torque Pro to display Fahrenheit instead of Celsius. They also noted that the torque readings initially displayed in kilowatts (kW) required conversion to foot-pounds (ft-lbs). However, these issues seemingly resolved themselves after restarting the app and the vehicle, highlighting the importance of basic troubleshooting steps.
To maximize the chances of success with Torque Pro on a 1996 OBD2 vehicle, consider the following recommendations:
- Choose a compatible OBD2 adapter: Opt for a reputable brand known for its compatibility with older vehicles. The user in this case successfully used a Bafx Bluetooth OBD2 reader with a 3-foot extension cord. An extension cord can be helpful to minimize interference and provide easier access to the OBD2 port.
- Consult online forums: Forums dedicated to specific vehicle makes and models often contain valuable insights and custom PIDs created by other users who have successfully accessed data from similar vehicles. The user referenced a thread on GMT400.com, a forum dedicated to GM trucks, which provided guidance on configuring Torque Pro for a 1996 K2500.
- Experiment with different settings: Torque Pro offers various customization options. Experimenting with connection settings, PID configurations, and data display formats can sometimes resolve data retrieval issues.
- Ensure proper grounding: A poor ground connection can interfere with OBD2 communication. Verify that the OBD2 adapter and the vehicle’s electrical system are properly grounded.
While using Torque Pro on a 1996 OBD2 vehicle can present challenges, success is possible with the right adapter, proper configuration, and a bit of persistence. Leveraging online resources and community forums can prove invaluable in overcoming compatibility hurdles and unlocking the full potential of Torque Pro for diagnosing and monitoring your vehicle.
