Dealing with error codes after modifying your vehicle, especially after removing air suspension, can be frustrating. Many enthusiasts who upgrade their trucks with lift kits and larger tires encounter issues like speedometer inaccuracies, TPMS sensor malfunctions, and persistent “service air suspension” warnings. Fortunately, tools like an OBD2 reader can be invaluable in diagnosing and potentially resolving these problems. This article will explore how an Air Suspension Obd2 Reader can be used to address these common issues.
After installing a lift kit and removing the air suspension system on your truck, it’s common to see a “service air suspension” light. This is because the vehicle’s computer still expects to see the air suspension system functioning. An OBD2 reader, particularly advanced models, can help you communicate with your truck’s computer to address this. Specifically, you may need to use the OBD2 reader to clear the air suspension error codes now that the system is no longer present. This prevents the annoying warning light from constantly appearing on your dashboard.
Beyond just error codes, an OBD2 reader can also be instrumental in recalibrating your speedometer after installing larger tires. When you change tire sizes, your speedometer will likely become inaccurate because it’s calibrated for the original tire size. Some advanced OBD2 readers have functionalities to adjust the tire size parameters within your vehicle’s computer, thus correcting your speedometer readings. This ensures accurate speed measurements and proper functioning of systems that rely on vehicle speed data.

Furthermore, tire pressure monitoring system (TPMS) issues often arise after modifications. If your TPMS sensors are not communicating correctly with your truck after the lift and tire change, an OBD2 reader can assist in re-linking or reprogramming these sensors. This is crucial for safety, as properly functioning TPMS alerts you to low tire pressure, which can be dangerous, especially with larger off-road tires.
In conclusion, an air suspension OBD2 reader is a powerful tool for anyone who has modified their vehicle’s suspension system. It can help clear error codes related to removed air suspension, recalibrate the speedometer for larger tires, and address TPMS sensor problems. While some tasks might require more advanced OBD2 features or specific vehicle knowledge, understanding the capabilities of your OBD2 reader is the first step towards effectively managing your truck’s systems after suspension modifications. For complex issues, consulting a professional mechanic is always recommended to ensure all systems are correctly configured and functioning safely.
