A Cub Tpms Scan Tool can be invaluable for diagnosing and fixing Tire Pressure Monitoring System (TPMS) problems. However, using the tool incorrectly can lead to complications. This article addresses common issues encountered when using a CUB TPMS scan tool in scan mode versus program mode, specifically focusing on TPMS relearn procedures.
Understanding Scan Mode vs. Program Mode
The core difference lies in the function of each mode. Scan mode is used to activate the TPMS sensors, allowing the vehicle to detect and learn their IDs. This is crucial for proper TPMS functionality after tire rotation or sensor replacement. Program mode, on the other hand, is used to clone or program new sensor IDs. Using program mode incorrectly can overwrite existing sensor IDs, requiring reprogramming by a tire professional. A common mistake is using program mode when attempting a TPMS relearn. This effectively clones the sensors to each other, rendering the relearn process unsuccessful.
TPMS Relearn Procedure with a CUB TPMS Scan Tool
To properly relearn TPMS sensors, ensure the CUB TPMS scan tool is in scan mode. With the vehicle off, exit and close all doors. Re-enter the vehicle and turn the ignition to the ACC or ON position (consult your vehicle’s owner’s manual for the correct procedure). Some vehicles require placing the key fob near the gear shifter and pressing both lock and unlock buttons simultaneously. The vehicle’s display should indicate “Relearn Mode” or a similar message.
Once in relearn mode, do not touch anything inside the vehicle and leave the key fob in the designated position. Begin scanning each tire in the correct sequence (refer to your owner’s manual). The CUB TPMS scan tool will trigger the sensor, sending a signal to both the tool and the vehicle. The vehicle will typically confirm successful learning of each sensor with a horn chirp (single honk for the first three sensors, double honk for the fourth).
Troubleshooting Specific Vehicle Issues
While the general procedure remains consistent, certain vehicles may have specific requirements. For instance, a 2009 Chevrolet HHR using a 2005-2009 Corvette TPMS setting on the scan tool may encounter issues if incorrect sensors are installed. The 2005-2009 Corvette setting should only trigger sensors compatible with those model years. The 2009 HHR utilizes sensors similar to those found in 2010-2013 Corvettes. If the tool triggers sensors in scan mode without the vehicle being in learn mode, it indicates incompatible sensors are installed.
Rectifying Errors: Incorrectly Using Program Mode
If you mistakenly used program mode on the CUB TPMS scan tool, the sensors will need to be individually reprogrammed. Return to the tire shop where the sensors were purchased or installed for professional assistance. They possess the necessary equipment to correctly program the TPMS sensors.
Conclusion
Successfully relearning TPMS sensors hinges on using the correct mode on your CUB TPMS scan tool. Always utilize scan mode to trigger the sensors and allow the vehicle to learn their IDs. Program mode is reserved for cloning or programming new sensors and should only be used by trained professionals. Following the correct procedure ensures accurate tire pressure monitoring and avoids unnecessary trips to the tire shop.
