Snap-on® TPMS4 Cadillac CTS Manual Relearn

Summary

This video demonstrates how to perform a manual TPMS relearn on a 2011 Cadillac CTS after replacing all four tire sensors. Using the TPMS 4 tool, the presenter walks viewers through putting the vehicle into learn mode via the key fob, then reading and programming each tire sensor individually. The process includes positioning the tool correctly, testing each sensor, and confirming successful programming with audible horn signals and the TPMS warning light turning off. The video provides a clear, step-by-step guide for technicians or car owners to ensure the new sensors are properly recognized by the vehicle's system.

Takeaways

• 😀 The video demonstrates how to perform a manual TPMS relearn on a 2011 Cadillac CTS with snapping sensors.
• 😀 The procedure is necessary after replacing all four TPMS sensors to teach the vehicle about the new sensors.
• 😀 The TPMS TS4 tool is used to perform the relearn process.
• 😀 Users can perform the relearn either as a standalone procedure with the TPMS TS4 or using a diagnostic scanner with TPMS capabilities.
• 😀 For this demonstration, the standalone TPMS TS4 method is used.
• 😀 The vehicle must be put into learn mode by turning the ignition on and pressing both the lock and unlock buttons on the key fob simultaneously until a double chime is heard.
• 😀 Each tire sensor must be read individually using the TPMS TS4 tool by positioning the antenna above the valve stem and pressing the test button.
• 😀 After scanning all four tires, a double chime indicates that the relearn procedure is complete.
• 😀 It is recommended to drive the vehicle briefly until the TPMS warning light goes off to finalize the process.
• 😀 Following these steps ensures that the vehicle correctly recognizes the new TPMS sensors and that the warning light is cleared.

Q & A

What is the purpose of performing the TPMS relearn procedure on a 2011 Cadillac CTS?

The TPMS relearn procedure is done to inform the vehicle's system about the new tire pressure sensors that have been installed. This ensures the vehicle can correctly monitor the tire pressure and show accurate readings.

What tool is being used to perform the TPMS relearn procedure in the video?

The TPMS relearn procedure is being performed using the TPMS 4 tool.

What is the first step to initiate the TPMS relearn procedure on the 2011 Cadillac CTS?

The first step is to turn on the TPMS 4 tool and select the relearn icon, located in the middle of the bottom row of the tool’s interface.

Can the TPMS relearn procedure be performed using a diagnostic scanner instead of the TPMS 4 tool?

Yes, the TPMS relearn procedure can also be performed using a diagnostic scanner with TPMS capabilities. However, in this video, the procedure is demonstrated using only the TPMS 4 tool.

What is the significance of the double horn chime heard during the process?

The double horn chime signals that the vehicle has entered learn mode, which is necessary for the TPMS to start recognizing the new sensors.

How is the left front sensor activated during the relearn procedure?

To activate the left front sensor, the TPMS 4 tool’s antenna is placed right above the valve stem on the sidewall of the tire. The test button on the tool is then pressed to read the sensor.

What should be done after the sensor readings for all four tires are completed?

After the readings for all four tires are completed, the procedure is finalized when the double horn chime sounds again, indicating the relearn process is finished.

What happens if the relearn procedure is performed correctly?

If the relearn procedure is performed correctly, the vehicle’s tire pressure warning light will turn off, indicating that the system is now aware of the new sensors.

Where should the TPMS 4 tool’s antenna be positioned when reading each tire sensor?

The TPMS 4 tool’s antenna should be positioned right above the valve stem and on the sidewall of each tire to read the sensors.

Why is it important to press the unlock and lock buttons simultaneously on the key fob?

Pressing both the unlock and lock buttons simultaneously on the key fob is necessary to trigger the vehicle’s entry into learn mode, which is the first step in the relearn procedure.
