Launch CRT 5011E is a powerful and versatile tool offers 98% coverage of global vehicles with tire pressure system. This blog X431shop.de will introduce how to use Launch CRT5011E do TPMS Relearn on Cadillac SRX 2010 year.
*Using the 2010 Cadillac SRX as an example (The dashboard shows an abnormal tire pressure reading of 0 for the left rear wheel, while the actual pressure is 240 kPa. The displayed value does not match the actual tire pressure, and the issue is intermittent. The TPMS warning light is also on.)
Operation Guide
1. Select the Launch CRT5011 device and choose the TPMS (Tire Pressure Monitoring System) function. Based on the information on the vehicle’s nameplate, navigate the menu:
Cadillac → SRX → [2009/11–2011/12 (315MHz)]
Enter the function list and select Activation to activate the TPMS sensors inside the tires.
During activation, it was found that the left rear sensor could sometimes be activated and sometimes not, indicating intermittent failure.
This is diagnosed as a faulty sensor. (Activation failure typically means the sensor is damaged and needs replacement.)

2. Go back to the previous menu and select the Sensor Programming function. Then choose Auto Create to program a Launch TPMS sensor.

3. Replace the faulty TPMS sensor on the vehicle with the newly programmed LAUNCH LF sensor.
4. Go back to the previous menu and click the Activation function again to activate the newly replaced left rear TPMS sensor.
When the device prompts whether to save the activated data, choose to save it; otherwise, you will need to reactivate all sensors.
5. Go back to the previous menu and select the Sensor Relearn function. Follow the on-screen instructions to perform the relearn process.
Once the process is successfully completed, the screen will display a confirmation (as shown in the image below).
Note: OBD Relearn writes the sensor IDs and their positions from the activation interface into the vehicle’s TPMS ECU.
6. After the sensor relearn is successful, click the “OK” button to read the ECU IDs and confirm whether the relearn was completed correctly.
Note: If the sensor IDs and their positions are correct, the text will appear in black. If the position is incorrect, the text will appear in red.
7.On the function selection page, choose the TPMS OBDII function, then select Read DTC (Diagnostic Trouble Codes).
If any fault codes are present, you will need to proceed with the Clear DTC function to erase them.
8.The TPMS sensor was successfully replaced, and the tire pressure display on the dashboard returned to normal. The warning light turned off.
All four tires were inflated to 230 kPa, and a road test was conducted at a speed of 30 km/h or above for 15 minutes.
No abnormal TPMS alerts occurred during the test. The issue has been resolved.
