2007 and up Tire Pressure Sensor Relearn
Resetting the TPMS Identification Codes
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle’s tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched to the tire/wheel positions in the following order: driver’s side front tire, passengers side front tire, passengers side rear tire, and driver’s side rear tire using a TPMS diagnostic tool. See your GM dealer for service. The TPMS sensors may also be matched to each tire/wheel position by increasing or decreasing the tire’s air pressure. If increasing the tire’s air pressure, do not exceed the maximum inflation pressure indicated on the tire’s sidewall. You will have two minutes to match the first tire/ wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than two minutes, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over. The TPMS sensor matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to RUN with the engine off. 3. Using the DIC, press the vehicle information button until the PRESS V TO RELEARN TIRE POSITIONS message displays. 4. Press the set/reset button. The horn will sound twice to indicate the TPMS receiver is ready, and the TIRE LEARNING ACTIVE message will display. 5. Start with the driver’s side front tire. 6. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire’s air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which make take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position. To decrease air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. 7. Proceed to the passenger’s side front tire, and repeat the procedure in Step 6. 8. Proceed to the passenger’s side rear tire, and repeat the procedure in Step 6. 9. Proceed to the driver’s side rear tire, and repeat the procedure in Step 6. 10. After hearing the confirming horn chirp for the driver’s side rear tire, the horn chirp will sound two more times to signal the tire learning mode is no longer active. Turn the ignition switch to LOCK. 11. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. 12. Put the valve caps back on the valve stems The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the SERVICE TIRE MONITOR message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. |
Carl, are you saying that there is a sensor located inside the tire itself? Nice write up BTW. I wonder if our Oh5 has this feature. I have not read far enough into the owners encyclopedia (book) yet!

Ah I just haven't read that far in the book yet. I have been resetting most of the previous owners preferences.
Thank you BTW, I found where the ACL is located. Behind drivers side rear wheel up near the frame. |
El-50488 oec-t5
I have a 2007 Escalade and recently tried to relearn the sensors and could not get all 4 to relearn fast enough; kept timing out and having to restart. I did research and found a tool that works well. Its a special GM TPMS Tool (EL-50488 OEC-T5). The tool can be found at the below link. After I opened the package and inserted a 9V battery, not included, it took about 1 minute to relearn all 4 tire sensors and the TPMS lamp went out... it works like a charm, especially if you will be rotating tires, changing out to winter tires, etc... before this tool, I did it manually, according to the steps in the instruction booklet. This last time I tried though, I was frustrated with the manual procedures but did not really want to take it to the dealer. If you're at your wits end with relearning your system... this tool cost me roughly $68.00 plus shipping and handling. Also dont know how many other vehicles it will work with, but it definitely works with my 2007 Cadillac Escalade.
