So i was looking for something in my manual and came across a DIY procedure for relearing TPMS wheel sensors
TPMS Sensor Identification Codes
Each TPMS sensor has a unique identification code. Any time you replace one or more of the TPMS sensors or rotate your vehicle’s tires, 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, passenger’s
side front tire, passenger’s side rear tire, and driver’s side rear tire using a TPMS diagnostic tool. See your 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 one minute to match the first
tire/wheel position, and five minutes overall, to match all four tire/wheel positions. If it takes longer than one minute, 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 procedure is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the engine off.
3. Turn the exterior lamp switch from AUTO to OFF four times within three seconds.
A double horn chirp will sound and the TPMS low tire warning light starts flashing.
The double horn chirp and flashing TPMS warning light indicates the TPMS matching
process has started. The TPMS warning light should continue flashing throughout the
matching procedure. The LOW TIRE message displays on the Driver Information
Center (DIC).
4. Start with the driver’s side front tire.
5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by
increasing or decreasing the tire’s air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position.
If you do not hear the confirming single horn chirp, turn the ignition switch to LOCK
and start over beginning with Step 2. To let 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.
6. Proceed to the passenger’s side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger’s side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver’s side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the driver side rear tire, check to see if the
TPMS low tire warning light and the DIC LOW TIRE messages have turned off. If yes, the TPMS sensors have been relearned. Turn the ignition switch to LOCK.
If the low tire warning light and the DIC SERV TPM messages are on after completing
Step 5 for the driver side rear tire, the sensor relearn process has not been successful.
Turn the ignition switch to LOCK and repeat the matching process beginning with Step 2.
10. Set all four tires to the recommended air pressure level as indicated on the Tire
and Loading Information label.
11. Put the valve caps back on the valve stems.
