I just had different tires and wheels put on my truck and need to program the TPMS to 50 PSI rather than what the stock was. Does anyone know if this can be done or how to do it without going to the dealer?
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 side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer for
service.
The TPMS sensors can 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.
To decrease air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gauge, or a key. You 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 need to start over.
The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's LOCK and UNLOCK buttons at the same time for approximately five seconds. The horn sounds twice to signal the receiver is in relearn mode and TIRE LEARNING ACTIVE message displays on the DIC screen.
If your vehicle does not have RKE, press the Driver Information Center (DIC) vehicle information button until the PRESS V TO RELEARN TIRE POSITIONS message displays. The horn sounds twice to signal the receiver is in relearn mode and TIRE LEARNING ACTIVE message displays on the DIC screen.
If your vehicle does not have RKE or DIC buttons, press the trip odometer reset stem located on the instrument panel cluster until the PRESS V TO RELEARN TIRE POSITIONS message displays.
The horn sounds twice to signal the receiver is in relearn mode and TIRE LEARNING ACTIVE message displays on the DIC screen.
4. Start with the driver 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 five seconds, or until a horn chirp sounds. The horn chirp, which may take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5. The horn sounds two times to indicate the sensor identification code has been matched to the driver side rear tire, and that the TPMS sensor matching process is no longer active. The TIRE LEARNING ACTIVE message on the DIC display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
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.
Just swapped out my dad's tires just the other day, here are the steps I took
1) Got in the truck and set the parking brake.
2) Turned the key on, yes on and not running. Repeat, not the accessory position.
3) Pushed and held the lock and unlock buttons on the FOB until the horn beeped twice.
4) Stepped out and went to the driver's side front and using the end of a tire gauge deflated the front tire until the horn beeped.
5) Moved to passenger side front and repeated, then passenger rear and finally driver's rear. After the last tire it beeps twice.
6) Went back around and deflated or inflated accordingly.
One observation I did make, The tires with 45 PSI deflated much faster and it took just a few seconds get a beep. The tires at 32 (stock) took MUCH longer to get the beep, so at the lower pressure of a 1500 I would think it would take even longer. Also you have a 2 minute limit per tire so that is why it much easier to deflate then to inflate as you can move around the truck faster. Inflate your tire to 60 PSI and then deflate them to your posted tire pressure you desire, the TPMS is good up to 120 PSI.
