Aftermarket Wheels And Tpms Reset

cablecon · November 24, 2007

I had the stock 20" wheels replaced with 22" wheels with low profile tires to keep outside diameter the same and cannot get the tpms reset. I had horn honk twice and DIC say I was in learn mode. Went to LF and let air out for 30 sec. No horn honk, but kept letting air out then after 2 min it goes out of learn mode. Any suggestions? Thanks in advance

I followed this procedure

1. Take all four valvestem caps off.

2. Find a tool such as a small diameter philips screwdriver that will work to let air out of the valvestem. A common aluminum 1/8" rivet (round end into valve stem) works very well.

2. Add air so that the tire pressures are all 40+ psi (do not exceed the tire's max. inflation rating on the sidewall).

3. Turn key to on position.

4. Apply parking brake.

5. Press and hold lock/unlock down at the same time (for about 3 seconds) on the key fob until the pickup honks.

6. Start at the LF tire.

7. Let air out for 4 seconds - count it out (one one-thousand, two one-thousand, three one-thousand, four one-thousand).

8. Wait for about 15 seconds* for the honk (sometimes it'll honk right away).

9. Repeat 7 and 8 for the RF tire.

10. Repeat 7 and 8 for the RR tire.

11. Repeat 7 and 8 for the LR tire.

12. With all four now done, the system will give it's final multi-honk completion note.

13. Use a quality gauge to set your final pressures (a good gauge will exactly match the sensor readings).

14. Replace all four valvestem caps.

*If you've waited fifteen seconds for the honk and nothing has happened. Don't panic - Simply repeat 7 and 8 again as there is a two minute window to do each tire sensor.

Probably a stupid question, but you did change the sensors over to the new wheels, right?

I rotated the tires on my truck about 2 weeks ago and could not get the relearn to work, called the dealer they said bring it by that they had a tool they just touched to the side of each tire and it relearned the postion. Its agravating when you go through what the book says to do and it doesnt work.
