Service Tire Pressure Monitor (TPM)

  

racingrusthotrods -> Service Tire Pressure Monitor (TPM) (3/17/2008 8:52:56 AM)

I picked up a screw in one of my tires on my 2007 2wd crew cab colorado the other day and had it fixed.  At the same time the tire shop topped the tires off to 35 psi from 30 psi. About 30 miles later that day my Service TPM warning came on and since then has been comming on and off intermittently but is on more often then not.  I have checked my tire pressure and it is correct. 

The dealer said that the system most likely just needs to be reprogramed, but that I should plan on being stuck at the dealer ship for at least a couple of hours. 

Does any one know how to reprogram the 2007 colorado TPM system?

I believe that you will find it in the owners manual, page 370.  General process is ignition on with engine off, turn exterior lamp switch from auto to off four times, listen for a double horn chirp, start with left front tire, increase/decrease presure, then right front, right rear, left rear.

Thanks, I found the procedure in my manual on page 390.  I gave it a try and I am not getting a response from the Left Rear, coincidence that this is the same tire that I had the screw, something tells me probably not.  So I guess I need to take on the tire store.  I fear that it may be difficult battle since I went to a Tire Factory, which does not charge for flat repairs which as a result they do not give you a receipt for the work either.  I may start at the dealer since the truck is still under warranty and the sensor did not pickup the low tire pressure when it was around 22 psi prior to the fix.

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.
3. Add air so that the tire pressures are all 40+ psi (do not exceed the tire's max. inflation rating on the sidewall).
4. Turn key to on position.
5. Apply parking brake.
6. Press and hold lock/unlock down at the same time (for about 3 seconds) on the key fob until the pickup honks.
7. Start at the LF tire.
8. Let air out for 4 seconds - count it out (one one-thousand, two one-thousand, three one-thousand, four one-thousand).
9. Wait for about 15 seconds* for the honk (sometimes it'll honk right away).
10. Repeat 7 and 8 for the RF tire.
11. Repeat 7 and 8 for the RR tire.
12. Repeat 7 and 8 for the LR tire.
13. With all four now done, the system will give it's final multi-honk completion note.
14. Use a quality gauge to set your final pressures (a good gauge will exactly match the sensor readings).
15. Replace all four valvestem caps.

*If you've waited fifteen seconds for the honk and nothing has happened. Don't panic - Simply repeat 8 and 9 again as there is a two minute window to do each tire sensor.


**********
the tire shop could have damaged the sensor,  if they do repairs,  with the tire off the rim?

Ended up taking it to the dealer and they found that the Left Rear sensor was dead.  They said that it did not apear damaged so they replaced it under warrany.  The problem is now fixed.  I will definately use the procedure described above on my upcomming tire rotation though.
