3 out of the 4 pressure sensors are not been realized

[matt76110]

I was at Discounted tires, had all four sensors checked working, but when they tried to reset my "service tire pressure monitor system" message from the DIC, 3 out of the 4 were not reset. Can anyone help me with this situation, what should i do to correct it, at the minimal cost.
Thanks

What happens when you go to each tire in the DIC? Do they show pressures or just "-"? Did you try the relearn procedure (involves letting air out of each tire etc)

yes, they did all of what you said. the DIC only shows one sensor displaying reading, other 3 didn't.

Are they new? This procedure doesn't link up new ones...

2 of the 4 sensors are new - replaced today

Thanks Treehan77 for your reply, here is the update: I pulled the fuse labeled 10A ECC TPM inside the fuse block on the lace side of dashboard, put it back in after a minute, believing it would reset the DIC. Sure it did, I was able to program my remote key which had not been able to lock/unlock car for a while and was not programmable; plus, I gave the sensors one more shot at Discounted tires this morning- all worked! The DIC can display all the reading from each tire and the "service ... Pressure monitor..." Message is cleared.

What did discounted tires do for this last shot?

 

[matt76110]

they used the scanner to reset the sensors, as they tried yesterday. Those sensors were readable, but couldn't be reset at that time.

 

[matt76110]

the scanner does the function same as putting in/letting out air on each tire, resulting a honk after each sensor is reset

 

[matt76110]

forgot to mention, mine is a 06 Tahoe

 

[treehan77]

Right but unless I'm wrong, they would've had to "add" the two new sensors, I don't believe the horn honk thing is capable of doing that right?

 

[matt76110]

I think the DIC treats all sensors the same, as long as the "matching" process is completed. The honk is just confirmation that a sensor has been reset. Anyway, I am glad that I finally found out the trick to solve those two problems. Hope my post will give viewers some aspects to look at when they encounter such problems.
