2006 Chevy Tahoe Z71 TPMS Problems

[Phatsalmon]

Thanks for the help in advance. Very frustrated with a constant TPMS light on the dash. When I go to look at the pressures using the buttons on the steering wheel all 4 of the tire pressures are in range on the dash. When using my Xtool D7 the pressures are also correct. When I recalibrate using the "horn beep" method all the wheels get the short beep. With all this being done the TPMS light is still on on the dash board. Any ideas on how I can get this light turned off. The TPMS system is working. Am I over looking something simple?

I'm not familiar with that tool, but will your Xtool read (not just show PIDs) chassis codes? If so, is there one for the TPMS system? Tried another scan tool on it that can read those codes?

The Xtool is not a Snap on but is is very close. I does and will give me all the detail including the make of the sensor. It is reading the sensor location and pressure of each tire. It will also let me set the pressures threshold to other than factory. This is odd. All four are calibrated and the Tahoe is reading the correct pressures. That pesky TPMS light on the dash is on all the time.

FWIW I'd say to try a different advanced scan tool to see if it will read a TPMS code.

See if a tire shop will do a reset.

Does the scantool read out battery levels and such for the sensors?

If it works at the tire shop, you know it is your scan tool.

The Scan Tool is reflecting a TPMS error, but it is showing all the pressures to be fine. All is good except the light is on.

Tire shop has done a reset. I have done a reset. All checks out OK.

Only pressures. They are all good and in range. I will look to see if there is a battery level check for the sensors. There is so much to these tools that sometimes it takes a while to find the correct area.

How does the scan tool show the TPMS error? A code? Screenshot of the tool showing the error?

 

[Phatsalmon]

Scan tool shows all is working fine. Can anyone tell me if this model and year required a TPMS in the spare. It has never had a spare tire TPMS so this is really grasping for straws. I will put one in the spare if required but over twenty years without a TPM in the spare I doubt if it would be required now. Thanks for the help.

Tell us the code that is triggering the TPMS light/error on the dash.

Thanks all for the suggestions. I finally have resolved the issue. Upon a suggestion I changed the type of tire using the scan tool to the standard tire. It was set on class "E". This resolved the issue. I no longer have the TPMS lite illuminated and the DIC is reading all the tires correctly. Not sure if this is a vehicle or a Scan Tool issue but the problem has been resolved. Thanks again
