Tech 2

Does anyone have access to one? After installing my wheels the increased PSI is causing the DIC to prompt a "check tire pressure" message for each tire at each ignition cycle...

 

[Sepiroth]

I doubt it is due to the larger wheel. What it reads like is that maybe one or more of the pressure sensors arent communicating the correct air pressure.

Did your shop do the proper calibration on the TPSs?

 

[iwaslowr]

The wheels and tires were shipped to me mounted/balanced, etc. so all I had to do was install them. Thereafter the re-learn of the sensors was successful but now the ECM is prompting the DIC to display the "check tire pressure" message because 45-50 PSI is much to high for a stock tire/wheel application....

 

[JennaBear]

Maybe I am reading this wrong, so the person that shipped them to you had the sensors already installed in them?

Correct, the TPMS were included.

I have access to a Tech 2, What sensors did the shipper install? Part #'s? How did you relearn the TPM? Does it give a TP reading? What are they?

Correct, the TPMS were included.

That just might be your problem.

I am not sure what sensors they were... but can find out tomorrow if this is necessary.

How did you relearn the TPM? Does it give a TP reading? What are they?

I followed the Owner's manual re-learn process which was successful. They all give accurate TP readings which is currently ~ 46 PSI cold.

46psi cold is WAY too high. Lower to 32/33 cold and you should be fine.
