I recently had my PCM recalibrated by PCMforless. I am happy with everything but I discovered an error message(SERV TPM). It came on twice after turning off the cruise control when getting off the interstate. After stopping, it went out. I also noticed my climate control will only blow cold air, or hot air, with no adjustment through the temperature mixing ****. I have hot air on all settings except the coldest. I guess it could be a coincidence but I would check to see if anyone else had this issue before taking the H3 to the dealer.

 

SERV TPM: Tire pressure? Are you running 35+ psi in your tires... if not, this error with a light will pop up on your dash.

Not sure about the second thing, that sounds odd... maybe give PCM4Less a call and ask before you take it to the dealer?

 

Likely unrelated to you PCM flash. Reseat your PCM connections to see if that helps.
