Unspecified TPMS fault

Hi Everyone,

I recently got this fault but it's so vague I'm not sure where to start. The only information is the message, "TIRE MONITORING SYSTEM FAULT."

I pulled all of the codes using my IID tool but I don't see anything related to the TPMS.



Any suggestions on where to start looking for the issue? I've checked the pressure in all of the tires (including the spare). Even if it was low pressure in a tire I would think the message would indicate that it was low pressure and which tire.

Thanks in advance!

SOLVED! Sort of...

Well the problem has been fixed. I'm not sure how it came to be nor why my "fix" fixed it.

I think (but can't say with 100% certainty) that this issue happened right after I made some configuration changes with my IID tool.

Today I figured a good first step would be to check the fuses. I pulled fuses #6 and #16 and both were fine. I then start my car to run some errands and the fault is gone!

Somehow, just pulling the fuse and replacing it with the ignition off fixed the issue! I do have some more config changes soon so I'll keep an eye peeled to see if I have the same issue and if pulling a fuse works (and which specific fuse).

Thanks,
