Hello recently my wife took our truck to get the oul changed, when she went back to pick it up the Service Tire Monitor System light was on.

It cannot be coinisidence! However she didnt go back in and tell them so im not going back to tell them because they would never believe me.

What could they have done?

Can i reset it?

Thank You

Wrong tire pressures or not matching, basics here, get a tire gage out and check pressures to start with. If ok clear the message. Reset info is in owners manual.

Tire pressure is correct, i do not have an owners manual this was one of the reasons i asked about the reset procedure...

thanks

Did they rotate the tires?
If so you might have to do a recalibrate.
Cadillacs do this recalibrate.

Just the oil change as i stated...nothing else

You can download an owners manual here:

You can reset the TPMS yourself or pay a dealer or tire shop to do it for you.
