Hello! Bought this Jeep in 2016 with the TPMS light on. Since this is a Laredo it has the basic TPMS system. After the car is started the light and the chime comes on after a few seconds. None of the wheels had sensors in them when I bought it, only the full size spare. Bought 4 new original sensors in the fall of 2016 and had them mounted. But the light stayed on! The year after I had a new sensor mounted in the spare, but the light still stayed on. A few days ago someone told me that I should mount the spare on the car and drive with it to "wake" up the spare. Did it today, but the light is still on. How does the system recognize the spare tire since it's not moving? Checked that I have 33 psi in all 5 tires. Since I live in northern Norway my local dealer does not have any experience with this problem, and does not know how to search for a fault or fix it. Is there a scan tool available that will show DTC's stored in the WCM (wireless control module)?
