Robert R :

Ok first we need to determine if your vehicle is an early build vehicle or normal build because there are 2 systems that can be on your vehicle. we need the VIN number or if you can get the production date from the door sticker, we can determine if early build or late build.

sorry I messed up THIS is the VIN




Expert:  Robert R replied 5 years ago.

Ok, Yes your vehicle is definitely an Early Build vehicle. You may need to obtain a magnet to train the sensors. Then after training, the vehicle must be driven above 20 mph for 15 minutes then the light will automatically shut off. see the docs, if it is incomplete, let me know...


PS - You may have a bad sensor or a weak battery if the sensors won't train, see Doc 2 heading for non critical system alerts...

I had this car in at Tires Plus because the there was was some bad bead leaks on two of the tires and the would have to be filled evry 3-4 days becuse the low pressure sensor came on. They got that fixed and about 3 hrs and 25 miles later this "service tire system soon" light came on. I brought it back to them and they said it should gout once i drive it for a while that was yesterday and about 65 highway miles later, still is on. I asked them before i left if they needed to retrain the sensors and they no taht they were get a reading from all the tires. Does any of this infoo help? I am going to try what you sent me biut i would like to knoe your thaoughts on the info just given



Expert:  Robert R replied 5 years ago.

Seems like there is a chance that one of the sensors may be damaged, if a sensor is not transmitting, you will get the "service tire system soon" light, there is a test that you can run to check this, read all 3 Docs, there is a procedure there that should help you determine if you have a bad sensor, if you need a magnet, any strong magnet will work to activate the sensors.


PS. I need to log off for a bit, if you need more info, I will be back online in a couple of hours, thanks for your patience...Smile

I need to get a bigger magnet the one I tried did nothing
Expert:  Robert R replied 5 years ago.

Ok, I'm here if you need me...try a magnet from a speaker, round one with hole in the middle - you might need to break apart the speaker to get the magnet out though. Wink

Customer: replied 5 years ago.
I tried a bigger magnet and it worked, I got all 4 tires to honk and retrain, light still on. Now what?
Expert:  Robert R replied 5 years ago.
Did you drive the vehicle for a constant speed above 20 mph for about 15 to 20 minutes? Also make sure all tires are set at the factory recommended pressure, too low or too high pressure will cause the light to stay on. If you did that and the light still stays on you may have a bad Skim module. You might need to take it to the dealer so they can scan the system to see what else might be could still have a bad sensor transmitting the wrong pressure reading, etc...
