Service tire system keeps coming on - 2004 Chrysler Pacifica

This is usually caused when one tire is several pound lower that the others but not flat, especially if you system includes the spare tire which is easy to forget to check.

If the BCM detects a low tire pressure condition, a variation in pressure between 2*tires on the same axle, or a malfunction in the system, it will send a serial data message to the instrument cluster. Hope this helps!

that is the tire pressure monitoring system warning light, letting you know that one or more of your tire pressures is lower than spec. Some people have the light come on after service to wheels/tires. Damage to TPMS sensors is common when removing tires from wheels.

sound like two problems service tire light and check engine light.have vechicle code scan and put air in all four tires make sure put correct amount air pressure in all four tires.

one of your wheels needs air

if the pressures are ok, and the reset procedure does not fix it, it is likely that one of the sensors became damaged during the tire change. you should return to the service center that changed the tires and have them check it out.

before that, check that ALL FOUR of your tires are set to 35 psi. the system works on pressure differentials (not just low pressure) so make sure ALL the tires are set equally. also note that some systems may also have a sensor in the spare tire, and can cause the light to come on also. please check the door tag on your van to confirm what the pressures are supposed to be set at. good luck!

The service tire monitor warning can come on for many reasons. A sensor may have gone bad, may have been broken if a tire was changed recently, the car needs an updated module and antenna. The system woiuld need to be looked at by a technician.

first check tire pressure. if ok then calibrate t.p. sensors with weight you have on spare in trunk. if still happens after that you have a faulty tire pressure sensor.

try disconnecting the battery for 15-20 minutes then check again/ Please rate my response thank you very much

I had the same problem...but I found out that the dealer had rotated incorrectly the tires.
Front and back are different sizes and if a rotation is performent front to rear, you may get a stability light warning.

I corrected my tires and the warning went a way.
