| Post subject: | Check TPM System.....again |
This happened to me before, but it went away on its own. I was driving to work today and heard a ding. Dashboard had the tire light on and the overhead said "Check TPM System" Now before you all tell me I have low tire pressure, let me just say that when you have a low tire it says "Tire Pressure Low", not the message I'm seeing. I took a look at all the stems, they seem undamaged, nothing particularly out of the ordinary. If it comes on again when I leave work I'll make an appointment at the stealership, but I was just curious if anybody else had seen that before. Some background information that might be helpful: I have 245/75R16 MT/Rs on factory renegade rims (they've been there a couple months, though). It's the first real snowstorm of the year, and on my drive to work it went from rain to snow, so it was maybe a 10-15 degree temperature change over an hours drive. |

I think it will do this if one of the transmitters isnt detected for one reason or another, maybe you have one going bad? |

Just curious......Did it do it when you first changed tire size? I have a car that will do it every winter when I put on snow tires and they are the same size os OME. |

I got this from http://www.wjjeeps.com/tpms.htm. Im not sure if it will work for you or not but try this: The following test can be used to verify two functions. One, that the tire pressure sensors are transmitting properly and two, the EVIC module is receiving these transmissions accordingly. Using the STEP button on the overhead console, scroll to the blank display, then press the RESET button for five seconds, a beep will sound indicating the start of this test. The vehicle icon and transmission counters will now be displayed, (same display as individual tire pressure except counters replace tire pressure values). Upon entering the test mode, the EVIC will clear the sensor counter and each time a sensor signal for a road tire is received, the EVIC will update the counter value. The vehicle must be driven to 20-25 mph to initially activate the transmitters, and once activated they will stay activated for 15 minutes after the vehicle stops moving. The counter values should all increment somewhat evenly. If any of the road tires indicate a much different value than another tire sensor, this is a sign of a problem. Replace the appropriate tire sensor and retest the system. This test will continue until any of the overhead console buttons are pressed or the ignition is turned off. |

I occassionally have a sensor that will check out on vacation for an hour or sometimes a day and a half. They seem to return to normal always though and it is not always the same one. |
