How do I Troubleshoot the Tire Pressure Monitor on a 2004 Chevy Tahoe
If you are driving down the road in your Chevy Tahoe and you notice a light on the dash for "tire failure" or "low tire pressure" you might become alarmed. Today more and more vehicles are being manufactured with tire pressure monitor systems called TPMS. The TPMS was designed for driving safety because most people never take the time to even look at their tires or check the air pressure. Low air pressure in a tire is the leading cause of tire failure and can lead to accidents. If you have a TPMS monitor that is not working properly, you can troubleshoot it with a few easy steps.
Instructions
- 1
Walk around your Tahoe and look at each tire to see if one of them looks low.
2Slide the air pressure gauge over each valve stem to check each tire and make sure that it is inflated to the proper psi. The proper psi is noted on the car door. Never go by the maximum inflation noted on the tire. You must always go by what is indicated on the car door. Improper inflation will cause the TPMS unit to flag a problem.
3Take your TPMS computer scanner out of the box and become familiar with the settings. You will need to push the buttons on the front to find your make and model of car. Press the button to enter the scan mode and walk around to each tire. Press the button at each tire until you get an indication that the scanner cannot find the TPMS unit. This is the unit that needs to be changed.
