What does srvc tpms mean. I bought this car last week for a cheap price. It is a 2009 and it's been to the shop twice now, is there any more problems that will come up the next time I drive it. I am getting a new radio, aftermarket, tomorrow. It's from Best Buy, and having them install it, I hope they know what they are doing.

It means service the Tire Pressure Monitoring System. This system monitors your tire pressure in each wheel. Access the system by the key fob or dash info button if not fob equipped. It will tell you which tire is low or has a problem. It is either a too low or too high tire pressure or a dead battery in the sensor. Each wheel has a sensor under the valve stem and if the battery is dead or loses communication with the monitor it sets that warning light. As for the radio be careful. The stock radio uses the car's computer to verify the VIN, and if correct, will then power on the radio. Aftermarket radios may not be able to do that. If the shop just wires the radio into a convenient hot wire the radio will be powered all the time and kill the battery. Off must be completely OFF. Ask me how I know. Also the car uses the radio speakers for warning chimes like 'key in ignition' or 'lights are on' and the directional signals 'click' sound. The module that does that with an aftermarket radio is another $100 .

Thanks, the next time I am at the shop I will tell them about the tires and the battery, they do have the tool to check and reset the sensors. as far as the radio ,I did check the receipt and it shows they have the module for the chimes on order, so I guess they know about the battery drain also, if it is not hooked up correctly.

tool to check and reset the sensors.

For what they charge to change sensors I found it easier to purchase the AUTEL TPMS tool. It will identify and report the status of each sensor. You can activate them one by one to establish their position so the TPMS monitor knows where they are. Remember, first just check your tire pressure. That is what the system is there for. Too many people were driving around on low tires and getting into crashes. Good news on the chime module- I guess that shop knows what it is doing.
