use an obd2 scanning tool to solve car problems

by King Zhu assistant Q:Headlight Auto Leveling Sensor Issue? For the past few days, I've had this read triangle indication come On and go Off at times. In reading through the forums, I gather that it is due to a faulty Headlight Auto Leveling Sensor that is installed in the rear Driver side wheel well. Attached here is a picture of the indicator. Can someone please confirm my finding?

A:The level sensor for cars with HID lights is actually connected to the rear axle on the drivers side. As the body/axle relationship changes it tells the car to adjust the reflectors inside the HID headlights. Get under the rear axles and look for broken parts, unhooked or broken wires. The only level sensors I've seen go bad are cars from "rust belt" areas where they salt the roads. You should also scan the car for specific error codes with an obd2 diagnostic tool.

Q:Blinking air pressure light? Hi guys im new here, I own a 07 prius and I have an issue. In the past my air pressure sensor has come on multiple times but usually when I put air in the tires it goes away. This time the sensor comes on, blinks for about 10-20 seconds and stays on solid. Ive checked all my tires plus the spare and they are all ok. Any suggestions on what could be the problem? One of my tires has a fixaflat plug in that seems to leak every few days so im gonna fix that and see if that might be the issue. Im out of warranty so im trying not to take it to the stealership for something minor like this. Any help is appreciated!

A:You can also, for much less $ than the dealer charges, call around to your local tire shops. Almost all of them have the necessary obd2 scanning tools nowadays, as the TPMS (Tire Pressure Monitoring System) was made standard in vehicles a few years back.

I assume you've already read the owners manual and tried to reset the light with the button under the steering wheel? If that doesn't work, my money is on the sensors in the wheels themselves. If those sensors are original, the batteries inside the sensors are 6 years old now and they usually only last 4-7 years on average anyways. The tire shop charged me $50 per tire installed and programmed, when my sensors went bad. The dealer wanted double that amount.
