TPMS and drive-thrus

[TouchdownTennessee]

Here's an odd occurrence I have noticed: When I go through the drive-thru at Arby's in my area, the TPMS light comes on! This has happened at two different locations. I noticed the indicator was on while waiting in line after ordering. I pulled into a space after getting my order and checked the tires. The pressure was fine in all. It occurred again the next time I went through that same location and finally this past week at a different location. This has not happened at any other restaurant drive-thrus.

The TPMS indicator goes off after I turn the car off and back on.

Just something to watch for. It must be the frequency that Arby's uses for their ordering system.

You're exactly right. Certain radio frequencies cause this sensor to register a false reading. I have an aftermarket HID kit that does the same thing. I'm going to eventually wrap my ballasts in something that blocks the radio waves.
