High Line: vehicles with high line systems display the location of the specific underinflated tire as well as the tire pressure for all tires.
Low Line: vehicles with low line systems will not indicate the location of the underinflated wheel tire, and usually only display the TPMS warning light indicating the one or more of the tires is underinflated by 25%.
When programming an CDWTPS-Sensor for my vehicle, the tool displays a “multi-sensor” error message.
