TPMS Control Unit
Mounted over the accelerator pedal module, the TPMS control unit receives wireless tire pressure sensor ID signals every time the vehicle speeds exceeds 28 mph (45 km/h). It also receives wireless signals from the transmitters for tire pressure and the sensor condition, and it continuously monitors and controls the system. The TPMS control unit cannot directly determine the position (location) of a tire pressure sensor(s) on the vehicle since it is a wireless system. Tire pressure sensor locations will change during scheduled vehicle maintenance (tire rotation).
NOTE:
To determine the actual location of each tire pressure sensor on the vehicle, do the tire pressure sensor location procedure (see TIRE PRESSURE SENSOR LOCATION
). Once the tire pressure sensor locations are identified, write the sensor ID on the sidewall of the tire with a tire crayon to eliminate confusion.
