Ram 1500/2500/3500: Tire Pressure Information System (TPIS) 3500 Series Trucks

Your vehicle may be equipped with a Tire Pressure Information System (TPIS).

The Tire Pressure Information System (TPIS) uses wireless technology with wheel rim mounted electronic sensors to transmit tire pressure levels. Sensors mounted to each wheel as part of the valve stem transmit tire pressure readings to the receiver module.

NOTE: It is particularly important for you to check the tire pressure in all of the tires on your vehicle monthly and to maintain the proper pressure.

The TPIS consists of the following components:

  • Receiver module
  • Four TPM sensors (Single Rear Wheel (SRW) applications)
  • Six TPM sensors (Dual Rear Wheel (DRW) applications)
  • Pressure display in the Electronic Vehicle Information Center (EVIC)

The TPIS system will display all four (Single Rear Wheel (SRW) applications) or six (Dual Rear Wheel (DRW) applications) tire pressure values EVIC display.

If a system fault is detected, the EVIC will display a SERVICE TPM SYSTEM message for a minimum of five seconds and then display dashes (- -) in place of the pressure value to indicate which sensor is not being received.

If the ignition switch is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the SERVICE TPM SYSTEM message will no longer be displayed, and a pressure value will display in place of the dashes. A system fault can occur due to any of the following:

  • Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPM sensors.
  • Installing aftermarket window tinting that contains materials that may block radio wave signals.
  • Accumulation of snow or ice around the wheels or wheel housings.
  • Using tire chains on the vehicle.
  • Using wheels/tires not equipped with TPM sensors.
