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.

This vehicle is equipped with electronically locking front
and rear differentials. These differentials, when engaged,
mechanically lock together the axle shafts forcing the
wheels to spin at an equal rate. This allows the vehicle to
maintain its momentum and prevents it from becoming stuck. The lock
