new to this what is the forum
The vehicle forums are broken down by vehicle generation 1st 2nd or 3rd then depending on generation, which engine and engine or non engine related
so if you had a third generation truck with the 5. 9 it would go in the 3rd gen 5. 9 section since this is not engine realted it would go in 3rd Generation Ram Forum (NO engine/transmission discussions)
same for 2nd gen vehicles
Just go to the main forum page TDR Roundtable - Powered by vBulletin and scroll down till you get where you need to go they are labeled pretty well

TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold tire inflation placard pressure. The placard pressure is defined on the Tire and Loading Information label. The Tire and Loading Information label is located on the drivers side B-pillar. Vehicles equipped to be operated in either the “max load inflation pressure” condition described on the Tire and Loading Information label or the alternative “light load inflation pressure” condition described on the Supplemental Tire Pressure Information label, may also be equipped with a reset switch to choose the appropriate TPMS low pressure warning threshold levels based upon the vehicle load condition. The Supplemental Tire Pressure Information label is located on the rear face of the driver door. Operation of the “Light Load” reset switch is described later in this manual section. The tire pressure will vary with temperature by proximately 1 psi (6. 9 kPa) for every 12°F (6. 5°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure. This is defined as the tire pressure after a vehicle has not been driven for more than 3 hours, or driven less than 1 mile (1km/h) after a 3 hour period. Refer to the “Tires – General Information” in this section for information on how to properly inflate the vehicle’s tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure.
The TPM System will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low temperature effects, or natural pressure loss through the tire.
The TPM System will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recommended cold placard pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold placard pressure in order for the TPMS warning lamp to be turned off. The system will automatically update and the TPMS warning lamp will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) to receive this information.
As an example, assume your vehicle has a recommended cold tire inflation placard pressure (parked for more than 3 hours) of 35 psi (241 kPa). If the ambient temperature is 68_F (20_C) and the measured tire pressure is 30 psi (207 kPa), a temperature drop to 20_F (-7_C) will decrease the tire pressure to approximately 26 psi (179 kPa). This tire pressure is sufficiently low enough to turn ON the Tire Pressure Monitoring lamp. Driving the vehicle may cause the tire pressure to rise to approximately 30 psi (207 kPa), but the Tire Pressure Monitoring lamp will still be ON. In this situation, the Tire Pressure Monitoring lamp will turn OFF only after the tires have been inflated to the vehicle’s recommended cold tire placard pressure value.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use aftermarket tire sealants or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Monitoring Sensor.
NOTE:
² The TPMS is not intended to replace normal tire care and maintenance, nor to provide warning of a tire failure or condition.
² The TPMS should not be used as a tire pressure gauge while adjusting your tire pressure.
² Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and
stopping ability.
² The TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the “Tire Pressure Monitoring Telltale Light. ”
² Seasonal temperature changes will affect tire pressure, and the TPM system will monitor the actual tire pressure in the tire.
Tire Pressure Monitor System (TPMS) “Light Load” Reset Switch Description – If Equipped
WARNING!
Never operate your vehicle with the TPMS and tire pressures set to the Light Load Inflation Pressure settings if carrying more than two occupants (150 lbs each) plus 200 pounds of cargo. The vehicle “Light Load Definition” is found in the Supplemental Tire Pressure Information Label which is located on the rear face of the driver door. Failure to do so may cause you to lose control resulting in an accident, causing serious or fatal injury.
The Tire Pressure Monitor (TPM) system “Light Load” reset switch will allow the driver to switch between the max load inflation pressure (cold) low pressure warning threshold and the light load inflation pressure (cold) low pressure warning threshold depending on the vehicle’s load condition. The Tire and Loading Information label defines the recommended front and rear cold tire inflation pressures for the vehicle when operating in the Max Load condition. A Supplemental Tire Pressure Information label is also available defining Light Load tire inflation pressures when operating in the Light Load condition. When the “Light Load” reset switch LED is ON, the Tire Pressure Monitoring (TPM) system is using the light load inflation pressure (cold) low inflation warning thresholds and will warn the driver if one or more of the tire pressures are 25% or more below the vehicle’s defined light load inflation pressures.
“Light Load” Reset Switch Operation – If Equipped
² This vehicle may have different recommended tire pressure values between the front and rear tires as shown in both the Tire Loading Information Label and the Supplemental Tire Pressure Information Label (located on the rear face of the driver door). It is also equipped to be driven with tire pressures appropriate to either a Light Load condition or the vehicle Max Load condition.
² The “Light Load” reset switch will allow the driver to change between the max load inflation pressure (cold) low pressure warning threshold and the light load inflation pressure (cold) low pressure warning threshold depending on the vehicle’s load condition. Refer to the “Supplemental Tire Pressure Information” label for the vehicle’s Light Load inflation pressures and “Tire and Loading Information ” label for the vehicle’s Max Load inflation pressures.
² The TPMS system will always reset to the max load inflation pressure (cold) low pressure warning threshold condition when the system experiences a loss of electrical power. For example, by momentarily disconnecting the battery or IOD fuse. To switch from the max load inflation pressure (cold) low pressure warning threshold to the light load inflation pressure (cold) low pressure warning threshold, the driver must first lower all four road tire pressures to the Light Load Inflation Pressure values as listed on the Supplemental Tire Pressure Information label. The Supplemental Tire Pressure Information label is located on the rear face of the driver door. Use an accurate tire gauge to check the tire pressures when lowering all four tire pressures. Next proceed to turning the ignition on to the Run position. This may cause the TPMS low pressure warning telltale lamp located in the Instrument Cluster to turn ON and a chime to sound since the tire pressures have been lowered below the max load inflation pressure (cold) pressures. After all four tire pressures have been lowered to the Light Load inflation pressures, press the “Light Load” reset switch. If the “Light Load” switch amber colored LED turns ON, the TPM system low pressure telltale lamp will illuminate at a tire pressure 25% or more below the light load inflation pressure (cold) tire pressure values. The light load inflation pressure (cold) tire pressure values are defined in the Supplemental Tire Pressure Information label located on the rear face of the driver door. If the switch LED did not turn ON, you may need to drive the vehicle for one minute above 15 mph (25 km/h) and then press the “Light Load” reset switch again. Also, the TPM system low pressure telltale lamp will turn off once the vehicle has been driven for up to one minute above 15 mph (25 km/h). The TPM system will now remain in the Light Load vehicle pressure monitoring condition and the “Light Load” reset switch LED will remain ON for each subsequent key cycle, unless the system experiences a loss of electrical power as previously described. If the “Light Load” reset switch amber colored LED flashes on and off for 10 seconds, after all four tire pressures have been lowered to the Light Load inflation pressures, the pressure in any one of the four tires may not be at the light load inflation pressure (cold) values as indicated for the Light Load condition as defined in the Supplemental Tire Pressure Information label located on the rear face of the driver door. Using an accurate tire pressure gauge, re-check the tire pressures for the light load inflation pressure (cold) value and drive the vehicle for up to one minute above 15 mph (25 km/h) and press the “Light Load” reset switch again.

Part 2
WARNING!
It is the driver’s responsibility to change to the max load inflation pressure (cold) low pressure warning
threshold condition when not driving in the light load condition as defined as two occupants (150 lbs each) plus 200 pounds of cargo. The vehicle “Light Load Definition” is found in the Supplemental Tire Pressure Information Label located on the rear face of the driver door. Failure to do so may cause you to lose control resulting in an accident, causing serious or fatal injury. To switch back to the max load inflation pressure (cold) low pressure warning threshold, press the “Light Load” reset switch. It is not necessary to first fill the tires to the max load inflation pressure (cold) values to switch the TPMS system to the max load inflation pressure (cold) low pressure warning threshold. If after pressing the “Light Load” reset switch and tire pressures are below the max load inflation pressure (cold) low pressure warning thresholds, the TPMS low pressure warning telltale lamp located in the Instrument Cluster will turn ON and a chime will sound. The tire pressures are now required to be inflated to the max load inflation pressure (cold) values described on the Tire and Loading Information label. The Tire and Loading Information label is located on the drivers side B-pillar. If the “Light Load” reset switch LED turns OFF the TPMS has been reset and the low pressure telltale lamp will illuminate at tire pressures 25% or more below the max load inflation pressure (cold) values.
Tire Pressure Monitor System Components
The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor 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 your tires regularly and to maintain the proper pressure.
The Tire Pressure Monitoring System (TPMS) consists of the following components:
² Receiver Module
² 4 Wheel Sensors
² 2 Trigger Modules (mounted in the front wheel-wells)
² “Light Load” Reset Switch (located in the instrument panel)
² Tire Pressure Monitoring Telltale Lamp
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Lamp will illuminate in the instrument cluster, and an audible chime will be activated when one or more of the four active road tire pressures are low. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle and inflate each tire to the vehicle’s recommended cold placard pressure value. The system will automatically update and the Tire Pressure Monitoring Lamp will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Warning Light located in the Instrument Cluster will flash on and off for 75 seconds and will remain on solid when a system fault is detected. The system fault will also sound a chime. If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. A system fault can occur by any of the following scenarios:
1. Signal interference due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM sensors.
2. Installing aftermarket window tinting that affects radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
6. Loss of communication with the trigger modules or tire pressure monitoring sensors.
NOTE: Your vehicle is equipped with a non-matching full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not monitor the tire pressure in the spare tire.
2. If you install the full size spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound and the TPM Telltale Light will still turn ON due to the low tire.
3. However, after driving the vehicle for up to 10 minutes above 15 mph (25 km/h), the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will sound and the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the full size spare tire, the TPMS will update automatically and the TPM Telltale Light will turn OFF, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information.
