Diesel Particulate Filters (DPF) are not applicable to all engines. A Diesel Particulate Filter should typically not be applied to engines that are not regulated. Diesel Particulate Filters are meant for usage on only diesel engines. This technology does not apply to gas engines. Consult with Caterpillar in order to determine if a Diesel Particulate Filter can be used on your engine.
Thank you for choosing the Caterpillar DPF diagnostic module (DPFdm). The DPFdm is a device designed to continuously monitor the Caterpillar DPF system. The DPFdm provides critical information to the vehicle operator and maintenance staff relative to operation and performance of the Diesel Particulate Filter.
Note: Special Instruction, REHS5606 contains the general guidelines for proper installation of the DPFdm and operational instructions.
Read each section carefully before installing and operating your DPFdm.
The information provided in this manual is general in nature, if you have questions for your specific installation, contact Caterpillar or your Caterpillar dealer.
Note: Federal and CARB verifications require that every vehicle fitted with a Diesel Particulate Filter must install and operate a backpressure monitoring device such as the DPFdm. Contact Caterpillar or your Caterpillar dealer if you have questions regarding your specific requirements.

The DPFdm monitors exhaust temperature and backpressure of the DPF system. The DPFdm will warn the operator of the need for filter cleaning or if a potential exhaust system problem exists. The DPFdm is equipped with internal memory and records temperature, backpressure, and alarm events that occur during vehicle operation. Data are accumulated over time and can be downloaded via a serial link to a PC for further analysis. The DPFdm contains alarm outputs which activate lights on a remote display. Contact with your Caterpillar dealer for complete details.
The DPFdm is ruggedly packaged and capable of withstanding a wide temperature range. It is designed for retrofit into off-road machines.
Exhaust temperature is monitored with a thermocouple probe installed in the DPF inlet section. Exhaust backpressure is measured with a pressure sensor located within the DPFdm and connected to the DPF inlet using an extension tube. The temperature and pressure data are collected on a continuous basis and monitored to detect conditions that exceed defined limits.

DPFdm Backup Battery
The DPFdm contains a backup battery that retains critical parameters in the event of a power loss to the DPFdm. The DPFdm will not operate on this battery if power is lost to the DPFdm. The battery retains stored data, alarm settings, and date/time.
The battery must be replaced every 5 years. Contact your Caterpillar dealer to replace the battery. The procedure requires the use of the DPFdm Communications Software and the ability to apply low pressure to the DPFdm. If you do not have the software or the ability to apply
DPFdm Communications Software
If your shop is equipped with a mobile PC or laptop computer running Windows 95 or newer, you will be able to access the data the DPFdm stores in memory.
The DPFdm software is a user friendly single screen program that operates under the Windows 95, 98, 2000, and XP operating systems. Once installed on a PC, the software allows communication between the PC and the DPFdm. You can develop DPFdm alarm programs, download data, graph the data, and diagnose DPFdm alarms. It is available on CD format and includes DPFdm Communications Manual, software CD, and interface cable that allows communications between the PC and the DPFdm.
Updates are also available via the internet at http://126.96.36.199:8080/. Here you will find the latest updates for the DPFdm Communications Software and the latest firmware. Contact your Caterpillar dealer for a user name and password.
This is a valuable tool that will aid in the diagnosis of DPFdm alarm events. With this software you will be able to determine time/date of an alarm, the back pressure and temperature at the time of the alarm, and what caused the alarm.
The DPFdm installation should be conducted in two parts: mechanical and electrical. Both sections of the installation are included in this manual.
Note: The following DPFdm installation conditions must be met or the warranty may be voided:
- The DPFdm must be mounted in a space where the ambient temperature is below
85 °C (185 °F)under normal vehicle operation. The DPFdm must be located away from direct sources of heat such as the engine, exhaust manifolds, and radiator.
- The DPFdm must be mounted in a location where it is not directly exposed to high-pressure steam cleaning, solvents, battery off-gas, or electrical discharge.
- The DPFdm must be connected to a 12 VDC or 24 VDC power supply.
- The DPFdm must not be subjected to voltage supply or power surges greater than 30 VDC.
- The thermocouple and wire supplied with the DPFdm must be used with this unit. Use of any other thermocouple or wire must be approved by your Caterpillar dealer.
Caterpillar recommends that the DPFdm be mounted in a position higher than the DPF inlet. This will reduce clogging of the pressure sensor from water that collects in the tubing between the DPF system and the pressure sensor.
- Park the vehicle on a level surface, apply parking brake, and follow all safety precautions as prescribed by shop policy.
- Disconnect the batteries or turn off the master battery disconnect switch.
- Select a location for the DPFdm that meets the above criteria. Use the four mounting holes on the DPFdm as a template to mark four points and drill four 9/32 inch holes. Attach the DPFdm using the self-tapping screws and washers supplied in the DPFdm Kit.
- Every DPF is fitted with a 1/4 inch female NPT boss (Illustration 4), that will accept the fittings identified in the DPFdm installation kit. Before any fittings are installed on the DPF system, the location of the boss must be accessible so that the thermocouple can be easily inserted into the Tee fitting. If the boss is not accessible, the DPF inlet head should be rotated until the boss is accessible.

Illustration 7 g01427849
- Loop the tubing at least once when running the tubing from the DPF system to the DPFdm. All
6.1 ± 0.5 m (20 ± 1.5 ft)of the tubing must be used. If the distance between the DPF system and the DPFdm is less than 6.1 m (20 ft), the excess tubing should be looped and mounted in the vehicle.
- Thread the female connector to the pressure sensor on the DPFdm with a 3/4 inch wrench. Insert the copper tube into the fitting. Tighten the lock nut on the fitting until the fitting is finger tight. Then tighten the fitting 1-1/4 turns with a 9/16 inch wrench.
6.1 ± 0.5 m (20 ± 1.5 ft)of the tubing must be used or the DPFdm warranty may be void.
The standard DPFdm is a sealed unit with three external pigtails (refer to Illustration 3 and 15). The male Weather-Pack connector is for 12 VDC or 24 VDC power supply to the DPFdm. The female Weather-Pack connector bundled with the female thermocouple connector marked "INLET" is used for the alarm outputs and the inlet temperature. This thermocouple connector is always used.
The Female Thermocouple connector alone marked "OUTLET" is a secondary temperature input and is only used when using two thermocouples.
Note: When using only one thermocouple, the thermocouple must be plugged into the connector labeled "INLET" or else the DPFdm will alarm.
The standard installation kit contains the minimum required wiring for completing the necessary DPFdm electrical connections. The following instructions are for the standard DPFdm installation kit.
Specialized connectors and wiring harnesses may be available from your Caterpillar dealer.
Note: All wiring should be run in such a way that the wiring is not in contact with heat sources such as the engine, exhaust manifolds and radiators. Protective wire loom supplied with the DPFdm installation kit should be used to cover the wiring. The wire loom can be secured in the vehicle with tie wrap or other fastening devices.
- Locate a 12 V or 24 V power supply that is always available even when the key is turned off.
- Run the red wire from the positive side of the power supply to the DPFdm. Caterpillar recommends that a 3 amp automotive type fuse be installed between the power supply and the DPFdm.
- Run the white wire from either the negative side of the power supply, or any other ground connection, to the DPFdm.
- Insert the power wires in wire loom to protect the wires.
- Refer to "Proper Wiring Connections" for the Weather-Pack crimping procedure.

DPFdm Display LED
|Status LEDs and information|
|System Status||Will blink once every 2 seconds indicating adequate power supply and normal operation.|
|Over-Pressure Alarm||ON if back pressure exceeds set limits / OFF during normal operation|
|Over-Temperature Alarm||ON if exhaust temperature exceeds set limit / OFF during normal operation|
|System Problem||ON if the DPFdm detects a problem with a sensor / OFF during normal operation|
Basic DPFdm Alarm Diagnosis
In the event of an alarm one or both of the lamps in the remote display module will illuminate. In addition, lamps in the DPFdm will also illuminate.
The yellow lamp in the Remote Display Module can indicate one or more of the following alarms:
- Over-Temperature - High exhaust temperature was detected
- Over-Pressure Warning - Back pressure is high
- Temperature Probe Failure - Probe has either shorted or the circuit is open
- Pressure Failure: The pressure tubing is broken or cracked, water has accumulated in the pressure tubing, or the pressure sensor needs attention.
- DPFdm Power failure: If the DPFdm fails and power is still connected, the yellow lamp illuminates in the RDM.
The Red lamp in the Remote Display Module only indicates when the back pressure is exceeding engine manufacturer's specifications. The engine must be shut down whenever it is safe to do so to prevent damage to the engine or DPF system.
In the event a lamp illuminates in the RDM consult Table 2 for very basic DPFdm alarm analysis. It is not intended to be used to determine the cause of a DPFdm alarm. The DPFdm Communications Software must be used in conjunction with the LEDs to diagnose a DPFdm alarm. If you do not have the DPFdm Communications Software you must contact your Caterpillar dealer to assist in diagnosing DPFdm alarms.
