The connector filters are located in the manifold for the lines to the ARD head. (13) Location of the connector filters on C15 applications (14) Location of the connector filters on certain C13 applicationsResults:
The filters were replaced. - Proceed to Test Step 8.Test Step 8. Perform the ARD Fuel Nozzle Heater Cycle Override
Perform the ARD fuel nozzle heater cycle by selecting the following menus on Cat ET:
"Diagnostics"
"Diagnostic Tests"
"System Troubleshooting Settings"
"ARD Fuel Nozzle Heater Cycle"
Run the ARD fuel nozzle heater cycle for 1 hour.Results:
Heater cycle is completed - Proceed to Test Step 9.Test Step 9. Perform an ARD Ignition Test
Activate the ARD Ignition Test. The test runs for approximately 5 minutes. Refer to System Operation and Testing and Adjusting , "ARD Fuel System - Test".Results:
The test is successful. - Proceed to Test Step 10.
The test is not successful. - Repair: Contact your local Caterpillar Technical Communicator for further assistance. Attach the data log to the warranty report in SIMSI.STOPTest Step 10. Data Log a Stationary Regeneration
Clear all active diagnostic and active event codes before starting the regeneration.
Data log a stationary regeneration.

Parameter     Target Conditions     Action    
DPF #1 Intake Temperature     Target is
583° C (1083° F), in cold conditions some CRS housings may not achieve the full
583° C (1083° F). Temperatures greater than
551° C (1025° F) should occur in all climates     Low Temperature: Refer to Troubleshooting Guide, "ARD Temperature Is Low"
High Temperature: Cat ET will return fault code. Troubleshoot code. No interpretation necessary.    
DPF #1 Outlet Temperature     Outlet temperature will lag inlet temperature during the warm-up period. DPF outlet should be 40° F of inlet by end of the
583° C (1083° F) hold.     Low Temperature: Refer to Troubleshooting Guide, "Diesel Particulate Filter Temperature Is Low"
High Temperature: Refer to Troubleshooting Guide, "Diesel Particulate Filter Temperature Is High"    
ARD Pilot Fuel Pressure     When ARD Fuel Pressure Control Command Percentage is 55% or greater, pilot pressure should be in range of
1475 kPa (214 psi) to
1975 kPa (288 psi)     Low Pressure: Refer to Troubleshooting Guide, "Fuel System Pressure - Test"
High Pressure: Refer to Troubleshooting Guide, "ARD Fuel Pressure Is High"    
ARD Fuel Pressure     The amount of ARD Fuel Pressure required to achieve the desired DPF Intake Temperature is a function of Engine bore size, exhaust piping, DPF configuration, and environmental conditions such as temperature and altitude.
A typical C15 at standard conditions will range in ARD Fuel pressure from
65
