C13, C15, And C18 Engines ARD is Disabled

C13, C15, and C18 Engines/ ARD Is DisabledARD Is DisabledUse this procedure in order to troubleshoot a failed aftertreatment regeneration or

use this procedure if one of the following event codes are active. Refer to Troubleshooting, "Event Codes" for information about event codes. For information

on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".

Active regenerations usually occur during normal engine operation. However, engine operation or operator desire may cause the operator to activate the force

regeneration switch. This switch signals the Engine Electronic Control Module (ECM) that a forced regeneration is desired. The engine ECM will determine the status of

the engine and the products operating condition and determine if it is okay to begin an active regeneration. The elapsed time is approximately 5 seconds for the engine

ECM to determine if the conditions are acceptable for an active regeneration to begin.

If conditions allow that an active regeneration may begin, the ECM will illuminate the appropriate indicators and begin the active regeneration. If conditions will not allow an active regeneration to begin, the ECM will illuminate the Action Lamp and

annunciate one of the following Diagnostic Trouble Codes (DTCs). The code will appear on the Messenger Display. The code will also be displayed on Cat ET.

Note: One forced regeneration per key cycle is permitted if a failure to ignite, insufficient temperature to complete regeneration, or loss of combustion diagnostic

trouble code is active. This determines if the regeneration can run and clear the event.

3483-11

E1305 (1)

Initial Assembly Aftertreatment #1

Procedure Required

Initial assembly of the aftertreatment system is complete or the Engine ECM or the A5:E2

The regeneration system is disabled due to the ARD Disable Switch in the operator

interface.

E1301 (1)

Aftertreatment Regeneration Cannot Start Due To System

Fault

There is an active fault related to the ARD combustion air system, ARD fuel system, or

ARD ignition system.

3716-15

E1300 (1)

Aftertreatment Regeneration Cannot

Start Due To Low Engine Temperature

The coolant temperature is below40° C (104° F ) and the Diesel Particulate

Filter inlet temperature is below50° C (122° F).

If the ambient temperature is−15° C (5° F) or below, the coolant

temperature must be60° C (140° F) for an active regeneration to

begin.

3750-15

E1302 (1)

Aftertreatment Regeneration Cannot

Start Due To Conditions Not Met

One or more conditions are not allowing an Aftertreatment Regeneration to start, Refer to

Test Step 7.

3750-17

E1239 (2)

DPF #1 Conditions Not Met for Active

Regeneration

The operator did not allow a regeneration to occur or 25 hours has elapsed since the last successful regeneration. The operator must

respond when the DPF lamp and action lamp is illuminated. This event will trigger a 50%

derate.

3750-18

E1239 (3)


Regeneration

The operator did not allow a regeneration to occur or 32 hours has elapsed since the last successful regeneration. The operator must respond when the DPF lamp, action lamp is

illuminated and audible sound in the cab. This event will trigger a 100% derate.

3750-31

E1239 (1)


Regeneration

The operator did not allow enough time for regeneration to occur. The operator must

respond when the DPF lamp is illuminated. The operator must allow the engine to idle

until the soot load is reduced to 50 percent.

Troubleshooting Test Steps Values Results

1. Check for Diagnostic Codes that are Active

A. Establish communication between Cat ET and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.

Diagnostic code

Result: A E1239 (1), E1239 (2), E1239 (3), 3750-31, 3750-17 or 3750-18 diagnostic code is present, proceed to Test Step 2.

Result: A E993 (3) or 3703-31 diagnostic code is present, proceed to Test Step 3.

B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.

C. Check and record any event codes that are active or logged.






2. A E1239 (1), E1239 (2), E1239 (3), 3750-31, 3750-17 or 3750-18 Diagnostic Code is Present.

A. The operator did not allow a regeneration to occur or an automatic regeneration did not occur within the required time limit. The operator must respond when the DPF lamp is illuminated. Once the DPF and action lamp are illuminated, the operator must allow the engine to idle until the soot load is reduced to 50 percent.

B. Perform a "Manual DPF Regeneration" using Cat ET.

Manual DPF Regeneration

Result: The "Manual DPF Regeneration" was successful.

Return the unit to service.

Result: The "Manual DPF Regeneration" was not successful.

Troubleshoot the active diagnostic codes.

3. A E993 (3) or 3703-31 Diagnostic Code is Present.

A. The operator has disabled the regeneration system and a regeneration is necessary.

Disabled regeneration

Result: Perform a regeneration. Refer to the Operation and Maintenance Manual, "Diesel Particulate Filter Regeneration" for the proper operation of the regeneration system.


4. A E1040 (2) or 3530-31 Diagnostic Code is Present.

A. The regeneration system is disabled by Cat ET.

Regeneration disabled by Cat ET.

Result: Establish communication between Cat ET and the engine ECM. Set the value of the "Aftertreatment Regeneration Device" from "Disabled" to "Enabled".


5. Aftertreatment Regeneration Cannot Start Due To Low Engine Temperature

A. The engine temperature is too low for an aftertreatment regeneration.
