Diagnostic Trouble Codes for ARD Failed to Ignite    
CDL Code     Code Description     Comments    
E1025-2     Aftertreatment #1 Failed to Ignite : Level 2     The ARD has failed to ignite for a regeneration cycle or the ARD failed to ignite during an ARD Ignition Test. Usually, this code is accompanied by another logged code that indicates the condition that caused the failure to ignite.    System OperationThe combustion air system routes pressurized air from the outlet of the high-pressure turbocharger to the ARD. The combustion air is mixed with fuel inside the ARD combustion head. The air/fuel mixture is ignited and the air/fuel mixture is burned in order to increase the temperature of the exhaust gas. The high temperature exhaust gas burns off the soot in the Diesel Particulate Filter (DPF). This process is known as DPF regeneration.The ECM sends a pulse width modulated signal to the combustion air valve. The actuator in the combustion air valve regulates the combustion air to the ARD combustion head.The ECM also sends pulse width modulated signals to the pilot fuel control valve. The pilot fuel control valve regulates the amount of fuel that is injected into the ARD combustion head.The ECM controls the ARD ignition system. Whenever the ARD is required to operate, the ECM operates the ARD ignition coil which then generates high voltage pulses in the ignition cable. The high voltage pulses create sparks at the spark plug in the ARD head. The spark ignites the fuel/air mixture in the ARD.If the amount of fuel or air that enters the ARD combustion head is incorrect or there are no ignition sparks, combustion may not occur.Test Step 1. Check for Associated Diagnostic Trouble Codes
Establish communication between the electronic service tool and the engine ECM.
Table 2 lists the diagnostic codes that are associated with the "E1025-2 Aftertreatment #1 Failed to Ignite" code. Determine if any of the codes in Table 2 are present.

3180-6     Aftertreatment #1 Ignition Transformer Secondary : Current Above Normal     ARD Ignition - Test    Results:
An associated diagnostic trouble code is not present. - Proceed to Test Step 2.
An associated diagnostic trouble code is present. - Repair: Refer to Troubleshooting, "Diagnostic Trouble Codes" in order to troubleshoot the associated diagnostic code.STOPTest Step 2. Perform an ARD Ignition Test
Use the electronic service tool to perform an "ARD Ignition Test".
Determine if any of the codes in Table 2 are generated.Results:
An associated diagnostic trouble code is not present. - Proceed to Test Step 3.
An associated diagnostic trouble code is present. - Repair: Refer to Troubleshooting, "Diagnostic Trouble Codes" in order to troubleshoot the associated diagnostic code.STOPTest Step 3. Check the Current Flow to the ARD Nozzle Heater
Verify that the engine is off.

Measuring the current flow (5) ARD combustion head (6) Metal part of heater wire (7) Insulated part of heater wire
Connect a suitable clamp-ammeter around the insulated part of the heater wire (7). Make sure that the jaws of the ammeter are away from the metal part of the heater wire (6) .
Establish communication between the electronic service tool and the ECM. Refer to Troubleshooting, "Electronic Service Tools" for the proper procedure.
The ignition system may cause an electrical shock hazard, which may cause personal injury or death. Avoid contacting the ignition system components and the ignition system wiring during operation.
Start the engine. Activate the "ARD Nozzle Heater Test".
Record the current reading on the ammeter.
Disable the "ARD Nozzle Heater Test". Stop the engine. Remove the clamp-ammeter.
Disconnect the electronic service tool.Results:
The ammeter reads at least 3.5 Amps. - The current consumption is normal. Proceed to Test Step 4.
The ammeter reads less than 3.5 Amps. - Repair: Investigate the cause of the low current consumption. Refer to Troubleshooting, "ARD Nozzle Heater - Test".STOPTest Step 4. Check for Voltage at the Spark Plug

If the engine is running, the ARD spark plug will continue to fire. Turn the key to the OFF position before servicing the ARD spark plug.
Disconnect the ignition wire from the ARD spark plug.
Connect the spark indicator between the ignition wire and the ARD spark plug.
The ignition system may cause an electrical shock hazard, which may cause personal injury or
