J1939 Code and Description CDL Code and Description Comments
3484-5
Aftertreatment #1 Ignition : Current Below Normal 2465-5
Aftertreatment #1 Ignition Transformer Primary : Current Below Normal The current flow through the primary ignition circuit is below the threshold. A snapshot is triggered. If a regeneration is in progress, the ARD completes the regeneration.
3484-6
Aftertreatment #1 Ignition : Current Above Normal 2465-6
Aftertreatment #1 Ignition Transformer Primary : Current Above Normal The current flow through the primary ignition circuit is above the threshold. A snapshot is triggered. If a regeneration is in progress, the ARD completes the regeneration.
4265-5
Aftertreatment #1 Transformer Secondary Output : Current Below Normal 3180-5
Aftertreatment #1 Ignition Transformer Secondary : Current Below Normal The ARD has attempted to ignite three times. All of the attempts were unsuccessful. The ECM has detected a problem with the current flow through the secondary circuit. The primary circuit is OK.
The spark plug is fouled.
or
There is a problem with the ignition wire between the ignition coil and the spark plug. These problems usually occur because the ignition wire has been damaged by excessive heat or improper routing.
or
The ignition coil has a problem.

Troubleshooting Test Steps Values Results
1. Determine the Code
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Use the "Aftertreatment #1 Ignition Transformer Primary Override" on Cat ET to turn on the ARD ignition system. The ARD ignition system must operate for 20 seconds in order for a diagnostic trouble code to become active. securely.
C. Determine the diagnostic code that is present.
Code
Result: A 2465-5 or 3484-5 code is present.
Proceed to Test Step 5.
Result: A 3180-5 or 4265-5 code is present.
Proceed to Test Step 2.
Result: A 2465–6 or 3484–6 code is present.
Proceed to Test Step 6.
2. Inspect the Ignition Wire
A. Visually inspect the ignition wire between the ignition coil and the ARD combustion head. Look for the following problems:
Loose connections or damaged connectors
Moisture on the connectors or the ignition wire
Damage to the ignition wire that is caused by excessive heat
Damage to the ignition wire that is caused by chafing
Improper routing of the ignition wire
Damaged insulation on the ignition wire
B. Push the boot on each end of the ignition wire. This tests whether the clip inside the boot is connected to the spark plug and to the ignition coil. There should be a "click" when you push the boot onto either part. If you felt a "click", the clip inside the boot was not previously connected.
Damaged Wire
Result: The ignition wire is not damaged.
Proceed to Test Step 3.
Result: The ignition wire is damaged.
Repair: Replace the ignition wire.
Proceed to Test Step 8.

3. Check for Spark at the Coil Output, Using the Spark Indicator
A. Assemble the 373-4609 Spark Tester as shown in Illustration 1.
Ensure that the alligator clip is secured to a good ground source.
B. Install the spark indicator as shown in illustration 2.
C. Use the "Aftertreatment #1 Ignition Transformer Primary Override" on Cat ET to turn ON the ARD ignition system. Check for spark in the spark indicator.
Spark
Result: Spark is present in the indicator.
Proceed to Test Step 4.
Result: Spark is not present in the indicator.
Repair: Replace the ignition coil. Inspect the connector terminals. If terminal damage/erosion is found, repair the ground from the coil housing to the chassis. Also, inspect the ground wire from the coil to the ARD head.
Proceed to Test Step 8.

4. Check for Spark to the Spark Plug
A. Assemble the 373-4609 Spark Tester as shown in Illustration 3.
B. Install the spark plug indicator between the spark plug and the end of the spark plug wire.
C. Use the "Aftertreatment #1 Ignition Transformer Primary Override" on Cat ET to turn ON the ARD ignition system. Check for spark in the spark indicator.
Spark
Result: Spark is present in the indicator.
Repair: Replace the spark plug.
Proceed to Test Step 8.
Result: Spark is not present in the indicator.
Repair: Replace the ignition wire.
Proceed to Test Step 8.
