WIPER-ROD 3E4164 - Caterpillar

Use this procedure if a fault is suspected with the ARD ignition system. Also use this procedure to troubleshoot the following codes:
Table 1
Diagnostic Trouble Codes for the Ignition System for the Aftertreatment Regeneration Device (ARD)
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
3484-5 2465-5 Aftertreatment #1 Ignition : Current Below Normal The Electronic Control Module (ECM) detects the following conditions:
The current flow through the primary ignition circuit is below the threshold while the ECM is trying to spark the plug.
The ECM has been powered for at least 2 seconds.
If equipped, the warning lamp will come on. The ECM will log the diagnostic code.
If a DPF regeneration is in progress, the ARD completes the regeneration.
3484-6 2465-6 Aftertreatment #1 Ignition : Current Above Normal The ECM detects the following conditions:
There is excessive current flow through the secondary ignition circuit or there is excessive current flow through the primary ignition circuit.
The ECM has been powered for at least 2 seconds.
If equipped, the warning lamp will come on. The ECM will log the diagnostic code.
4265-5 3180-5 Aftertreatment #1 Transformer Secondary Output : Current Below Normal The ECM detects the following conditions:
The ARD has attempted to ignite three times. All the attempts were unsuccessful. There is a fault with the current flow through the secondary circuit. The primary circuit is OK.
The ECM has been powered for at least 2 seconds.
If equipped, the warning lamp will come on. The ECM will log the diagnostic code.
4265-6 3180-6 Aftertreatment #1 Transformer Secondary Output : Current Above Normal The ECM detects the following conditions:
The ARD has attempted to ignite three times. All the attempts were unsuccessful. The ECM has detected a fault with the current flow through the secondary circuit. The primary circuit is OK.
The ECM has been powered for at least 2 seconds.
If equipped, the warning lamp will come on. The ECM will log the diagnostic code.
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.

The secondary circuit is between the ignition coil and the ARD combustion head. The current flow through the primary circuit indicates the condition of the primary circuit and of the secondary circuit. The ECM monitors the current flow through the primary circuit. In this way, the ECM is able to detect faults in the primary
