Overview
| CODE | REASON | EFFECT |
| Fault Code: 14624 PID: SPN: 517006 FMI: 1/1 LAMP: Amber SRT: |
Aftertreatment diesel exhaust fluid dosing unit filter change interval has been exceeded.
|
None on performance. |
Circuit Description
The engine control module (ECM) informs the driver of a maintenance event by using the Maintenance Monitor feature’s aftertreatment diesel exhaust fluid dosing unit filter replacement limits.
Component Location
The aftertreatment diesel exhaust fluid dosing unit filter is mounted directly to the aftertreatment diesel exhaust fluid dosing unit.
Conditions for Running the Diagnostics
This diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running.
Conditions for Setting the Fault Codes
The Engine Control Module (ECM) detected the aftertreatment diesel exhaust fluid dosing unit filter requires maintenance based on the programmable setting in the Maintenance Monitor.
Action Taken When the Fault Code is Active
- The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails.
Conditions for Clearing the Fault Code
- Use the recommended Cummins® electronic service tool or equivalent to reset the Maintenance Monitor feature.
- The ECM will turn off the flashing amber CHECK ENGINE lamp / MAINTENANCE lamp immediately after the diagnostic runs and passes.
Shop Talk
Possible causes of this fault code include:
