Title (customer effect)
Volvo Chassis - Diagnostic Trouble Code ( DTC ) P2459 Lighting The Malfunction
Indicator Lamp ( MIL ); Possible Frequent Regeneration Requests - OBD15 And Newer
Chassis
Cause
OBD15 and newer chassis may log DTC P2459 - Diesel Particulate Filter Regeneration
Frequency (Bank 1). P2459 may log with or without frequent regeneration
requests. Guided Diagnostic steps may complete with No Fault Found.
Solution
Overview
OBD15 and newer chassis may log DTC P2459 during operation. The diagnostic process
that this DTC sets for is the monitor of how often regenerations are requested by the
Engine Control Module ( EMS ), and is intended to determine when the Diesel
Particulate Filter ( DPF ) needs to be serviced or indicate a problem causing rapid soot
accumulation. Chassis experiencing repeat occurrences of P2459 are most commonly
units operating in applications that involve any of the below:
- Frequent stop-and-go operation (food service deliveries, for example)
- Local operation with little to no drive time at stable highway speeds or short
overall distance traveled at one time
• Passive regeneration only occurs when exhaust temperatures are able to
reach the correct level and are sustained at that level while the chassis is in
motion. These conditions are normally only seen during highway operation.
- Operation requiring an extended amount of idling or operation at low speeds
(Paving and construction; mining)
Repair
Verify the chassis emissions level
• Details can be found in the Product Details box on the Product tab in PTT as seen
below:
For OBD15 (Commonly Year Model 2016) Chassis ONLY:
- Software improvements have been released to address this code. If
P2459 is present, software should be checked and updated as necessary.
- Two modules are affected by this update and should be reprogrammed in the
following order:
1. Engine Control Module ( EMS )
2. Aftertreatment Control Module ( ACM )
- If there are other codes and symtoms present or the code(s) continue to return
frequently following the software update, normal diagnostic procedures should be
followed to determine the issue.
For OBD16 and Newer Chassis:
- EMS Software should be verified to be current
- The DTC readout and customer complaint should be reviewed to ensure there are
no other codes in the EMS or symptoms reported that may be related to P226C
- Any accompanying codes or symptoms should be diagnosed with normal
procedures.
