Title (customer effect)
Volvo Chassis - Diagnostic Trouble Code ( DTC ) P2459 Lighting The Malfunction
Indicator Lamp ( MIL ); Possible Frequent Regeneration Requests - OBD15 And
US14+OBD16 (Non-Common Rail) Chassis
Cause
OBD15 And US14+OBD16 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 US14+OBD16 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 And US14+OBD16 Chassis:
- Software improvements have been released to address these codes. If one or both
codes are present and there are no other symptoms to indicate a physical issue,
software should be checked and updated as necessary.
• Updated software for OBD15 chassis will have a Main Software
(MSW) 23167877 or newer
• Updated software for US14+OBD2016 chassis will have a Main
Software (MSW) 23169815 or newer
- In some cases, containment software may have been loaded to the chassis with
special instructions provided to the driver.
- For chassis that have older MSW part numbers than listed above, including
chassis with containment previously loaded:
A. Reprogram the following modules in the order listed.
1. Engine Control Module ( EMS )
2. Aftertreatment Control Module ( ACM )
B. Reset the soot load, clear DTCs and run a regeneration if P24A4 or
P10FE were present before programming the vehicle.
- If the chassis returns for frequent recurrence of the code following the software
update, normal Guided Diagnostic procedures will need to be followed.
