Title (customer effect)

Service Only Regen Requested With No Warning. Diagnostic Trouble Codes ( DTC )
P24A4 / P10FE Active Or Inactive With Several Counts - OBD15 And
US14+OBD16 (Non-Common Rail Fuel System) Chassis

Cause

OBD15 and US14+OBD16 (Commonly Year Models 2016 and 2017) Conventional
Chassis that spend most of the time in stop-and-go operation may log DTCs P24A4 and
P10FE, together or separately.

Solution

Overview
During city driving (P&D and LTL) duty cycles, the Diesel Particulate Filter
(DPF) can accumulate large amounts of soot inside. If the chassis is not driven on the
highway enough for passive regeneration to reduce soot levels, a stationary regeneration
will be required. The unit may also display “Service Only” regeneration on the Driver
Information Display ( DID ) with no prior alert to the driver, which can result in an
unplanned stop at a maintenance facility for a service regeneration can be performed.

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.
