Description: High Idle Regeneration (HIR0 Aborted – Low Coolant Temp
Troubleshooting:
DESCRIPTION:
This fault logs when the coolant temperature fails to reach 60°C (140°F) during high idle
regeneration initiation.
MONITORED PARAMETER:
Engine coolant temperature.
TYPICAL ENABLING CONDITIONS:
Always enabled
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Always enabled
TYPCIAL DURATION:
Two seconds
DASH LAMPS:
CEL
ENGINE REACTION:
None
VERIFICATION:
Parked regeneration
POSSIBLE CAUSES:
1. Faulty coolant temperature sensor.
2. Faulty engine cooling fan.
3. Faulty engine coolant thermostat.

Description: High Idle Regeneration (Aborted) – Low Regeneration Temperature
Troubleshooting:
NOTE: The fault indicates that the high idle regeneration (HIR) was aborted due to the diesel
oxidation catalyst (DOC) outlet temperature not reaching the expected target temperature to
complete a HIR. If there are any other regeneration or fuel system related faults address those
first. The CEL and MIL lamp will remain on until a fault is resolved or a successful regeneration
is completed. Retain log file if customer assistance is required.
POSSIBLE ISSUES:
1. Low fuel compensation pressure.
2. Exhaust leaks.
3. Fuel leaks.
4. Sticking hydrocarbon (HC) doser injector valve (high doser line pressure).
5. DOC outlet temperature not responding.

Description: Diesel Particulate Filter Zone 3 Condition
Troubleshooting:
NOTE: This code is informational only and used by service to help understand which dash
lights illuminated during normal service. A stationary regeneration is required if the fault code is
active. No action is required for an inactive fault code.
POSSIBLE CAUSES:
Stationary regeneration is needed.

Description: Soot Level High
Troubleshooting:
NOTE: When this code is detected, the operator has two minutes to initiate regeneration
request.
POSSIBLE CAUSES:
Parked regeneration is needed.
