PID: N/A
SPN: 3512
FMI: 3

Description: 3 V Sensor Supply Bank 2 Circuit Failed High
Troubleshooting:

PID: N/A
SPN: 3556
FMI: 0

Description: Regeneration Temperature – Out of Range High
Troubleshooting:
DESCRIPTION:
This code sets when the ACM detects that the DOC outlet temperature sensor is greater than
the modeled threshold.
MONITORED PARAMETER:
Diesel Oxidation Catalyst (DOC) Temperature Outlet temperature sensor.
TYPICAL ENABLING CONDITIONS:
Aftertreatment 1 hydrocarbon dozer data valid but above normal operational range – most
severe level.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
2 seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
Derate 25%
POSSIBLE CAUSES:
1. Low temp Aftertreatment Device (ATD) regeneration needs to be performed.
2. Faulty DOC outlet temperature sensor.
3. Exhaust system leaks.
4. Faulty HC doser block.

Description: Regeneration Temperature – Out of Range Low
Troubleshooting:
DESCRIPTION:
This code sets when the exhaust temperature does not increase above the modeled threshold
when regeneration is enabled.
MONITORED PARAMETER:
Diesel Oxidation Catalyst (DOC) Outlet Temperature sensor.
TYPICAL ENABLING CONDITIONS:
Regeneration enabled, 1100 to 2050 rpm, 50% to 100% engine load.

None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
20 seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
None
VERIFICATION:
Parked regeneration
POSSIBLE CAUSES:
1. Leaks in Exhaust system.
2. Faulty Hydrocarbon (HC) doser injection valve.
3. Ports need cleaning.
4. Faulty HC doser block.
5. Faulty DOC outlet temperature sensor.
