Service Error Identifiers
Description Troubleshooting
$11B5
Aftertreatment #1 NOx Level Sensors Not
Ready
The NOx sensors have not reached the cor-
rect temperature to start reading the NOx
level.
$11B9
Aftertreatment #1 SCR Catalyst Intake Gas
Temperature Too Low
The SCR system cannot dose due to the SCR
inlet temperature not being high enough to al-
low DEF dosing to initiate. Restart the After-
treatment System Functional Test.
$11BB
Aftertreatment Diesel Exhaust Fluid Level Too
Low
The DEF tank level is too low. Fill the DEF
tank and restart the Aftertreatment System
Functional Test.
$11C0
Aftertreatment Diesel Oxidation Catalyst Intake
Temperature Too Low
The SCR system cannot dose due to the DPF
Inlet temperature not being high enough to al-
low DEF dosing to initiate. Refer to Trouble-
shooting, “Diesel Oxidation Catalyst Has
Incorrect Inlet Temperature”. Check for ex-
haust leaks and then restart the Aftertreat-
ment System Functional Test.
$11C2
Aftertreatment SCR System in Warmup Mode
The temperature of the exhaust system is not
high enough to perform the test. Operate the
engine to raise the exhaust temperatures. Re-
start the Aftertreatment System Functional
Test.
$11C3
Aftertreatment SCR System Not Able to Prime
The SCR dosing system cannot prime. Refer
to Troubleshooting, “DEF Pressure is Low”.
Manual HC Dosing Capability Test
$0002
Active Diagnostic Present
Resolve any active diagnostic codes. Refer to
the appropriate troubleshooting procedure.
$1010
Engine Stopped (No Engine RPM) Start the engine. The test will then progress.
$1155
Diesel Particulate Filter Soot Loading Too High
DPF soot load is above an acceptable level
for safe HC dosing. If soot load events are ac-
tive, refer to the appropriate troubleshooting
procedure.
$116F
Engine Exhaust Gas Recirculation Valve Not
Responding to Command
The EGR valve must have closed to allow HC
dosing to start and/or the EBPR to elevate ex-
haust back pressure to increase exhaust tem-
perature. Check for associated EGR valve
diagnostic codes. Run the “Air System Motor
Valves Verification Test” to check for correct
operation of the EGR valve.
$1108
Excessive Engine RPM Change
The engine speed has changed significantly
during the test which can affect the service
test assessment capability. Rerun the test
without changing engine speed.
$10F5
Excessive Change in Engine Load
The engine load has been changed signifi-
cantly during the test which can affect the
service test assessment capability. Rerun the
test without changing engine load.
$11CA
Aftertreatment Diesel Oxidation Catalyst Con-
version Efficiency Too Low
The DOC may be aged so not enough heat is
being generated for the amount of HC dosing
fuel being injected. The DOC may be sulfated.
Run the “Aftertreatment Recovery Procedure”
.
