Aftertreatment System Functional Test
Service Error Identifiers Description Troubleshooting
$0002 Active Diagnostic Present Resolve any active diagnostic codes. Refer to the appropriate troubleshooting procedure.
$0006 Service Test Aborted by Tool/monitor Abort by user, restart the test.
$0009 Service Test Aborted by ECM Check the service tool connection, do not abort the test before the test is complete. Repeat the test, if necessary.
$10FC Engine Speed Too High Lower the engine speed to idle.
$1010 Engine Stopped (No Engine RPM) Start the engine.
$105F Test Timed Out Not all conditions were met in order for the test to complete. Restart the Aftertreatment System Functional Test.
$11A8 Aftertreatment SCR Catalyst Conversion Efficiency Too Low The SCR system NOx conversion is too low to perform the test. Refer to Troubleshooting, "NOx Conversion is Low".
$11A9 Aftertreatment Outlet NH3 Too High There is too much NH3 in the exhaust. Perform an ARD ignition test to raise the exhaust temperatures.
$11AA Aftertreatment SCR Catalyst Reagent Temperature Too Low The temperature of the DEF is too low. Operate the engine to raise the DEF Temperature.
$11B5 Aftertreatment #1 NOx Level Sensors Not Ready The NOx sensors have not reached the correct temperature to start reading the NOx Level. Perform an ARD ignition test to raise the exhaust temperatures.
$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 allow DEF dosing to initiate. Restart the Aftertreatment System Functional Test.
$11BA Aftertreatment SCR System Not Ready To Dose The SCR system detects that it cannot dose due to the engine operating temperatures not being high enough. Restart the Aftertreatment System Functional Test.
$11BB Diesel Exhaust Fluid Level Too Low The DEF tank level is too low to successfully perform the test. Add DEF to the tank.
$11C2 Aftertreatment SCR System In Warm-up Mode The temperature of the exhaust system is not high enough to perform the test. Operate the engine to raise the exhaust temperatures. Restart 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".
$1164 Engine Speed/Load Incorrect The engine speed or load is above a threshold, remove the load from the engine or reduce the engine speed to idle.
