24610-ZW1-901 Honda SHAFT, SHIFT (A) (Honda Code 6841100).

Illustration 1 g06451106
Aftertreatment #1 Function Test had an issue (error code 11C2).
Illustration 2 g06451099
Aftertreatment #2 Function Test has no errors (FFFD error code).
Cat® Electronic Technician (ET) will list the status of each aftertreatment system as "Failed", but the problem may only be related to one of the two systems. If an FFFD error code (no error in current bank) is generated on a machine with multiple aftertreatment systems, toggle between the status of each bank to determine the actual cause of the service test failure. Refer to Illustration 1 and Illustration 2 above for clarification.Service Error ID's are displayed when the Cat ET service test has failed. The Service Error ID's are to help explain why the service has test failed. There could be cases when the service test error ID will isolate the failed component. If applicable use the appropriate troubleshooting procedure.
Table 1
Aftertreatment System Functional Test
FFFD No Service Test Error No error in the current bank.
0002 Active Diagnostic Present Resolve any active diagnostic codes. Refer to the appropriate troubleshooting procedure.
0006 Aborted By User The service test was canceled by the user.
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.
10A7 Coolant Temperature Too Low Allow the engine to warmup.
1010 Engine Stopped (No Engine RPM) Start the engine.
105F Test Timed Out Low temperature pop-up window not closed in time or DCU taking more time than is normally required to power on/off. Displays when the load is not high enough to raise the exhaust temperature.
1169 Engine Exhaust Back Pressure Too Low The SCR catalyst inlet pressure sensor may not be installed in the exhaust stream, or the exhaust piping is leaking, or is disconnected. Refer to Troubleshooting, SCR Catalyst Inlet Pressure is Low.
11AA Aftertreatment SCR Catalyst Reagent Temperature Too Low The temperature of the DEF is too low. Operate the engine to raise the DEF Temperature. If the problem persists, Refer to Troubleshooting, DEF Temperature is Low.
11A8 Aftertreatment SCR Catalyst Conversion Efficiency Too Low Refer to Troubleshooting, NOx Conversion is Low.
11A9 Aftertreatment Outlet NH3 Too High Ammonia slip is happening. Cause could be poor quality DEF or engine running at high load conditions. If the problem persists, Refer to Troubleshooting, NOx Conversion is Low
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 "Aftertreatment System Functional Test" to raise the exhaust temperatures.
11B9 Aftertreatment #1 SCR Catalyst Intake Gas Temperature Too Low 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".
11BB Diesel Exhaust Fluid Level Too Low The DEF tank level is too low to perform the test successfully. Add DEF to the tank.
11BE Ambient Air Temperature Too Low Ambient temperature is below −45° C (−49° F). The Dosing Control Unit (DCO) cannot operate in these low ambient conditions.
11C2 Aftertreatment SCR System in Warmup Mode The DEF is not thawed. Operate the engine to raise the DEF Temperature. If the problem persists, Refer to Troubleshooting, DEF Temperature is Low
1126 Ground Speed Too High Make sure that the equipment is stationary with the parking brake engaged.
1218 Aftertreatment NOx Conversion Efficiency Detected on Incorrect Bank Pump pressure lines between bank one and bank two are swapped or the NOx sensor wiring harness connectors are swapped for the outlet NOx sensors.
1219 Aftertreatment Diesel Exhaust Fluid Pump #1c Not Able to Prime The first pump in the current bank is not in normal dosing mode after power cycle. There could be other active codes which prevents the pump from starting. If the problem persists, Refer to Troubleshooting, DEF Pressure is Low.
121A Aftertreatment Diesel Exhaust Fluid Pump #2c Not Able to Prime The second pump in the current bank is not in normal dosing mode after power cycle. There could be other active codes which prevents the pump from starting. If the problem persists, Refer to Troubleshooting, DEF Pressure is Low.
121B Aftertreatment Diesel Exhaust Fluid Pumps Not Able to Prime Both pumps in the current bank are not in normal dosing mode after power cycle. There could be other active codes which prevents the pump from starting. If the problem persists, Refer to Troubleshooting, DEF Pressure is Low.
122A Aftertreatment NOx Sensors Installation Incorrect The inlet or outlet NOx sensors are installed in the incorrect Aftertreatment bank. Verify the installation location of the NOx sensors then perform the service test again.
Aftertreatment Dosing System Functional Test
FFFD No Service Test Error No error in the current bank.
0002 Active Diagnostic Present Resolve any active diagnostic codes. Refer to the appropriate troubleshooting procedure.
0006 Aborted By User The service test was canceled by the user.
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.
1011 Engine Running (Engine RPM Present) The test cannot run with the engine running, turn the engine OFF.
