Cummins ISB CM850 (2003-06) Fault Code: 1694 PID: SPN: 3234 FMI: 2 Aftertreatment Outlet NOx Sensor – Data Erratic, Intermittent, or Incorrect. An incorrect NOx sensor reading has been detected by the aftertreatment outlet NOx sensor. On-Board Diagnostics (OBD) information (Euro 4 Stage 1+ Certified Engines): 1)The ECM illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.2)An engine torque derate will be activated after 50 hours of engine operation with the fault code active.3)The ECM turns OFF the malfunction indicator lamp (MIL) after 1 ignition cycle that the diagnostic runs and...

Cummins ISB CM850 (2003-06) Fault Code: 1697 PID: SPN: 3489 FMI: 3 Aftertreatment #1 Air Enable Actuator ? Voltage Above Normal, or Shorted to High Source. High signal voltage has been detected at the catalyst air solenoid circuit. This fault code is logged when the supply voltage to the air solenoid is greater than +12 volts. Possible causes: 1)Air solenoid signal wire shorted to a voltage supply2)Failed dosing control unit. On-Board Diagnostics (OBD) Information (Euro 4 Certified Engines): 1)The ECM illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.2)The ECM turns OFF the malfunction indicator lamp (MIL)...

Cummins ISB CM850 (2003-06) Fault Code: 1698 PID: SPN: 3489 FMI: 4 Aftertreatment #1 Air Enable Actuator ? Voltage Below Normal, or Shorted to Low Source. Low signal voltage has been detected at the catalyst air solenoid circuit. This fault code is logged when the supply voltage to the air solenoid is less than +12 volts. Possible causes: 1)Open circuit in the air solenoid signal wire2)Open circuit in the air solenoid return wire3)Shorted to pin to pin air solenoid signal wire4)Failed air solenoid5)Failed dosing control unit. On-Board Diagnostics (OBD) Information (Euro 4 Certified Engines): 1)The ECM illuminates the malfunction indicator...

Cummins ISB CM850 (2003-06) Fault Code: 1699 PID: SPN: 1761 FMI: 2 Catalyst Tank Level Sensor – Data Erratic, Intermittent, or Incorrect. Catalyst solution level is not changing with engine operating conditions. This fault code is triggered when the catalyst solution level reading in the catalyst tank does not change with engine operating conditions. If the catalyst dosing control unit indicates that catalyst injection has occurred, but the catalyst tank level has not changed, this fault code will be triggered. This fault will also be triggered if catalyst injection has not occurred, but a drop in the level of the...

Cummins ISB CM850 (2003-06) Fault Code: 1711 PID: SPN: 3361 FMI: 9 Dosing Control Unit Data Link ? Abnormal Update Rate. Data Link communications between the ECM and the Dosing Control Unit have been interrupted. Possible causes: 1)Loss of battery voltage to the Dosing Control Unit2)Loss of battery ground to the Dosing Control Unit3)Loss of keyswitch input to the Dosing Control Unit4)Shorted or open J1939 data link wiring between the Dosing Control Unit and the primary engine ECM5)Failed Dosing Control Unit6)The external OEM controlling device has failed or can no longer transmit on the data link.
