Cummins ISB CM850 (2003-06) Fault Code: 1716 PID: SPN: 411 FMI: 11 Auxiliary Temperature Sensor Input 1 Circuit – Root Cause Not Known. High temperature detected by the OEM temperature sensor or by the engine coolant temperature sensor.
This fault code indicates that coolant temperature has exceeded the engine protection limits for high coolant temperature.
On-Board Diagnostics (OBD) information:
1)The ECM illuminates the appropriate amber or red fault lamp when the diagnostic runs and fails
2)The ECM turns off the appropriate fault lamp when the diagnostic runs and passes.
Possible repairs:
1)Replace the ECM.
2)Replace the OEM harness.
Cummins ISB CM850 (2003-06) Fault Code: 1713 PID: SPN: 3363 FMI: 0 Catalyst Tank Heater Circuit – Data Valid But Above Normal Operating Range – Moderately Severe Level. The catalyst tank heater is continuously in the on position.
Cummins ISB CM850 (2003-06) Fault Code: 1712 PID: SPN: 3363 FMI: 1 Catalyst Tank Heater Circuit ? Data Valid But Below Normal Operating Range ? Moderately Severe Level. The catalyst solution temperature did not increase when the catalyst tank heater was commanded on.
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.
