Information:
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
There have been instances of the following diagnostic codes becoming active:
Table 1
J1939 Code CDL Code Code Description
1184-3 3782-3 Engine Turbocharger #1 Turbine Outlet Temperature : Voltage Above Normal
1184-4 3782-4 Engine Turbocharger #1 Turbine Outlet Temperature : Voltage Below Normal
3242-3 2452-3 DPF #1 Intake Temperature Sensor : Voltage Above Normal
3242-4 2452-4 DPF #1 Intake Temperature Sensor : Voltage Below Normal
4360-3 3105-3 Aftertreatment #1 SCR Catalyst Intake Gas Temperature Sensor : Voltage Above Normal
4360-4 3105-4 Aftertreatment #1 SCR Catalyst Intake Gas Temperature Sensor : Voltage Below Normal One root cause of the diagnostic codes has been identified as electrical noise overwriting data on the memory chip of the DPF/SCR intake temperature sensor. Improved sensor firmware has resolved this issue.A fault could not be found with some of the returned parts. A new troubleshooting procedure has been released. Refer to Troubleshooting, Sensor Signal (PWM) - Test.
