Ash Service Reset
The engine ash model must be reset whenever the filter is cleaned or replaced. This resets the DPF volume back to the "Clean State". The resetting will allow the regeneration of the DPF to function properly.
Use Cat ET to access the configuration parameters. In the "System Settings" group of parameters, highlight the "Diesel Particulate Filter Ash Service Reset". Refer to Illustration 1 for the location of the " Diesel Particulate Filter Ash Service Reset". The value of the parameter should be "Not Reset".
Click the "Change" button at the bottom of the screen. The change will require the Factory Passwords to be reset. Enter "Reason Code" 67 or 68.
Contact the Global Highway Call Center at 1-800-447-4986 and select Option 1. The analyst will collect the necessary information in order to make a record of the phone call, and the analyst will enter the following information into the space for the call history: serial number of the DPF, mileage and hours. The analyst will provide the factory passwords that are needed to reset the ash model.
Enter the factory passwords. The value of the parameter will change to "Reset". This indicates that the ash model was reset to "Zero Ash".
