How to use Post-Processing Diagnostics

Introduction

Aftertreatment Diagnostics is a valuable tool available on heavy-duty vehicles from model year 2007 with J1939 data. It displays information related to the aftertreatment system, including Diesel Particulate Filter (DPF) indicators, their status, inhibitions and sensor readings of DPF, EGR, SCR and tank diagnostics DEF in an easy to understand graphical way.

Using Post-Processing Diagnostics

1. Select the Post-Processing Diagnostics button on the main toolbar.

2. If you are connected to a vehicle, Aftertreatment Diagnostics instructions will automatically display to help you diagnose problems with aftertreatment systems. Once closed, instructions can be reopened by clicking on the “Instructions” button.

Overview of the Post-Processing Diagnostics Window

3. The Post-Processing Diagnostics overview window appears, and an “Overview” tab displays a diagram of the post-processing system. Key data points identified include readings from the tank's DPF, EGR, SCR and DEF sensors.

Additional information per component

Click on the engine, DPF, SCR or DEF tank to view additional information about the selected component. The bidirectional test button, if available, will change depending on the selected component. Clicking the button will display a filtered list of post-processing bidirectional tests for the selected component. At the top of the “Overview” tab are the appropriate indicators, including the Stop Engine Light, Check Engine Light, Diesel Particulate Filter (DPF) Light, and High Exhaust Temperature Light , as well as indicators of DPF degradation, regeneration zone and the need for DPF regeneration.

My name is Sofiane, I was born in Lyon in 1996. I grew up in a modest family and I have always been fascinated by cars since I was very young.

After my high school studies, I decided to specialize in the automotive field. So I went to study automotive engineering in Grenoble where I obtained a master's degree in mechanical engineering for passenger vehicles.

Passionate about OBD (On-Board Diagnostic) technology, which allows drivers to diagnose their car themselves using the elaborate system embedded in their vehicles connected via Bluetooth/Wi-Fi or USB with a compatible personal computer such as Windows PC/ Linux/MacOsX such as ELM327 WiFi), I started my professional career as a technical writer after having completed several practical internships with different Lyon automobile garages in order to deepen my technical knowledge for this sector and acquire sufficient practical experience necessary that could be useful when products software achievements.

Over the years, I had developed some additional passions in particular: travel, computing (IOT & IP Networks) and Jazz music. It is thus that thanks to these additional skills enriched during all his extra-professional adventures that he was able to establish a bridge between his professional and private life offering him more equally interesting and diversified professional opportunities

I like working on complex projects linked to this fairly cutting-edge technology (preventive maintenance, advanced engine error diagnostics) because it allows me to take on stimulating technical challenges which constantly improve my skills and my expertise in this sector.

As a technical editor for Bosch France, I often had the opportunity to participate in seminars organized by their partners, suppliers or internal distributors. Thus during a professional trip to China to attend a conference on new trends in the Chinese automotive market ( 2020)
