What does Sid 146 mean on an engine?
SID 146 indicates that during engine operation the EGR system is experiencing operation outside the normal range, resulting in one or more of the following fault codes. • EGR Temperature Above Normal (146/0) • EGR Temperature Below Normal (146/1) • Bad Component (146/12) • EGR – Valve is Not Responding (146/7) • Data Erratic (146/2)
What causes a VT365 injector failure in a school bus?
This type of plumbing can lead to those domino type of failures where a problem in one component takes out a component down the line. The VT365s VGTurbo depends on engine oil pressure to move its vanes so there is no key on, key off movement like in a DT466.
Where can I find the Mercedes Fault code?
Any of the scanners listed above can read and clear the Check Engine / Service Engine Fault Codes. The codes above are retrieved by plugging a diagnostic scanner into the OBD-II port located under the dash, and scanning for fault codes. Location of OBD II port used to retrieve Mercedes-Benz fault codes.
What does SID mean in a fault code?
This part of the fault code explains what the parameter or system identification is. The classification of this is detailed on the SAE document that is why you need this to understand what SID, PID, PPID, PSID you need to look up. All of that raw data in the example above means something!
What is the fault code for a mid 128 engine?

What does it mean when your fault code is J1587?
Meaning that you have no load or resistance since an EGR motor is a resistor. You need to check for rubbed wires or you need to replace your EGR valve to fix this fault code. Check the resistance of the EGR motor, it should be less than 10 ohms based on the manufacture spec. You can have the same fault code with multiple failure modes.
Where are the fault codes located on the J1587 bus?
Thats it! You now are an expert of fault codes that are located on the J1587/J1708 protocol. This protocol is largly used on modules within the trucking industry so you will come across these type of fault codes with Engine / ABS / Brakes / Climate Control / Instrument clusters and other modules that are located on the J1587/J1708 Bus.
What’s the standard fault code for a truck?
This communication is usually more common on trucks that are older than 2013 year model year. The most common protocol for the trucking industry is J1939, which communicates at the faster 250k baud rate. Let’s look at this first example fault code:
