1. How to Use MB Star Diagnosis
for Excellent Maintenance
Mercedes Benz cars and trucks. Generally speaking, Star Diagnosis has
several or all of the following features:
① read fault codes;
② clear fault codes;
③ read dynamic data flow engine;
④ oscilloscope function;
⑤ element actuation test;
⑥ matching, and other settings and encoding functions;
⑦ calculator and other auxiliary functions.
Some Star multiplexer come with diagnostic manuals, so it is easy for users to
follow the instructions to operate. In general the following steps is necessary
for maintenance:
① find diagnostic seat in the vehicle;
② use the appropriate diagnostic interface;
③ according to model, enter the appropriate diagnostic systems;
④ read fault codes;
⑤ see the data stream;

2. ⑥ clear fault code maintenance after diagnosis.
Although methods of using mb star diagnostic system is relatively simple, but
to give full play to the functions of the instrument and quickly identify failures,
maintenance personnel should pay attention to the following instructions to do
something when using Star Diagnosis.
1. Combine the fault content and symptom to analysis for quickly determining
the cause of failures
Use fault code query function of the diagnostic tool for scanning the electronic
control system in the vehicle. In most cases, the fault records are not the
cause of failures. But the content of the fault record provides us for
determining the scope of the fault. If we combine the records with the failure
phenomenon and other laboratory examinations, we can quickly troubleshoot
problems.
2. According to the storage contents of multiple failures, analyze
and discover their common causes
In most cases, when we reading DTCs function for troubleshooting, we will
bring up a plurality of the fault records. Sometimes the contents of these
failures are not isolated and often caused by a hidden fault, or have certain
causal relationship. If we analysis the fault stored content in this way and with
other detection methods and maintenance experience, we can quickly
determine the fault on Mercedes Benz cars by mb star diagnostic tool.

3. 3. Make full use of the data stream query function
By querying the data stream, we can learn data about related sensors and
actuators of the control unit and switch status information. The data will have
a specific numerical display. So to make full use of these data will help
determine the correct analysis and failure.
4. Emphasise on the meaning of the status information data
Data the control unit by mb star dianostic system can be read in a variety of
ways, and the unit is probably not the same.
In addition to these four use essentials, there are many functions of mb star
diagnostic tool can be brought in to play in the detection and maintenance, to
maximize the application. The key I wan to share with fresh maintanance
personnel is to make rich systematic theoretical knowledge closely related to
maintenance practice, so that the information provided for the user can be
fully utilized.
