2.Start Diagnostic
After entering the system, the functions that can be implemented include：
* Identification
* Read Fault code
* Erase Fault code
* Actual Values
* Actuators
Adjustment/Settings、Function Test、S* Advance Functions：pecial function, calibration etc.
Specific functions will be different according to different models of the brand and the system, take Bosch engine in Foton engine system as an example:
3 Identification
Identification is the vehicle and system information in ECU. When the vehicle control unit need to be replaced, it is necessary to read the original control unit information and record it as a reference for purchasing a new control unit. When the new control unit is encoded, the original control unit information is required.

Read the fault code function can read ECU fault code to help maintenance personnel quickly found the cause of vehicle failure.
5 Erase Fault code
Clear the fault code stored in the ECU.
Note: General models, please follow the regular order, first read the fault code, and record (or print) and then clear the fault code, test, read the fault code again to verify, repair the vehicle, clear the fault code, test again to confirm the fault code The current hard fault code can not be cleared, if the oxygen sensor, knock sensor, mixed gas correction, cylinder fire and the like type of technical code can be removed immediately, but in a certain period will appear. Must be completely troubleshooting after the fault code will not appear again.

4.Click “Close”, the status of the action test is off.
5.Click “Exit” to exit this action test.
8 Advanced Function
Advance Functions：Adjustment/Settings、Function Test、Special function, calibration.
For example: diesel fuel injector code, idle speed adjustment, broken cylinder test, calibration and so on.
