The vehicle power supply has to meet the normal voltage limits DC4.8V---5V. 3.2.2. When pull and plug test wire harness, users should pinch the front-end of the wire harness
- 9. EZ300 Diagnosis System 9 to pull and plug, not pull the middle section of the wire harness. Users should check the corresponding direction of the port and plug in horizontally when they plug the wire harness, instead of inserting in an oblique way, which may damage the terminal. 3.2.3. When taking some special functions tests, users are required to operate the device according to operating instructions. For vehicle, it has to strictly meet the requirements, for example, the conditions that some vehicle models need to be reached are as follows: engine temperature 80 ℃/105℃, turn off the loads (such as headlights, air conditioner, etc.), put accelerator pedal in released position, etc. 3.2.4. The ECU for Chinese domestic vehicle models are relatively disorderly, so when users meet conditions, such as the car can not be tested or the test data is wrong, they should consider whether the selected menu corresponds to the tested electronic control system, or they can find the car ECU and select the right menu according to the model number on the ECU label. 3.2.5. If users can not find the tested vehicle model or electronic control system in EZ300 test menu, they may need to update the software or consult Xtool technical service department 3.2.6. Banned to have connection test by using harness not from Xtool to avoid unnecessary losses. 3.2.7. Banned to power off directly in the communication between EZ300 and vehicle. Users should cancel the task and return to the main interface, then power off. 3.2.8. The device should be put and lifted slightly to avoid collision when using EZ300. When click the screen, touch it gently to guarantee the service life of the touch screen. 3.2.9. During long period of non-use, please disconnect the power and turn it off. 4. Diagnosis 4.1. Menu Options 4.1.1. After VCI box connected to vehicle and paired with EZ300 mainframe via wired or wireless means, diagnosis can be performed now. The diagnostic interface comes up as below.
- 10. EZ300 Diagnosis System 10 4.1.2. Users can choose menu based on their actual needs: selection for Europe means entering European cars menu, selection for Asia means entering Asian cars menu, selection for America means entering American cars menu, selection for China means entering Chinese cars menu. Users also can input vehicle model to search. 4.2. Test Functions 4.2.1. Take Volkswagen car for example, select Diagnosis, then select Europe Car, users can see Volkswagen’s logo. If the logo has not been seen, please swipe up and down or enter the car model to research. Different vehicles have slight different menus. Common main function menu includes the following options: Read ECU: this function is to read ECU version information, which is the equivalent of “System Identification” or “System Information” in some electronic control systems, all mean to read ECU related software and hardware versions, models and production date of diesel engine, part number, etc. It is convenient for us to make record in the maintenance process, and it also makes later date feedback and management easier. Read DTCs: read trouble codes stored in ECU. Clear DTCs: clear current and historical trouble codes memory in ECU, under the premise that all the troubles are eliminated. The trouble codes can not be erased without eliminating all the troubles, which will cause the diagnostic tool always reading the trouble code because the code will always be saved in ECU. Suggestion: users should better not to clear trouble codes, we need record the trouble details after reading code, which is provided as reference for maintenance. After dealing with troubles, there will be no trouble code when we re-read. Read Live Data: that is to read the parameters of running engine, such as oil pressure, temperature, engine speed, fuel oil temperature, coolant temperature, intake air temperature, etc. Based on these parameters, we can judge directly where the problem lies, which helps to narrow the scope in maintenance. For some vehicles, during their actual operation, the problems such as
- 11. EZ300 Diagnosis System 11 performance characteristics offset, sensitivity reduction, can be judged in live data. This function needs us very familiar with engine parameters, for instance, when idle speed is 800RPM or 750RPM, coolant operating temperature is between 80-105℃, what are the operating voltage and time of each sensor and actuator? 4.2.2. Toolbar function buttons descriptions Function Buttons Descriptions Returns to previous interface Print testing data Click it to record the data, click again to send your feedbacks to XTOOL after service center Record data feedback button as shown below, showing diagnostic software version and various information in the diagnostic process. 4.3. Read ECU This function is to read ECU version information, which is the equivalent of “System Identification” or “System Information” in some electronic control systems, all mean to read ECU related software and hardware versions, shown as below.
- 12. EZ300 Diagnosis System 12 4.4. Read DTCs Select Read Trouble Codes to read trouble codes stored in ECU. Screen will show the trouble code and its definition when read the trouble codes, shown as below. Tip: In the process of diagnosis, if the device shows “System is OK” or “No Trouble Code”, it means there is no related trouble code stored in ECU or some troubles are not under the control of ECU, most of these troubles are mechanical system troubles or executive circuit troubles, it is also possible that signal of the sensor may bias within limits, which can be judged in Live Data.
- 13. EZ300 Diagnosis System 13 4.5. Clear DTCs 4.5.1. Return to the previous step, select Clear DTCs to clear current and historical trouble codes memory in ECU. Performing this function will clear all the current and historical trouble codes. Make sure whether the trouble codes have been recorded before clearing, shown as below. 4.5.2. Click YES to make clear confirmation, if the communication is normal, it will show “Trouble Codes Successfully Cleared” or “Trouble Codes Cleared”. Generally, users need re-read trouble codes after cleaning them to confirm whether the trouble codes have been cleared. 4.6. Read Live Data Auto ECUs send out operating parameters and working status of various components in the form of Electronic Signal, here Electronic Signal refers to Live Data. Common Engine Live Data includes Engine Speed, Throttle Position Sensor Voltage, Oxygen Sensor Voltage, Coolant Temperature, Spark Advance Angle, Idle Speed Switch State, Intake Air Temperature, Intake Pressure, etc.
- 14. EZ300 Diagnosis System 14 Tips: Live Data is the important function for maintenance technicians to further diagnose the troubles. This function needs maintenance technicians very familiar with sensor data of each system, control signals and control modes, all which are the indispensable basis of using Live Data function for maintenance technicians. (The following is test conditions and typical values of common live data) Test Items Unit Normal Data Test Conditions & Typical Values 1.Engine Speed rpm 0-6000 Engine warmed-up: 750-850rpm 2.Engine Coolant Temperature ℃ -40-150 Engine warmed-up: 85-95℃ 3.Throttle Percentage 0-100 Throttle closed:0%, Throttle wide-open: ＞ 85 4.Injecting Pulse Width ms 0-15 Engine warmed-up: 3.5-4.5ms 5.Intake Air Temperature ℃ -40-150 Show value a little higher than ambient temperature 6.Battery Voltage v 0-15 Idle speed: 1.5-13.5V 7.Injection closed-loop correction 0-1.99 8.Load ms 0-15 9.
