What are the highlights of Autel MD808 Pro?

Autel MD808P Special Functions:

The MaxiDiag MD808 Pro provides Oil Reset, EPB, SAS, DPF and BMS functions for most modern vehicles on the road today. Select the Service function from the Main Menu to access the five special functions.

  • Oil Reset: The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use.
  • An oil change is required whenever indicated by the display and according to the recommended maintenance schedule. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a service indicator being turned on, also reset the system.
  • EPB: This electric parking brake (EPB) function has a multitude of uses to maintain the electronic braking systems safely and effectively.
  • SAS: Steering Angle Sensor Calibration permanently stores the current steering wheel position as the straight-ahead position in the steering angle sensor EEPROM. Therefore, the front wheels and the steering wheel must be set exactly to the straight-ahead position before calibration. In addition, the vehicle identification number is also read from the instrument cluster and stored permanently in the steering angle sensor EEPROM. On successful completion of calibration, the steering angle sensor fault memory is automatically cleared.
  • DPF: The DPF function allows you to carry out numerous functions on the Diesel Particulate Filter system without having to send your car to the main dealer.
  • The tool will manage DPF regeneration, DPF component replacement teach-in and DPF teach-in after replacing the engine control unit.
  •  BMS: The BMS (Battery Management System) allows the scan tool to evaluate the battery charge state, monitor the close-circuit current,
  • register the battery replacement, activate the rest state of the vehicle, and charge the battery via the diagnostic socket.`
  • ABS Maintenance: The tool can read codes, erase codes, record live data, read ECU information, perform active tests, and perform special functions.

OBDII Diagnostic Functions

OBD II Diagnostics function is a fast-access option that allows you to carry out a quick test on the drive train systems of OBD II vehicles.
When more than one vehicle control module is detected by the scan tool, you will be prompted to select the module where the data may be retrieved.
The most often to be selected are the Power-train Control Module [PCM] and Transmission Control Module [TCM].

1. System Status: Select this function to display the system status of the test vehicle, refer to the following description for the system status of the test vehicle.

2. Read Codes: Read Codes can be done with the key on engine off (KOEO) or with the key on engine running (KOER).
This function is used to read the detailed information of a particular diagnostic trouble code for technicians to better solve the problem.

3. Erase Codes: Erase Codes are performed with a key on engine off (KOEO). This function is used to delete diagnostic trouble code when the fault that caused the specific DTC is fixed.

4. Live Data: In this function, you can not only read the live data but also record data for later review.

5. Freeze Frame: Freeze Frame Data allows the technician to view the vehicle's operating parameters at the moment a DTC (Diagnostic Trouble Code) is detected. For example, the parameters may include engine speed (RPM), engine coolant temperature (ECT), or vehicle speed sensor (VSS) etc. This information will aid the technician by allowing the parameters to be duplicated for diagnostic and repair purposes.

6. I/M Readiness: I/M Readiness function is used to check the operations of the Emission System on OBD II compliant vehicles. It is an excellent function to use prior to having a vehicle inspected for compliance with a state emission program.

7. O2 Monitor Test: OBD II regulations set by SAE require the relevant vehicle monitors and tests on the oxygen (O2) sensors to identify problems related to fuel efficiency and vehicle emissions. These tests are not on-demand tests and they are done automatically when engine operating conditions are within specified limits. These test results are saved in the on-board computer's memory. The O2 Monitor Test function allows retrieval and viewing of O2 sensor monitor test results for the most recently performed tests from the vehicle's on-board computer.The O2 Monitor Test function is not supported by vehicles that communicate using a controller area network (CAN).

8. Component Test: The Component Test function allows initiating a leak test for the vehicle's EVAP system. The scan tool itself does not perform the leak test but commands the vehicle's on-board computer to start the test. Different vehicle manufacturers might have different criteria and methods for stopping the test once it has been started. Before starting the Component Test, refer to the vehicle service manual for instructions to stop the test.

9. Vehicle Information: The Vehicle Info. function enables retrieval of Vehicle Identification No.(VIN), Calibration ID Nos. (CINs), Calibration Verification Nos. (CVNs) and In-use Performance Tracking on 2000 and newer vehicles that support Mode.

Difference between MD808 PRO, MD808 and MD802:

  1. MD808 PRO support all system diagnostic for cars while MD808 only support 4 system.
  2. MD808 PRO is an upgraded version of MD802 with more special services like SAS learning, DPF regeneration, BMS service, and Throttle matching while MD802 can't perform such service.
  3. Additional, MD808 Pro can perform diagnostic for more systems.
