AUTOPHIX 7770 For Mercedes Benz Car Full System OBDII Diagnostic Tool Maintenance Tester Functions: 1. Read fault codes, erase fault codes, read data streams, version information. 2. Support all automotive modules: engine control module, electronic selector module, electronic stability program, transmission control module, steering column module, instrument cluster. 3. Electronic parking brake: reset the brake pads after repairs in the electronic parking brake system. Deactivate and activate the brake control system, auxiliary brake fluid control, turn the brake pads on and off, etc. 4. Electronic power steering: When the vehicle is unstable, based on the calculation of the CPU, the electronic power steering system can brake each wheel independently and participate in the management of the engine system to ensure the safety of driving. 5. TPMS system: allows you to check the tire sensor ID on the vehicle and perform TPMS programming and reset after replacing or rotating the tire sensor. 6. SRS system: SRS is a device that inflates the airbag to protect passengers before a second collision occurs, called the supplemental restraint system (SRS). 7. ABS system: ABS automatically controls the braking force of the brakes when the car brakes, so that the wheels are not locked and are in a state of side rolling (slip rate is about 20 percent ) to ensure maximum adhesion between the wheels and the ground. 8. SAS system: allows you to perform calibration of the steering angle sensor, which permanently stores the current steering wheel position as the front sensor EEPROM. After successfully calibrating the sensor, its fault memory will be automatically cleared. 9. Battery matching system: allows the scan tool to evaluate the battery charge level, monitor short-circuit current, record battery changes, activate vehicle sleep mode and charge the battery through the diagnostic socket. 10. Air conditioning system: supports daily maintenance of the air conditioning module, such as air conditioning system adaptive reset, air conditioni
