Follow on-screen instructions to select appropriate execution options, enter correct values or data, and perform necessary actions. The application will display detailed instructions to complete selected service operations.
NOTE 1. Always reset the engine oil life to 100% after every oil change. 2. All required work must be carried out before the service indicators are reset. Failure to do so may result in incorrect service values and cause DTCs to be stored by the relevant control module. 3. For some vehicles, the scan tool can reset additional service lights such as maintenance cycle and service interval.
6.4 Battery Management System (BMS) Service The BMS allows the 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. NOTE 1. This function is not supported by all vehicles. 2. The sub functions and actual test screens of the BMS may vary by vehicle, please follow the on-screen instructions to make correct option selection.
IMPORTANT Before diagnosing a problem vehicle and attempting to perform an emergency regeneration, it is important to obtain a full diagnostic log and read out relevant measured value blocks. NOTE 1. The DPF will not regenerate if the engine management light is on, or there is a faulty EGR valve. 2. The ECU must be re-adapted when replacing the DPF and when topping up the fuel additive Eolys. 3.
6.7 Steering Angle Sensor (SAS) Service Steering Angle Sensor (SAS) Calibration permanently stores the current steering wheel position as the straight-ahead position in the SAS EEPROM. Therefore, the front wheels and the steering wheel must be set exactly to the straight-ahead position before calibration. In addition, the VIN is also read from the instrument cluster and stored permanently in the SAS EEPROM. On successful completion of calibration, the SAS fault memory is automatically cleared.
