Figure 5-13 Sample Relevant Repair Info Screen 2 To review relevant cases information 1. Tap the repair case icon to display main page. 2. Scroll through the page and to locate relevant information. 3. Tap the arrow icon at the left top and return to the previous repair case page.
6 Service The Service section is specially designed to provide quick access to the vehicle systems for various scheduled service and maintenance tasks. The typical service operation screen is a series of menu driven executive commands. 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.
2. 3. 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. 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 Battery Management System (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 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 (VIN) is also read from the instrument cluster and stored permanently in the steering angle sensor EEPROM.

8.1.5.2 Main View Section Up to four traces, along with digital readouts of current signal values, signal status and triggering conditions, can be displayed simultaneously on the main view section screen. Each trace has two control features, X-axis and Y-axis, which enable you to adjust the oscilloscope settings to suit the particular test measurement. If multiple traces are displayed at the same time, the Y-axis for each trace is adjusted separately while the X-axis is the same for all traces.
IMPORTANT To prevent electric shock, do not exceed voltage limits between inputs. Channel Selection In the main view section, a channel has two conditions: selected and unselected. A channel must be selected in order for the waveform to be movement, to use the zoom-in or to add voltage rulers. Tap the zero baseline marker or the Y-axis (the line thickens when selected). Figure 8-28 Sample Channel Selection 1 (Selected) Tap the zero baseline marker or the Y-axis again to exit the channel selection.
Figure 8-29 Sample Channel Selection 1 (Unselected) Waveform Zooming The zooming function allows you to change the size and position of a signal during or after capturing a waveform to examine it in greater details. It does not change the stored data, but the way it displays. The X-axis and Y-axis can be zoomed using your fingertips. The waveform can be zoomed during or after capturing the signal.
The two angle rulers are positioned to mark the start and end of a cycle. By default, the start and end angle values are 0° and 720°, which can be configured in the Ruler Setting box. The Voltage/Current Ruler can be generated in the similar way by tapping the Ruler Activator in the upper right corner and dragging it downwards. When Measurement Rulers are generated, a Ruler Table showing time and voltage values for the corresponding channels will be displayed.
