2.3.5 Actuation Test This function is used to find out whether a specific subsystem or component in vehicles goes well or not, by testing output elements instead of checking in ignition status. 2.3.6 Special function This function is used for data writing operation of electronic control unit. They all belong to this category, such as ECU data calibration, ECU Programming etc. Some Resetting functions are also included in this part. 3. Services TOPDON Phoenix Smart is equipped with maintenance services to be very beneficial for technicians and mechanics working in the automotive repair industry.
3.1 OIL (Maintenance Light Reset) This function enables you to reset the oil service lamp for the engine oil life system, which calculates an optimal oil life change interval depending on the vehicle driving conditions and weather events. It needs to be performed in the following cases: • If the service lamp is on, run car diagnostics first for troubleshooting. After that, reset the driving mileage or driving time, so as to turn off the service lamp, and enable a new driving cycle. • If you have changed the engine oil or electric appliances that monitor oil life, you need to reset the service lamp.
3.2 ETS (Throttle Matching) This function can utilize the car decoder to initialize the throttle actuator so that the learning value of the ECU returns to the initial state. By doing so, the movement of the throttle (or idle motor) can be more accurately controlled, thus adjusting the intake volume. It needs to be performed in the following cases: • After replacing the electronic control unit, the relevant characteristics of the throttle operation have not been stored in the electronic control unit. • After the electric control unit is powered off, the memory of the electric control unit is lost. • After replacing the throttle assembly, you need to match the throttle.
• After replacing or disassembling the intake port, the controlling of the idle speed by the coordination between the electronic control unit and the throttle body is affected. • The intake volume and the idle control behavior has changed while staying at the same throttle opening position, although the idle throttle potentiometer behavior hasn’t changed. 26
