3. Maintenance Services
TOPDON Phoenix Plus is loaded with maintenance services to be very beneficial for
technicians and mechanics working in the automotive repair industry.
3.1 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 the service lamp is not on, but you have changed the engine oil or electric
•
appliances that monitor oil life, you need to reset the service lamp.
3.2 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's
•
memory 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.
3.3 Steering Angle Reset
This function can reset the steering angle to zero to keep the car running straight.
It needs to be performed generally after replacing the steering angle position sensor,
or after replacing the mechanical parts of the steering system (such as steering gear,
steering column, tie rod ball head, steering knuckle), or after completing the four-wheel
positioning, body repair, etc.
