7.5 Throttle Matching (ELEC. THROTTLE RLRN)
This function can 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.
