Conditions:
- on-board voltage >XX V (XX - Measured values group XXX field X
- intake air temperature > X °C
- engine speed = X
Note:
- done after replacement of component: throttle valve, engine control unit
- done after repair of components: throttle valve, engine control unit
connect with the control unit XX - engine
Erasing of learning values
Note:
- if the adaptation values have already been deleted at this stage, then do not redo this adaptation value deletion process to prevent deletion of already adapted components
- if the adaptation values are now deleted, it is necessary to do basic setting (adaptation) of ALL subordinate actuators that require this, e.g. EGR, EVAP, throttle valve, etc.
