Preconditions for the test:
Ignition on.
No faults stored.
Battery voltage min. 11,5 volt.
All electrical loads switched off.
Throttle at idling position.
If cruise control is fitted, it must be working properly.
Note:
The basic setting matches (”adapts”) the throttle control unit to the engine control unit.
See also the readiness test.
Adaption must be done when:
The throttle control unit has been removed from the vehicle.
The throttle control unit has been replaced.
If the electric power supply to the engine control unit has been disconnected.
If the engine control unit has been replaced.
Carry out adaption of the throttle control unit:
Choose the throttle control unit function.
The throttle control unit operates in the min and max positions and several different intermediate positions. The control unit stores the corresponding throttle angle in the permanent memory. After adaption, the throttle returns to the starting position briefly, then closes.
During adaption, ”Adaption in progress…” shows in the adaption status field. When adaption has been done, ”Adaption OK!” / ”Adaption Error” is displayed. For the basic setting to be stored, the ignition must remain switched off for at least 15 seconds.
