Preconditions for the test:
Ignition on.
No faults stored.
All electrical loads switched off.
Throttle at idling position.
Note:
The basic setting matches (”adapts”) the throttle control unit to the engine control unit.
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. The throttle then remains in the starting position.
When adaption is complete, the relevant column must show: throttle control unit operating condition 0100; adaption status 00.
Exit the basic setting and end communication.
Shut off ignition in 15 seconds to store the new values.
