5.2 | Press stop engine button (S11), then also press start engine button (S10) and bring engine into the crankshaft position of the selected adjustment method | When cranking engine using starter in the case of engines up to engine end number 394441. | |
The engine will not start when the engine stop button (S11) and engine start button (S10) are pressed simultaneously. | |||
5.3 | Using XENTRY, switch off actuation of unit pumps and move engine to crankshaft position for selected adjustment method by pressing engine start/engine stop button (S10.1) | When cranking engine using starter in the case of engines as of engine end number 394442. | |
Switching off actuation of the unit pumps via XENTRY means that the engine will not start. After switching off the ignition or disconnecting in the meantime the diagnostic system, the unit pump actuation is activated again and then the engine can start. | |||
