Engine shut-off
| Engine shut-off |
The normal method is when the control module energizes the high-pressure control valve in the diesel pump. This is done by pin 105 on the control module going high, which makes the engine stop due to the control valve remaining closed so that the high-pressure pump cannot supply fuel for injection. This method is used if the vehicle speed is less than 5 km/h and the engine speed less than 1300 rpm.
If the above conditions are not met, the engine is turned off by the desired value of the injection quantity being set to 0 mg/combustion.
| Diagnostics |
If the vehicle speed is less than 5 km/h and the engine speed less than 1300 rpm when the ignition is turned to OFF (+15 low), the engine speed should drop to below 200 rpm after 1.3 seconds.
If the engine speed is not less than 200 rpm after 1.3 seconds, diagnostic trouble code P0606 will be generated and the engine turned off. This is done by setting the desired value of the injection quantity to 0 mg/combustion.
