Fuel shutoff valve
Fault:
When the engine is stopped by turning off the fuel shut off valve, the fuel pressure in the low pressure line drops very slowly.

Fuel shut-off valve stuck open.
If a malfunction code of 55040 or 55041 was also generated, there may be a short circuit in the electrical circuit. Otherwise, either the fuel shut-off valve or the fuel supply pressure sensor is faulty.
Notes:
When the engine is turned off with the ignition key, the solenoid valves will continue to try to keep the engine running, while the fuel shut-off solenoid valve sends a signal to turn off the engine. If this fails, i.e. the pressure in the fuel line will not decrease, a malfunction code is generated, after which the engine is turned off by the electromagnetic valves.
The fault code is generated only in the case of three consecutive failed attempts to shut down.
While the fault is active, the maximum engine torque is reduced by 30%.
Since the DTC is generated when the engine is turned off, it can only be deleted after the engine has been successfully turned off.
Please note that the oil pressure sensor, fuel temperature sensor and mass flow sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors.

The emergency shutdown switch, which in this case is connected to the connecting node to control the functions set by the bodybuilder, is pressed (grounded).
Notes:
If the vehicle speed is lower than the set speed (it can be adjusted in SDP3), but, a maximum of 20 km / h, the engine is turned off.
If the vehicle speed exceeds the set value, as long as there is a fault, this leads to activation of the fuel supply control in the amount of 0% and normal speed in idle mode. This allows the use of power steering and other systems.
The cruise control system is turned off and cannot be activated until the fault has been repaired.
The fault ceases to be active as soon as the emergency shutdown switch is reconfigured.
