Причина
Возможные причины:
• Датчик давления в топливной магистрали показывает неправильные значения.
• Неисправность перепускного клапана.
• Неисправность в электрической цепи датчика давления наддувочного воздуха, датчика температуры наддувочного воздуха, датчика температуры охлаждающей жидкости или датчика скорости работы вентилятора.
Примечания
Датчик давления в топливной магистрали, датчик температуры охлаждающей жидкости, датчик давления наддувочного воздуха, датчик температуры наддувочного воздуха и датчик скорости работы вентилятора имеют общее электропитание. В случае неисправности в одном из датчиков, она может затронуть электрические цепи других датчиков.
В течение всего времени, когда давление в топливной магистрали превышает установленное значение, электромагнитный клапан отсечки подачи топлива закрыт. Если неисправен датчик давления топлива, то электромагнитный клапан прекращения подачи топлива при работе двигателя постоянно открыт.

EMS Scania Engine Control Unit Fault codes list: 50178-65532

See also: Scania trucks service repair manuals PDF

Blocks:

2098557, 2098556, 2110163, 2110160

Title:

Pump nozzle cylinder 5

Fault:

Too slow increase of current in the winding of the solenoid valve. The rise time of the current is determined by the control unit, depending on the voltage of the battery and the temperature of the coolant.

The reasons:

• The fault may be due to too high resistance, the reason for which may be:
• Open circuit between control unit and solenoid valve.
• Damaged wiring.
• Open circuit inside the control unit.

Notes:

The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%.

Elimination:

1. Check the electrical components, electrical connectors and wiring.
2. Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.
3. Clear the trouble code memory.
4. If there is a malfunction, replace the injector pump first and then the control unit.

Blocks:

2098557, 2098556, 2110163, 2110160

Title:

Pump nozzle cylinder 5

Fault:

Solenoid driver warns of malfunction.

The reasons:

This fault may be caused by a short circuit in the wiring, a short circuit in the solenoid valve, or a short circuit inside the control unit.

Notes:

The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.

If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%.

Elimination:

1. Check the electrical components, electrical connectors and wiring.
2. Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.
3. Clear the trouble code memory.
4. If there is a malfunction, replace the injector pump first and then the control unit.

The reasons:

• Short circuit or open circuit injectors.
• Solenoid valve malfunction pump-injector or mechanical failure of the pump-injector.
• It is also possible for air to enter the fuel line.

Notes:

As a result, there may be some uneven operation of the engine.

Elimination:

1. Check the wiring and clean the connector.
2. Make sure the fuel line to the injector pump is working properly.
3. Remove air from the fuel system.
4. Clear the DTC memory and start the engine.
5. If the DTC remains active, replace the pump injector.

EMS 50181

Blocks:

2098557, 2098556, 2110163, 2110160

Title:

Pump nozzle cylinder 5

Fault:

Too early closing of the solenoid valve injectors. The injection advance angle is earlier than required.

The reasons:

• It is also possible for air to enter the fuel line.
• This fault can also be caused by a short circuit or a break in the electrical circuit of the pump-injector. Solenoid valve malfunction pump-injector or mechanical failure of the pump-injector.

Notes:

As a result, there may be some uneven operation of the engine.

Elimination:

1. Check the wiring and clean the connector.
2. Make sure the fuel line to the injector pump is working properly.
3. Remove air from the fuel system.
4. Clear the DTC memory and start the engine.
5. If the DTC remains active, replace the pump injector.

EMS 50182

Blocks:

2098557, 2098556, 2110163, 2110160

Title:

Pump nozzle cylinder 5

Fault:

Too late closing of the solenoid valve pump nozzle. The injection advance angle is later than required.

The reasons:

The cause of the malfunction may be a jamming of the solenoid valve or an excessively high resistance of the wiring.

Notes:

As a result, there may be some uneven operation of the engine.

Elimination:

1. Check the wiring and clean the connector.
2. Clear the trouble code memory.

Title:

Immobilizer

Fault:

Failed data validation while saving data.

The reasons:

When checking the data was used the wrong key.

Notes:

Starter locked. If the vehicle speed exceeds 20 km / h, the engine speed drops to 500 rpm until the DTC is active.

If the vehicle speed is below 20 km / h, the fuel supply is interrupted, the engine is turned off and cannot be started until the DTC is active.

Elimination:

1. It is only necessary to delete the fault code if no fault codes were generated in the coordinator and the driver did not notice any faults. If any trouble codes are recorded in the coordinator’s memory, start troubleshooting.
2. After completing the troubleshooting, erase the trouble code from the engine control unit. Ensure that this error code is no longer generated during operation.

EMS 50432

Title:

Pump nozzle cylinder 6

Fault:

Too fast increase of current in the coil of the solenoid valve pump-nozzle.

The reasons:

• The fault may be due to a too low resistance of the solenoid valve.
• If a malfunction code 50435 was generated at the same time, it is possible that this is a consequence of a short circuit in the solenoid valve or the wiring. In addition, it is possible that a short circuit has occurred between the valve cover and one of the terminals on the solenoid valve.

Notes:

The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.

If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%.

Elimination:

1. Check the electrical components, electrical connectors and wiring.
2. Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.

Fault:

Too rapid increase in current in the winding of the solenoid valve. The rise time of the current is determined by the control unit, depending on the voltage of the battery and the temperature of the coolant.

The reasons:

• The fault may be due to a too low resistance of the solenoid valve.
• If a malfunction code 50691 was generated at the same time, it is possible that this is due to a short circuit in the solenoid valve or the wiring. In addition, it is possible that a short circuit has occurred between the valve cover and one of the terminals on the solenoid valve.

Notes:

The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.

If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%.

Elimination:

1. Check the electrical components, electrical connectors and wiring.
2. Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.
3. Clear the trouble code memory.
4. If there is a malfunction, replace the injector pump first and then the control unit.

The reasons:

The probable cause of the malfunction is a defect in the bypass valve. It is also possible that the drain line is clogged.

Notes:

A fault code will be recorded only if the pressure in the fuel line exceeds the set value for 7 seconds or a longer time interval. This time period was set to avoid writing code due to short-term pressure fluctuations not caused by functional deviation.

If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value.

Title:

Pressure in the fuel supply system

Fault:

The pressure in the fuel line is well below the set value.

The reasons:

Possible causes of failure:

• One of the two relief valves opens at too low a pressure.
• The fuel shut-off solenoid valve remains closed.
• The fuel filter is clogged.
• Air in the fuel or lack of fuel in the tank.
• Malfunctioning booster pump.
• Significant fuel leak from the system.

Notes:

A fault code will only be generated if the supply pressure is below the allowable pressure for at least 7 seconds. This time period was set to avoid writing code due to short-term pressure fluctuations not caused by functional deviation.

If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value.

With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed).

Elimination:

1. Check for fuel in the tank and bleed the fuel system to remove air from it.
2. Check the opening pressure of both relief valves.
3. Check the position of the fuel shut-off solenoid valve.
4. Check the condition of the fuel filter.
5. Check the fuel priming pump.
6. Check the tightness of the fuel system.
7. If a malfunction has appeared while the car is coasting (when the car is going to descend with the accelerator pedal fully released), then you can use the “Stored operational data” engine parameters stored in the memory to analyze the fault. See “Feed Pressure” section. If the pressure deviation in the fuel line for a specified time interval is -1.0 bar or more, then the fuel filter may be clogged. If there is no significant pressure deviation in the fuel line, then this may be due to jamming of the bypass valve in the open position.

The reasons:

Possible reasons:

• The pressure sensor in the fuel line shows incorrect values.
• Bypass valve malfunction.

Notes:

During the entire time when the pressure in the fuel line exceeds the set value, the fuel shut-off solenoid valve is closed. If the fuel pressure sensor is faulty, then the fuel shut-off solenoid valve when the engine is running is constantly open.

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.

Fault:

High voltage is constantly applied to the outputs of the fuel shut-off solenoid valve.

The reasons:

Open wiring solenoid fuel supply stop or interruption of the winding of the valve itself. The cause of the fault may also be a short circuit to the wire connected to the positive terminal of the battery.

Notes:

If an open circuit occurs, the fuel cut-off solenoid valve closes and the engine stops.

In the event of a short circuit, the fuel shut-off solenoid valve will be constantly open.

Elimination:

Title:

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.

The reasons:

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.

Elimination:

1. Check whether a malfunction code of 55040 or 55041 has been generated. If so, check the fuel shut-off valve and the wiring.
2. If trouble code 55040 or 55041 was not generated, first replace the fuel shut-off valve and then, if necessary, the pressure sensor in the fuel line.
3. As a last resort, replace the alternator charge controller.

Fuel supply to cylinders

Fault:

The torque developed by the front group of cylinders (cylinders 1-3) significantly exceeds the torque developed by the rear group of cylinders (cylinders 4-6).

The reasons:

A malfunction may be due to a failure of one of the fuel supply solenoid valves or an injection advance, which causes an incorrect engine torque for one row of cylinders. This may be due to the following reasons:

• One of the front row solenoid valves of the cylinders supplying too much fuel (too high torque) to cylinders 1-3.
• One of the solenoid valves in the rear row of cylinders that supplies too little fuel (too low torque) to cylinders 4-6.
• If the engine produces a higher power than usual, immediately before the malfunction code is generated, one of the front row solenoid valves may be faulty.
• If the engine produces a lower power than usual, immediately before the malfunction code is generated, one of the solenoid valves in the back row of cylinders may be faulty.
• A fault code can also be generated even if there is no fault in any of the solenoid valves. In some cases, the DTC is caused by faulty pump injectors or fluctuations in the transmission caused by driving conditions.

Notes:

Engine may operate unevenly.

To protect the engine, the maximum engine torque is reduced by 30%.

To generate a DTC, the fault must be present for 6 seconds. If the fault disappears, after three seconds the engine will return to normal operation.

Elimination:

1. To determine whether one of the solenoid valves causes a malfunction, proceed as follows : Switch the solenoid valves so that both the front row solenoid valves are responsible for the rear row and vice versa. Perform a road test car. Attach a load to the engine by performing a full load ride.
2. If fault code 57090 has now been generated, one of the solenoid valves is a possible cause. Replace solenoid valves on the same row of cylinders. Clear the trouble code memory. Perform a road test car.Attach a load to the engine by performing a full load ride.
3. If the fault persists, replace the solenoid valves on another row of cylinders.

Fault:

The torque developed by the front group of cylinders (cylinders 1-3) significantly exceeds the torque developed by the rear group of cylinders (cylinders 4-6).

The reasons:

• One of the fuel control or solenoid injection timing solenoid valves does not work correctly. In this case, the torque developed by one of the two groups of cylinders does not correspond to the specified value.This may be due to the fact that an excess amount of fuel enters the front group cylinders or too little fuel enters the rear group cylinders.
• If the engine is gaining momentum, the front-group cylinder fuel control solenoid valve is stuck in a position where too much fuel flows into the cylinders.
• If the engine is slowing down, the rear cylinder fuel control solenoid valve is stuck in a position where there is too little fuel in the cylinders.
• If the engine drops speed and white smoke appears with the exhaust gases, then the solenoid valve for controlling the injection timing of the rear cylinder group lets in insufficient amount of fuel. Fuel injection starts so late that the fuel can not be ignited.
• A malfunction may also be caused by leakage of the sealing rings on the pump nozzles.

Notes:

Uneven engine performance due to engine speed limiting at 500 … 550 rpm. The fuel shut-off solenoid valve is faulty.

Elimination:

• If the engine starts to gain momentum, then replace the front cylinder group fuel control solenoid valve.
