Fault code D600

Fault

The solenoid valve for injection timing on the 
rear bank, cylinder 4-6, is faulty.

Cause

Short circuit to +24 V alternatively between pin 
9 and 10 on connector A1.

Remarks

As a result, the engine runs very unevenly and 
the whole rear bank (cylinder 4-6) will 
probably be shut off.

Action

Check the wiring and clean the connectors.

Clear the fault code memory. Start the engine 
and accelerate the engine to full speed.

If the fault remains, renew the injection timing 
solenoid valve.

Fault code D601

Fault

The solenoid valve for injection timing on the 
rear bank, cylinder 4-6, is faulty.

Cause

Pin 9 and 10 on connector A1 shorted to earth.

Remarks

As a result, the engine runs very unevenly and 
the whole rear bank (cylinder 4-6) will 
probably be shut off.

Action

Check the wiring and clean the connectors.

Clear the fault code memory. Start the engine 
and accelerate the engine to full speed.

If the fault remains, renew the injection timing 
solenoid valve.

Fault code D602

Fault

The solenoid valve for injection timing on the 
rear bank, cylinder 4-6, is faulty.

Cause

Open circuit to pin 9 and 10 on connector A1.

Remarks

As a result, the engine only runs on three 
cylinders.

Action

Check the wiring and clean the connectors.

Clear the fault code memory. Start the engine 
and accelerate the engine to full speed.

If the fault remains, renew the injection timing 
solenoid valve.

Fault code D603

Fault

The solenoid valve for injection timing on the 
rear bank, cylinder 4-6, is faulty.

Cause

Monitoring pin 9 and 10 on connector A1 
indicates implausible values compared to other 
solenoid valves.

Remarks

As a result, the engine runs very unevenly and 
the whole rear bank (cylinder 4-6) will 
probably be shut off.

Action

Check the wiring and clean connector A1, B2 
and the connector to the solenoid valve.

Clear the fault code memory. Start the engine 
and accelerate the engine to full speed.

If the fault remains, first renew the control unit 
and if necessary the injection timing solenoid 
valve.

Fault code D604

Fault

The solenoid valve for injection timing on the 
rear bank, cylinder 4-6, is faulty.

Cause

Monitoring pin 9 and 10 on connector A1 
indicates that the voltage is too low to control 
the solenoid valve.

Remarks

As a result, the engine will probably run very 
unevenly.

The engine torque is limited by approximately 
30%.

Action

If fault code 3201 is also present, low battery 
voltage is active, rectify the battery fault first.

Check the wiring and clean connector A1, B2 
and the connector to the solenoid valve.

Clear the fault code memory. Start the engine 
and accelerate the engine to full speed.

If the fault remains, first renew the injection 
timing solenoid valve and if necessary the 
control unit.

Fault code D700

Fault

Open circuit in the fuel shut-off valve.

Cause

The control unit sends high frequency pulse 
signals to the fuel shut-off valve and has 
discovered that the signal is always too high.

This may be caused by an open circuit in the 
leads to the fuel shut-off valve or an open 
circuit within the fuel shut-off valve.

Alternatively, pin 4 on connector B2 may be 
shorted to +24 V.

Remarks

If there is an open circuit on the leads or in the 
fuel shut-off valve, the fuel supply will be shut 
off and the engine will stall.

If pin 4 on connector B2 is shorted to +24 V, 
the valve is constantly open.

Action

Check the wiring and the fuel shut-off valve.
