Diagnostic Trouble Codes for the Solenoid Valves    
CDL Code    Description    Notes    
18-5     Fuel Control Valve : Current Below Normal     The Electronic Control Module (ECM) detects the following conditions:
Low current in the output from the ECM to the solenoid for the suction control valve on the high-pressure fuel pump for 0.6 seconds
There are no active 168 diagnostic codes.
The ECM has been powered for at least 0.25 seconds.
The Engine System Indicator lamp will come on. The ECM will log the diagnostic code.
This diagnostic code will detect a fault in the circuit for the solenoid in the suction control valve. The fault is most likely to be an open circuit.    
18-6     Fuel Control Valve : Current Above Normal     The ECM detects the following conditions:
High current in the output from the ECM to the solenoid for the suction control valve on the high-pressure fuel pump for 0.6 seconds
There are no active 168 diagnostic codes.
The ECM has been powered for at least 0.25 seconds.
The Engine System Indicator lamp will come on. The ECM will log the diagnostic code.
This diagnostic code will detect a fault in the circuit for the solenoid in the suction control valve. The fault is most likely to be caused by a high side short to ground or a low side short to power.    
526-5     Turbo Wastegate Drive : Current Below Normal     The ECM detects the following conditions:
Low current in the output from the ECM to the solenoid for the wastegate regulator.
There are no active 168 diagnostic codes.
The ECM has been powered for at least 2 seconds.
The Engine System Indicator lamp will come on once the diagnostic code has been active for 30 seconds. The diagnostic code will be logged.
The engine will be derated while this diagnostic code is active. After the engine derate has been activated, the electronic service tool will indicate "Turbo Protection Derate Active".
This diagnostic code will detect a fault in the circuit for the solenoid in the wastegate regulator. The fault is most likely to be an open circuit.    
526-6     Turbo Wastegate Drive : Current Above Normal     The ECM detects the following conditions:
High current in the output from the ECM to the solenoid in the wastegate regulator
There are no active 168 diagnostic codes.
The ECM has been powered for at least 2 seconds.
The Engine System Indicator lamp will come on once the diagnostic code has been active for 30 seconds. The diagnostic code will be logged.
The engine will be derated while this diagnostic code is active. After the engine derate has been activated, the electronic service tool will indicate "Turbo Protection Derate Active".
This diagnostic code will detect a fault in the circuit for the solenoid in the wastegate regulator. This problem is most likely to be caused by a high side short to ground or a low side short to power.    
2461-5     ARD Fuel Pressure #1 Control : Current Below Normal     The ECM detects the following conditions:
Low current in the output from the ECM to the solenoid for the pilot fuel control valve on the Aftertreatment Regeneration Device (ARD)
There are no active 41 diagnostic codes.
The ECM has been powered for at least one second.
The Engine System Indicator lamp will come on. The ECM will log the diagnostic code.    
2461-6     ARD Fuel Pressure #1 Control : Current Above Normal     The ECM detects the following conditions:
High condition in the output from the ECM to the solenoid for the ARD pilot fuel control valve
There are no active 41 diagnostic codes.
The ECM has been powered for at least one second.
The Engine System Indicator lamp will come on. The ECM will log the diagnostic code.
The ECM will try to activate the control valve at 1 second intervals for 10 seconds. If the control valve does not activate, the ECM will disable the control valve until the keyswitch has been cycled.    The following background information is related to this procedure:
Electronically controlled wastegateThe engine has a turbocharger with an electronically controlled wastegate. Typically, the wastegate is a mechanical valve that is used in the turbocharger in order to regulate the intake manifold pressure to a set value.The control system for the electronically controlled wastegate precisely regulates the intake manifold pressure by using a wastegate regulator to control the wastegate.The required intake manifold pressure is calculated by the software that is contained in the ECM. The ECM uses the wastegate regulator to control the wastegate in order to provide the precise value of intake manifold pressure. The solenoid in the wastegate regulator is controlled by a PWM signal from the ECM.Suction control valve for the high-pressure fuel pump:The high-pressure fuel pump is equipped with a suction control valve. The suction control valve precisely controls the amount of fuel that enters the high-pressure fuel pump.The amount of fuel that is required is calculated by the software that is contained in the ECM. The solenoid in the suction control valve is controlled by a PWM signal from the ECM.ARD pilot fuel control valveThe ARD pilot fuel control valve controls the amount of fuel that is injected into the ARD when a regeneration is taking place.The amount of fuel that is required is calculated by the software that is contained in the ECM. The ARD pilot fuel control valve is controlled by a PWM signal from the ECM.
