Diagnostic Trouble Codes for the Intake Valve Actuators    
CDL Code    J1939 Code    Description    Information    
    2950-5     Engine Intake Valve Actuator #1 : Current Below Normal     The ECM monitors the current flow through the circuit for each actuator. If low current flow (open circuit) is detected, a -5 diagnostic code is activated. The ECM continues to try to activate the actuator. If high current flow (short circuit) is detected, a -6 diagnostic trouble code is activated. The ECM will disable the solenoid circuit in order to prevent damage from the high current flow. However, the ECM will periodically try to activate the actuator. If the short circuit remains, this sequence of events will be repeated until the problem is corrected.
The ECM takes the following actions while the code is active:
Engine power is derated by ten percent.
The amber warning lamp is illuminated.
These codes are usually caused by a wiring problem. The wiring problem can be on the outside of the engine or underneath the valve cover.    
    2950-6     Engine Intake Valve Actuator #1 : Current Above Normal    
    2951-5     Engine Intake Valve Actuator #2 : Current Below Normal    
    2951-6     Engine Intake Valve Actuator #2 : Current Above Normal    
    2952-5     Engine Intake Valve Actuator #3 : Current Below Normal    
    2952-6     Engine Intake Valve Actuator #3 : Current Above Normal    
    2953-5     Engine Intake Valve Actuator #4 : Current Below Normal    
    2953-6     Engine Intake Valve Actuator #4 : Current Above Normal    
    2954-5     Engine Intake Valve Actuator #5 : Current Below Normal    
    2954-6     Engine Intake Valve Actuator #5 : Current Above Normal    
    2955-5     Engine Intake Valve Actuator #6 : Current Below Normal    
    2955-6     Engine Intake Valve Actuator #6 : Current Above Normal    
    Follow the troubleshooting procedure in order to identify the root cause of the problem.    System Operation During Engine OperationThe intake valve actuation system does not operate until the engine has reached normal operating temperature. Also, the engine must meet certain operating conditions in order to activate the intake valve actuation system.There are three housings under the valve cover. Each housing contains two actuators. There is a solenoid for each actuator. The ECM sends a command to a solenoid when the ECM requires the intake valves for a cylinder to remain open. The ECM monitors the current flow through the circuit for the solenoid. The ECM activates a diagnostic code if the current flow is below normal or above normal."Intake Valve Actuator Solenoid Test"This test is available on the Caterpillar Electronic Technician (ET). The test helps diagnose problems with the circuits for the solenoids. The following conditions must be met before the test will function:
Engine speed must be zero.
Vehicle speed must be zero.
The transmission gearshift lever must be in neutral.

Troubleshooting Test Steps    Values    Results    
1. Inspect the Electrical Connectors and the Wiring
A. Check the engine harness between the P2 connector and the connectors near the grommets. Look for the following problems:
1. Moisture
2. Loose connectors or damaged connectors
3.Damage that is caused by excessive heat
4. Damage that is caused by chafing
5. Improper routing of wiring
6. Damaged insulation
B.Inspect the connectors near the grommets. The connectors must be clean and dry.
C. Perform a
45 N (10 lb) pull test on each of the wires in the connectors. This test verifies that the wire is properly crimped to the terminal and that the terminal is properly inserted into the connector.
   
Moisture
Damage to connectors    
Result: The wiring is OK.
If you are troubleshooting a -5 code, proceed to Test Step 2.
If you are troubleshooting a -6 code, proceed to Test Step 4.
Result: The wiring is not OK.
Repair the wiring problem. Replace parts, if necessary. Perform the "Intake Valve Actuator Solenoid Test".
If all of the actuators pass the test, troubleshooting is complete. Return the unit to service.
