Diagnostic Codes Table
Code Conditions which Generate this Code System Response
2417-5 Ether Injection Control Solenoid : Current Below Normal The Electronic Control Module (ECM) detects low current in the circuit. The code is latched. The code is logged.
Ether injection is disabled.
2417-6 Ether Injection Control Solenoid : Current Above Normal The ECM detects excessive current flow in the circuit. The ether injection system improves cold weather starting of the engine. The ECM controls the ether injection system. The ether injection system is enabled when all of the following conditions occur:
The configuration parameter is enabled or the configuration parameter is set to continuous flow.
The intake manifold air temperature is less than 0 °C (32 °F) or the engine coolant temperature is less than 0 °C (32 °F).
Engine speed is greater than 0 rpm and less than 50 rpm below the low idle speed.
No diagnostic codes are active for both the engine coolant temperature sensor and for the intake manifold air temperature sensor.

Troubleshooting Test Steps Values Results
1. Check the Harness Connectors
A. Verify that the keyswitch is in the OFF position.
B. Disconnect the harness connector for the ether solenoid.
C. Check the harness connector for debris and for corrosion.
Connectors
Result: The harness connector was not free of debris and/or not free of corrosion.
Repair: Perform the following procedure:
1. Clean the harness connector.
2. Reconnect the harness connector. Verify that the connection is secure.
3. Verify that the problem is resolved.
If the problem is not resolved, proceed to Test Step 2.
Result: The harness connector was free of debris and free of corrosion.
Proceed to Test Step 2.
2. Create an Open at the Harness Connector for the Ether Injection Solenoid
Note: The ether canister must be removed prior to performing this procedure.
A. If necessary, disconnect the harness connector from the ether solenoid.
B. Turn the keyswitch to the ON position.
C. A test on Caterpillar Electronic Technician (ET) allows the technician to activate the ether system. The test can be activated by selecting the "Diagnostic Overrides" screen on Cat ET.
D. Activate the ether injection system. The system will activate for 10 seconds.
E. Measure the voltage across terminal 1 and terminal 2 of the harness for the ether injection solenoid.
F. Turn the keyswitch to the OFF position.
Voltage
Result: The voltage measurement is 0 VDC after activating the ether injection system.
Repair: There is a problem in the harness. Repair the harness or replace the harness.
Verify that the problem is resolved.
STOP
Result: The voltage measurement is equal to battery voltage after activating the ether injection system.
Repair: There is a problem in the solenoid. Replace the solenoid.
Verify that the problem is resolved.
STOP
Test Step 1. The procedure corrected the issue. Return to service.Results:
The procedure did not correct the issue. - Repair: Contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).STOP
