Table 1
Code and Description 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 ECM can only detect this condition when the output driver is not activated. 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 ECM can only detect this condition when the output driver is activated. The ether injection system improves cold weather starting. The ECM has full control of the ether injection system. The ECM utilizes information from control maps and engine sensors in order to calculate the flow demand for the ether system during engine starting.The ether injection system is disabled if there is an active engine shutdown.A feature on the Caterpillar Electronic Technician (ET) allows the technician to manually override the ether solenoid in order to diagnose problems with the system. The override feature remains functional while the engine speed is zero rpm. Access the test via the "Override Parameters" screen on Cat ET.

Troubleshooting Test Steps Values Results
1. Inspect the Electrical Connectors and the Wiring
A. Turn the keyswitch to the OFF position.
B. Thoroughly inspect ECM connectors and the connectors for solenoid. Also inspect the circuit from the ECM connector to the ether injection solenoid. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
C. Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
D. Check the harness and the wiring for abrasion and for pinch points from the ether injection solenoid to the ECM.
Connectors and Wiring
Result: The connectors and the wiring appear to be OK.
Proceed to Test Step 2.
Result: There is a problem in the connectors and/or wiring.
Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled. Verify that the repair eliminates the problem.
If the problem is not resolved, proceed to Test Step 2.
2. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: No diagnostic codes are active.
Repair: The problem may have been related to a faulty connection in the harness. Carefully reinspect the connectors and wiring. If an intermittent electrical problem is suspected, refer to Troubleshooting, "Electrical Connectors - Inspect".
If the problem is not resolved, proceed to Test Step 3.
Result: A high current diagnostic code (-6) is active at this time.
Proceed to Test Step 3.
Result: A low current diagnostic code (-5) is active at this time.
Proceed to Test Step 4
3. Create an Open Circuit at the Connector for the Ether Solenoid and Check for Active Codes
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the ether solenoid.
C. Turn the keyswitch to the ON position.
D. Proceed to the "Diagnostic Overrides" screen on Cat ET.
E. Proceed to
