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. In order for this diagnostic code to be enabled, the engine speed must be present. 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 ECM can only detect this condition when the output driver is activated. In order for this diagnostic code to be enabled, the engine speed must be present. The ether injection system improves cold weather starting of the engine. The ECM controls the ether injection system.The ether injection system is disabled if there is an active engine shutdown.A test on Caterpillar Electronic Technician (ET) allows the technician to activate the ether system. The test is functional when the engine speed is zero rpm. Access the test via the "Override Parameters" screen on Cat ET. The test will not generate a diagnostic code.

Schematic of the ether injection system
Breathing ether vapors or repeated contact of ether with skin can cause personal injury. Personal injury may occur from failure to adhere to the following procedures.Use ether only in well ventilated areas.Do not smoke while changing ether cylinders.Use ether with care to avoid fires.Do not store replacement ether cylinders in living areas or in the operator's compartment.Do not store ether cylinders in direct sunlight or at temperatures above 49 °C (120 °F).Discard cylinders in a safe place. Do not puncture or burn cylinders.Keep ether cylinders out of the reach of unauthorized personnel.To avoid possible injury, be sure the brakes are applied and all controls are in Hold or Neutral when starting the engine.
Test Step 1. Inspect the Electrical Connectors and the Wiring
Turn the keyswitch to the OFF position.

(1) J1/P1 ECM connectors
Thoroughly inspect connectors (1). Inspect the connector for the ether solenoid. Refer to Troubleshooting, "Electrical Connectors - Inspect".

Perform a 45 N (10 lb) pull test on each of the wires that are associated with the ether injection system.
Check the torque of the allen head screws for the ECM connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and the wiring for abrasion and for pinch points from the ether injection solenoid to the ECM. Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The connectors and the wiring appear to be OK. Proceed to Test Step 2.
Not OK - The connectors and/or the wiring are not OK.Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. Verify that the problem is resolved.STOPTest Step 2. Check for Voltage to the Ether SolenoidNote: Remove the ether canister before you perform this procedure.
Turn the keyswitch to the OFF position.
Disconnect the connector for the ether solenoid.
Turn the keyswitch to the ON position.
Measure the voltage between terminal 1 and terminal 2 on the harness side of the connector for the ether solenoid.
Proceed to the "Diagnostic Overrides" screen on Cat ET.
Activate the ether injection system. The system will activate for ten seconds.
Measure the voltage between terminal 1 and terminal 2 on the harness side of the connector for the ether solenoid. Expected Result:The voltage measures approximately 0 VDC when the override for the ether system is not activated. The voltage measures approximately 24 3 VDC when the override for the ether system is activated.Results:
OK - The voltage measurements are correct.Repair: Check the ether solenoid for an open or a short circuit. The resistance of the coil in the ether solenoid is approximately 20 Ohms. STOP
Not OK - One of the voltage measurements was incorrect.Repair: There is either a short or an open in the wiring between the connector for the ether solenoid and the ECM. Repair the wiring and/or connectors. STOP
