Information:
Use this procedure in order to troubleshoot the ether system or use this procedure if a diagnostic code in Table 1 is active or logged.
Table 1
Diagnostic Trouble Codes
CDL Code J1939 Code Code Descriptions
(code descriptions may vary) Comments
2417-5 626-5 Ether Injection Control Solenoid : Current Below Normal The code is latched. The code is logged.
Ether injection is disabled.
2417-6 626-6 Ether Injection Control Solenoid : Current Above Normal The code is latched. The code is logged.
Ether injection is disabled. The ether injection system will improve cold weather starting of the engine. The engine Electronic Control Module (ECM) controls the ether injection system. The ether injection system is disabled if there is an active engine shutdown.Activation of the ether starting aid is based from a map using the coolant temperature, intake manifold temperature, and atmospheric pressure. Refer to Illustration 3.
Illustration 1 g02445796The following conditions must be met for the ether injection system to be enabled:
Ether injection is set to enabled in Cat ET
Engine coolant temperature is less than the "Start Aid Selection Temperature - Coolant". Refer to Illustration 3.
Intake manifold temperature is less than the "Start Aid Selection Temperature - IMAT."
Coolant temperature and intake manifold air temperature are within 11° C of each other.Industrial Application Schematic

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Remove the electrical power from the ECM.
B. Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors for the circuit. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".
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 ECM connector (allen head screw) for the proper torque. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".
E. Check the harness and the wiring for abrasion and for pinch points.
Connectors and Wiring
Result: The harness and wiring are 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 coupled. Proceed to Test Step 4.
2. Check the Wiring Between the ECM and the Ether Control
The ether canister must be removed prior to performing this procedure.
A. Verify that the keyswitch is in the OFF position.
B. Remove the ether canister.
C. Disconnect the engine harness connector for the ether control.
D. On a Machine and Electric Power applications, measure the voltage between the two terminals on the engine harness connector for ether control.
On an Industrial application, measure the voltage between terminal 1 on the engine harness connector for ether control and a know good ground source.
E. Turn the keyswitch to the ON position.
F. Measure the voltage while the keyswitch is turned ON.
10 VDC
Result: The voltage measured 0 VDC.
Repair: There is a problem in an electrical component between the ECM and the harness connector for the ether control.
