Diagnostic Trouble Codes for Ether Injection
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
626-5 2417-5 Ether Injection Control Solenoid : Current Below Normal The Electronic Control Module (ECM) detects the following conditions:
A low current condition in the output from the ECM to the solenoid for ether injection
The ECM has been powered for at least 2 seconds.
If equipped, the warning lamp will come on. The ECM will log the diagnostic code.
626-6 2417-6 Ether Injection Control Solenoid : Current Above Normal The Electronic Control Module (ECM) detects the following conditions:
A high current condition in the output from the ECM to the solenoid for ether injection
The ECM has been powered for at least 2 seconds.
If equipped, the warning lamp will come on. The ECM will log the diagnostic code. If there is an active engine shutdown, the ether injection system is disabled . The ether system will be disabled if the glow plugs have been activated in the last 5 minutes.Activation of the ether starting aid is based on the minimum temperature from one of the following temperature sensors:
Intake manifold temperature sensor
Air intake temperature sensor
Coolant temperature sensorRefer to Illustration 1.
Illustration 1 g06396017The following conditions must be met for the ether injection system to be enabled:
Ether injection is set to "Enabled" in the ECM parameters
Ether Solenoid Configuration is set to Continuous Flow Solenoid in ECM configuration parameters.
The lower of the intake manifold air temperature, the air inlet temperature, or the coolant temperature is less than the activation point for ether start aid. Refer to Illustration 1.
The maximum temperature of the intake manifold air temperature sensor, the air inlet temperature sensor, or the coolant temperature sensor is below 50° C (122° F).During the following procedure, refer to the electrical schematic for the application.Complete the procedure in the order in which the steps are listed.

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Remove the electrical power from the ECM.
B. Thoroughly inspect the ECM connector J1/P1. Inspect all 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 correct torque of 6 N m (53 lb in).
E. Check the harness and the wiring for abrasion and for pinch points.
Loose connection or damaged wire
Result: The harness and wiring are OK.
Proceed to Test Step 2.
Result: There is a fault in a connector or the wiring.
Repair: Repair any faulty connectors or replace the wiring harness. Ensure that all the seals are properly in place and ensure that the connectors are correctly coupled. Proceed to Test Step 8.
2. Check the Status of the Ether Start Aid
A. Use the electronic service tool to check the "Cold Start Status" screen.
Ether start aid status
Result: The ether start aid is "Disabled".
Repair: The following conditions must be met before ether is enabled for the next engine start:
• The engine must be started without using ether.
• The engine must be run at greater than low idle for at least 5 seconds.
• The Selective Catalytic Reduction (SCR) temperature (if applicable) must reach at least 120° C (248° F).
Result: The ether start aid is "Enabled".
Proceed to Test Step 3.
3. Check for Active or Logged Diagnostic Codes
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. Connect the electronic service tool to the diagnostic connector.
D. Turn the keyswitch to the ON position.
E. Check for active or logged diagnostic codes that relate to the ether injection system or the glow plug starting aid system.
Diagnostic codes
Result: No diagnostic codes are present.
Repair: There may be an intermittent fault in an electrical component between the ECM and the harness connector for the ether control. The problem may be inside an electrical connector. Refer to Troubleshooting, "Electrical Connector - Inspect".
Result: A 676-5 or 676-6 (2246-5 or 2246-6) code is present.
Refer to Troubleshooting, Glow Plug Starting Aid - Test.
Note: A Glow Plug fault will disable the Ether system.
Result: A 626-5 or 2417-5 code is present.
Proceed to Test Step 4.
Result: A 626-6 or 2417-6 code is present.
Proceed to Test Step 6.
4. Create a Short at the Solenoid Connector
A. Verify that the keyswitch is in the OFF position.
B. Disconnect the harness connector from the ether solenoid.
C. Fabricate a jumper wire and install the jumper wire between terminal 1 and terminal 2 on the harness connector for the ether solenoid.
D. Turn the keyswitch to the ON position.
E. Access the "Diagnostic Overrides" screen on the electronic service tool and then activate the ether injection system.
Diagnostic code
Result: A 626-5 or 2417-5
