(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.
616-6 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.
Follow the troubleshooting procedure in order to identify the root cause of the fault. If there is an active engine shutdown, the ether injection system is disabled.Activation of the ether starting aid is based from a map using the coolant temperature, intake manifold temperature, and atmospheric pressure. Refer to Illustration 1.
Illustration 1 g02445796The following conditions must be met for the ether injection system to be enabled:
Ether injection is set to enabled in the ECM parameters
Engine coolant temperature is less than the "Start Aid Selection Temperature - Coolant". Refer to Illustration 1.
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.

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 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 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 of the seals are properly in place and ensure that the connectors are correctly 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. Connect a digital voltmeter across the two terminals on the engine harness connector for ether control.
E. Turn the keyswitch to the ON position.
F. Measure the voltage across the terminals 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. Refer to the Electrical Schematic for the application. The problem may be inside an electrical connector. Make the necessary repairs.
Proceed to Test Step 4.
Result: The voltage measured greater than 10 VDC.
The electrical components between the ECM and the harness connector for the ether control are OK.
Proceed to Test Step 3.
3. Measure the Resistance of the Coil Inside the Ether Control
A. Verify that the ether control is not connected to the engine harness.
B. Measure the resistance of the coil inside the ether control.
20 Ω
Result: The measured resistance was approximately 20 Ω.
Proceed to Test Step 4.
Result: The measured resistance was not approximately 20 Ω.
Repair: Replace the ether control.
Proceed to Test Step 4.

4. Verify the Repair
A. Activate the Ether Injection Override.
B. Verify that the plunger moved up when the override was active.
Plunger movement
Result: The plunger moved up when the override was active.
Install the ether bottle and return the unit to service.
If the procedure did not correct the issue, contact the Dealer Solutions Network (DSN).
