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
Remove the electrical power from the ECM.

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 each of the ECM connectors. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".
Check the harness and the wiring for abrasion and for pinch points from the ether injection solenoid to the ECM connector.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 the Ether Canisters for Fluid
Ensure that the electrical power is removed from the ECM.
Remove the ether canister from the ether valve.
Determine if the canister is empty.Expected Result:The ether canister is not empty.Results:
OK - The ether canister is not empty. Remove the ether canister from the ether valve for the remainder of this test. Proceed to Test Step 3.
Not OK - The ether canister is empty.Repair: Replace the empty ether canister with a full ether canister. Retry the system.STOPTest Step 3. Check for Signal Voltage at the Harness Connector for the Ether Injection Solenoid
Remove the electrical power from the ECM.
Disconnect the harness connector at the ether injection solenoid.
Restore the electrical power to the ECM.
Proceed to the "Diagnostic Overrides" screen on Cat ET.
Activate the ether injection system. The system will activate for ten seconds.
Check for a signal voltage between the terminals at the harness connector for the ether injection solenoid.
Remove the electrical power from the ECM.Expected Result:The signal voltage is 8.0 0.5 VDC at the connector for the ether injection solenoid.Results:
OK - The signal voltage is 8.0 0.5 VDC at the connector for the ether injection solenoid.Repair: Voltage is reaching the ether injection solenoid. There is a problem with the solenoid. Connect a new ether solenoid to the harness. Verify that the problem has been corrected prior to installing the new solenoid.STOP
Not OK - The signal voltage is not 8.0 0.5 VDC at the connector for the ether injection solenoid. There is a problem in the harness or in a connector between the ECM and the connector for the ether injection solenoid. There may be a problem with the ECM. Proceed to Test Step 4.Test Step 4. Check the Operation of the ECM
Disconnect the J1/P1 ECM connectors.
Fabricate two jumper wires that are long enough to provide a test circuit at the ECM. Crimp connector sockets onto one end of each of the jumper wires.
Remove the wires from terminal locations P1-18 (digital return) and P1-20 (ether injection solenoid) at the ECM connector. Install a jumper wire into each of these terminal locations.
Connect the J1/P1 ECM connectors.
Restore the electrical power to the ECM.
Proceed to the "Diagnostic Overrides" screen on Cat ET.
Activate the ether injection system. The system will activate for ten seconds.
Check for a signal voltage between the jumper wires at the ECM connector for the ether injection solenoid.
Remove the electrical power from the ECM.
Restore all of the wiring to the original configuration.Expected Result:The signal voltage is 8.0 0.5 VDC at the ECM for the ether injection solenoid.Results:
OK - The signal voltage is 8.0 0.5 VDC at the ECM.Repair: The ECM is producing the correct signal for the ether injection solenoid. The ECM is OK. The problem is in the harness or in a connector between the ECM and the ether injection solenoid. Repair the wiring harness and/or the connector.
