Schematic of the ether injection systemTest Step 1. Check the Circuit Breakers and the Configuration Parameters
Check for tripped circuit breakers.
Use Cat ET to check the status of the configuration parameter for "Ether Control".Expected Result:A circuit breaker is tripped or the configuration parameter for "Ether Control" is disabled.Results:
Yes - A circuit breaker is tripped or the configuration parameter for "Ether Control" is disabled.Repair: If a circuit breaker is tripped, reset the circuit breaker. Determine the cause of the incident.If the configuration parameter for "Ether Control" is disabled, use Cat ET to enable the parameter.STOP
No - No circuit breakers are tripped. The configuration parameter for "Ether Control" is enabled. Proceed to Test Step 2.Test Step 2. 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 in the ECM connector that are associated with the ether injection system.
Check the allen head screw on each ECM connector for the proper torque. Also check the allen head screw on the customer connector for the proper torque. 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 wiring appear to be OK. Proceed to Test Step 3.
Not OK - The connectors and/or wiring are not OK.Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. Verify that the problem is resolved.STOPTest Step 3. Check the Ether Canister for Starting Fluid
Remove the electrical power from the ECM.
Remove the ether canister from the ether valve. Determine if the canister contains fluid.Expected Result:The ether canister is not empty.Results:
OK - The ether canister is not empty. Do not install the ether canister. Proceed to Test Step 4.
Not OK - The ether canister is empty.Repair: Replace the empty ether canister with a full ether canister. Verify that the original problem is resolved.STOPTest Step 4. Check the Voltage at the Ether Start Relay
Remove the electrical power from the ECM.
Connect Cat ET to the service tool connector.
Remove the wire from terminal 87 of the normally open contacts of the ether relay that goes to the ether injection solenoid.
Connect a voltmeter between terminal 87 of the ether relay and ground.
Restore the electrical power to the ECM.
Select the "Diagnostic Tests" on Cat ET.
Select the "Override Parameters" screen on Cat ET.
Activate the ether override. The ECM will activate the ether injection system for ten seconds.
Measure the voltage at the ether relay while the ether injection system is activated.
Deactivate the ether override.
Remove the electrical power from the ECM.
Reconnect the wire to terminal 87 of the ether relay.Expected Result:The measured voltage is between 9 VDC and 15 VDC for 12 volt systems. The measured voltage is between 22 VDC and 27 VDC for 24 volt systems.Results:
OK - The voltage is within the acceptable range. Proceed to Test Step 5.
Not OK - The voltage is not within the acceptable range. Proceed to Test Step 6.Test Step 5. Check the Voltage at the Ether Injection Solenoid
Remove the electrical power from the ECM.
Disconnect the electrical connector for the ether injection solenoid.
At the harness connector for the ether injection solenoid, connect a voltmeter between terminal 1 and engine ground.
Restore the electrical power to the ECM.
Select the "Diagnostic Tests" on Cat ET.
Select the "Override Parameters" screen on Cat ET.
Activate the ether override. The ECM will activate the override for ten seconds. Observe the voltmeter while the ether injection system is activated.
Deactivate the ether override.
Remove the electrical power from the ECM.
Connect all of the connectors.Expected Result:The measured voltage is between 9 VDC and 15 VDC for 12 volt systems. The measured voltage is between 22 VDC and 27 VDC for 24 volt systems.Results:
OK - The voltage is within the acceptable range.Repair: Verify that the wire from the ether injection solenoid to the −Battery has continuity. If the wire is OK, replace the ether injection solenoid.STOP
Not OK - The voltage is not within the acceptable range.Repair: Inspect the wiring and connectors between the normally open conta
