Schematic for 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. Verify the Status of the Ether Injection SystemVerify that the ether injection system has been programmed to ON.Results:
OK - The ether injection system has been programmed to ON. Proceed to Test Step 2.
Not OK - The ether injection system has not been programmed to ON. Program the ether injection system to ON. Verify that all of the conditions are met in order for the ether injection system to function properly. Proceed to Test Step 2.Test Step 2. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect ECM connector J1/P1, customer connector J61/P61, and all other connectors in the wiring harness. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the sensor connectors that are associated with the circuit.
Check the allen head screw on each ECM connector and the customer connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Inspect the following components for damage, for corrosion, and for incorrect attachment:
Battery posts
Alternator
Breaker
Engine ground
Chassis groundExpected Result:All connectors, pins, and sockets are completely inserted and coupled. The harness and wiring are free of corrosion, of abrasion, and of pinch points. All connections and grounds are tight and free of corrosion.Results:
OK - The harness and wiring are OK. Proceed to Test Step 3.
Not OK - There is a problem with the harness and/or wiring.Repair: Repair the circuit.Verify that the repair eliminates the problem.STOPTest Step 3. Check the Switch Circuit at the J1/P1 ECM Connector
Reconnect the J61 Customer Connector.
Disconnect the J1 ECM Connector.
Connect one end of the voltage test lamp to J1-22 and connect the other end of the voltage test lamp to P61-22. Refer to illustration 1 for details.
Turn the keyswitch to the ON position. The engine must be OFF.
Operate the ether switch and observe the voltage test lamp.Expected Result:The voltage test lamp will turn ON when the switch is closed. The voltage test lamp will turn OFF when the switch is opened.Results:
OK - The voltage test lamp turned ON when the switch was closed. The voltage test lamp turned OFF when the switch was opened. The switch is operating correctly. Proceed to Test Step 4.
Not OK - The voltage test lamp failed to function according to the expected results. There is a problem in the wiring.Repair: Repair the wiring and/or replace the wiring. Verify that the repair eliminates the problem.STOPTest Step 4. Test the Ether Start Relay
Turn the keyswitch to the OFF position.
Connect the test lamp between the terminals of the ether start relay.
Turn the keyswitch to the ON position.
Activate the ether switch.Expected Result:The test lamp should turn ON for three seconds.Results:
OK - The test lamp did turn ON for three seconds. Proceed to Test Step 5.
Not OK - The test lamp did not turn ON for three seconds. Proceed to Test Step 6.Test Step 5. Test the Voltage at the Ether Valve
Turn the keyswitch to the OFF position.
Disconnect the wires from the ether valve.
Connect the voltage test lamp between the wires that were removed from the ether valve.
Turn the keyswitch to the ON position and start the engine.
Activate the ether switch.Expected Result:The voltage test lamp should turn ON for three seconds.Results:
OK - The voltage test lamp turned ON for 3 seconds.Repair: Temporarily install a new ether valve. Verify that the problem no longer exists. Reinstall the old ether valve. If the problem reoccurs, replace the old ether valve.Verify that the repair eliminates the problem.STOP
Not OK - The voltage test lamp did not turn ON for three seconds. There is a problem in the wiring between the ether valve and the ether start relay.Repair: Repair the connectors or wiring and/or replace the connectors and wiring.STOPTest Step 6. Test the Voltage at the Ether Start Relay
Turn the keyswitch to the OFF position.
Disconnect the wires from the ether start relay.
Connect the voltage test lamp between the drive line wire for the ether start relay and the negative battery.
Turn the keyswitch to the ON position and start the engine.
Activate the ether switch.Expected Result:The voltage test lamp should turn ON for three seconds.Results:
OK - The voltage test lamp turned ON for three seconds. Proceed to Test Step 8.
Not OK - The voltage test lamp did not turn ON for three seconds. Proceed to Test Step 7.Test Step 7. Check the Circuit for the Ether Injection System
Turn the keyswitch to the OFF/RESET position.
Remove J1-21 from ECM Connector J1.
Install one end of a jumper wire into the socket for J1-21.
Connect one lead of the voltage test lamp to the other end of the jumper wire.
Connect the other lead of the voltage test lamp to negative battery.
Turn the keyswitch to the ON position and start the engine.
Activate the ether switch.Expected Result:The voltage test lamp should turn ON for three seconds.Results:
OK - The voltage test lamp turned ON for three seconds. There is a problem in the wiring between J1 and the ether start relay.Repair: Repair the connectors or wiring and/or replace the connectors and wiring.STOP
Not OK - The voltage test lamp did not turn ON for three seconds.Repair: Perform the following diagnostic procedure.
Temporarily connect a test ECM.
Remove all jumpers and reco
