and ground.
Turn the ECS to the STOP position.
Activate the ether override and observe the voltmeter while ether injection is on. Disable the ether override. Do not allow the ether to be on for more than two minutes. Damage to the solenoid may occur.
Remove all wire jumpers and reconnect all connectors.Expected Result:The voltage at the ECM is 24 3 VDC for two seconds.Results:
OK - The voltage at the ECM is 24 3 VDC for two seconds.Repair: The wire F710-BR and/or the connectors between the ECM and the ether start relay need repair. Inspect the wiring and connectors between the ether start relay and the connector at the ECM. Repair the connectors or wiring and/or replace the connectors or wiring.STOP
Not OK - The voltage at the ECM is not 24 3 VDC for two seconds.Repair: Replace the ECM. Refer to the diagnostic procedure Troubleshooting, "Replacing the ECM".STOPTest Step 9. Check the Voltage from the Ether Hold Relay.
Turn the ECS to the OFF/RESET position.
Connect a voltmeter between wire 926-RD on terminal 30 of the ether hold relay and ground.
Turn the ECS to the STOP position.
Activate the ether override and observe the voltmeter while ether injection is on. Disable the ether override. Do not allow the ether to be on for more than two minutes. Damage to the solenoid may occur.Expected Result:The voltage at terminal 30 is 24 3 VDC during injection.Results:
OK - The voltage at terminal 30 is 24 3 VDC during injection. Proceed to Test Step 10.
Not OK - The voltage at terminal 30 is not 24 3 VDC during injection. Proceed to Test Step 12.Test Step 10. Check the Voltage at the Resistor and the Diode Assembly.
Turn the ECS to the OFF/RESET position.
Disconnect the connector at the resistor and the diode assembly.
Connect a voltmeter to pin 1 of the resistor and the diode assembly and ground.
Turn the ECS to the STOP position.
Activate the ether override and observe the voltmeter while ether injection is on. Disable the ether override. This procedure must be performed on all of the resistor and diode assemblies, if more than one resistor and diode assembly is present. Do not allow the ether to be on for more than two minutes. Damage to the solenoid may occur.Expected Result:The voltage is 24 3 VDC.Results:
OK - The voltage is 24 3 VDC. Proceed to Test Step 11.
Not OK - The voltage is not 24 3 VDC.Repair: There is a problem in the harness between the ether hold relay and the resistor and diode assembly. Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 11. Check the Resistor and Diode Assembly.
Disconnect the connector at the resistor and the diode assembly.
Set the multimeter to the "Check Diode" setting.
Connect the positive lead of the multimeter
