Test Step 1. Check for Connector Damage.
Check the circuit breakers.
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Check connectors and wiring for the following problems: damage, corrosion, abrasion and incorrect attachment.Expected Result:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - Proceed to test step 2.
Not OK - Repair: Repair the connectors and/or wiring or replace the connectors and/or wiring. Stop.Test Step 2. Check for Diagnostics on the ET.
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position.
Connect the ET.
Determine if CID-FMI 545-05, 545-06, 546-05 or 546-06 is active or logged.
Toggle the Starting Aid Switch. Observe the parameter for the Ether Switch on the ET.Expected Result:The parameter for the Ether Switch should display "ON" while the Starting Aid Switch is toggled. The parameter for the Ether Switch should display "OFF" when the switch is released.Results:
OK - No active codes or logged codes are present. The ether injection system does not inject ether. Proceed to test step 3.
Active Code - Active Diagnostics are displayed. Proceed to test step 4.
Logged Code - Logged Diagnostics are displayed. Check for an intermittent short or open in the wiring or connectorsRepair: Repair the connectors and/or wiring or replace the connectors and/or wiring. Stop.
Not OK - The Starting Aid Switch is not functioning correctly. Proceed to test step 5.Test Step 3. Check the Ether Canisters.
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Remove the ether canister(s) from the ether solenoid(s). Determine if the canister contains any ether. Ether can not be injected if the canister is empty.Expected Result:The canister should not be empty.Results:
OK - Proceed to test step 4.
Not OK - Repair: The ether canister is empty. Replace the ether canister. Ether can not be injected if the canister is empty. Stop.Test Step 4. Check the Voltage At The Ether Solenoid.
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Remove the ether canister(s) from the ether solenoid(s).
Connect the ET.
Turn the circuit breaker to the battery to the ON position.
Turn the ECS to the STOP position.
Insert signal reading probes into the 2 Pin connector for the Ether Solenoid.
Connect a multimeter.
Select the "Diagnostic Tests" on the ET.
Select the "Override Parameters" screen on the ET.
Activate the Ether Override and observe the multimeter while ether injection is "ON". Disable the Ether Override. This procedure must be performed on both solenoids if two are present. Do not allow the ether to be "ON" for more than two minutes. Damage may occur.Expected Result:The voltage at the Ether Solenoid should be 13 to 24 VDC during the first two seconds of injection. The voltage at the solenoid should be 3 to 11 VDC after the first two seconds of injection.Results:
OK - The voltage is approximately 24 VDC for the first two seconds and decreases to about 3 VDC for the remainder of injection.Repair: If ether is not being injected, temporarily replace the Ether Solenoid. If the problem is no longer present, reinstall the old solenoid. If the problem returns replace the solenoid. Stop.
Not 24 VDC - The voltage never reached 24 VDC or the voltage decreased to 3 VDC for the entire test. Proceed to test step 6.
Not 3 VDC - The voltage reached 24 VDC for the first two seconds. The voltage did not decrease to 3 VDC for the remainder of the injection duration. Proceed to test step 7.Test Step 5. Check the Ether Switch Wires at the Harness.
Turn the circuit breaker to the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Disconnect J1/P1 and the Starting Aid Switch.
Obtain a suitable piece of wire. Connect the wires at the Starting Aid Switch together.
Measure the resistance between the ether switch P1-25 and the digital return P1-29.Expected Result:The resistance should be less than 10 Ohms.Results:
OK - The resistance is less than 10 Ohms. The switch wiring is not the problem. Proceed to test step 8.
Not OK - There is a problem with the switch wiring in the harness.Repair: Repair the connectors and/or wiring or replace the connectors and/or wiring. Stop.Test Step 6. Check the Voltage at the Ether Hold Relay.
Turn the circuit breaker to the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Remove the ether canister(s) from the ether solenoid(s).
Connect the ET.
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position.
Measure the voltage from terminal 87 and terminal 87a on the Ether Hold Relay to ground.
Select Diagnostic Tests from the ET.
Select the "Override Parameters" on the ET.
Activate the Ether Override and observe the multimeter while ether injection is ON. Disable the Ether Override. Do not allow ether to be ON more than two minutes. Damage may result.Expected Result:The voltage at terminal 87 should be 13 to 24 VDC during the first two seconds of injection. The voltage from terminal 87a should be 13 to 24 VDC after the first two seconds of injection.Results:
OK - The correct voltage appeared at both terminals. There is a problem in the wiring harness between the Resistor and the Diode Assembly and the Ether Hold Relay.Repair: Repair the connectors and/or wiring or replace the connectors and/or wiring. Stop.
Not OK - Voltage did not appear at either terminal. Proceed to test step 9.
NO Voltage - Voltage appeared at only one of the terminals.Repair: There is an internal problem with the relay. Temporarily replace the relay. If the problem is no longer present, reinstall the old relay. If the problem returns replace the relay. Stop.Test Step 7. Check the Voltage at the Resistor and the Diode Assembly.
Turn the circuit breaker to the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Remove the ether canister(s) from the ether solenoid(s).
Connect the ET.
Turn the circuit breaker to the battery to the ON position.
Turn the ECS to the STOP position.
Use signal reading probes to measure the voltage between pin
